     BOUDIN,  Circuit Judge.    Appellants  Gerardo  Delgado-
                           

Munoz, Leandro  Quinones,  Juan Martinez,  and  Saul  Andino-

Figueroa were  indicted on June  21, 1991, for  conspiracy to

distribute cocaine base,  commonly known as  "crack" cocaine,

in violation of  21 U.S.C.    841(a)(1) and 846.  Delgado was

alleged to  have been the  ringleader of the  operation, with

Quinones  serving  as his  chief  lieutenant  and Andino  and

Martinez  filling  various  subordinate  roles   as  lookout,

courier, driver and guard.

     The indictment  alleged that members  of the  conspiracy

had  sold cocaine base to an undercover operative of the Drug

Enforcement Administration,  Pamela Mersky, on  six different

occasions in April and May 1991.  The transactions, which all

took place in  Boston and  its suburbs, involved  a total  of

896.2 grams of cocaine base, 506 grams of which changed hands

in the  final transaction  on May 30,  1991.  In  addition to

conspiracy,  each  defendant was  charged  with  one or  more

substantive counts  of cocaine distribution  corresponding to

the transactions in which he participated.1

     Appellants and  two other co-defendants were  tried to a

jury  in April  1992.   The  government's evidence  consisted

                    

     1Specifically,  Delgado and  Quinones were  charged with
six   substantive   distribution   counts  arising   out   of
transactions on April 9, 19, 23, May 6, 16, and May 30, 1991.
Andino was charged with four substantive  distribution counts
pertaining  to  the  April   23,  May  6,  16,  and   May  30
transactions.   Martinez  was  charged with  one distribution
count for the May 30 transaction.

                             -3-

primarily of Special  Agent Mersky's testimony, supported  by

tape-recordings of her conversations with the  defendants and

testimony   of   surveillance   agents  who   monitored   the

transactions.   The jury convicted appellants  on all counts.

One co-defendant,  Paulita Cadiz,  was also convicted  on all

counts but has not  appealed; the remaining defendant, Lazaro

Delgado,  was  acquitted.    On  June  29,  1992,  the  court

sentenced Andino to 151 months' imprisonment, Martinez to 240

months' imprisonment, and sentenced Delgado and Quinones each

to 360 months' imprisonment.

     These appeals followed.   Each appellant  except Delgado

challenges his conviction, and all challenge their sentences.

We   first   consider  appellants'   challenges   to  various

evidentiary rulings and instructions at  trial, as well as to

the   sufficiency   of  the   evidence  on   various  counts.

Thereafter, the sentencing issues are addressed.

                     I.  THE CONVICTIONS

     A.  Andino

     We  begin  with the  conviction of  Andino, who  is also

referred to in the indictment as "Bruno."  Andino was alleged

to have assisted Delgado and the others on at least four drug

transactions by watching over the  drugs, conducting counter-

surveillance,  and sometimes by  making the  actual delivery.

He  argues first that the trial  court erroneously admitted a

spontaneous confession made upon his arrest in Puerto Rico.

                             -4-

     Andino was not present at the  May 30, 1991, transaction

between his  co-defendants and Mersky, after  which the other

defendants were arrested.  Instead, Andino was apprehended on

November 26,  1991, when  United States Marshals  executed an

arrest warrant  for Andino  in Catalina,  Puerto Rico.   Upon

arriving  at Andino's home, the marshals were met at the door

by   appellant's  brother,  Cuco  Andino-Figueroa,  whom  the

marshals initially mistook for  appellant.  When the marshals

told  the brother  that they  had a  warrant from  Boston for

narcotics offenses,  appellant entered the  room and shouted,

"I'm the one you are looking for.   I'm the guilty one.  He's

never been to Boston.  I'm the one that's been to Boston."  

     Prior  to  trial, Andino  filed  a motion  in  limine to
                                                          

preclude testimony  as to his  spontaneous confession.   At a

hearing, Andino argued that the confession should be excluded

because it would guarantee conviction.  Construing this as an

argument under Fed. R. Evid.  403, the district court  denied

the motion  on the ground  that the confession  was "strongly

probative of  [Andino's] knowledge  and his intent,"  and was

"not  unfairly  prejudicial."   Andino  now  argues that  the

district court failed to  adequately consider the prejudicial

impact of the confession in striking the Rule 403 balance.

     The  district  court's  wide  latitude  in admitting  or

excluding  evidence  under  Rule  403  is  well  established.

Daigle v. Maine Medical  Center, Inc., 14 F.3d 684,  690 (1st
                                     

                             -5-

Cir.  1994).   The district  court found--and  we agree--that

Andino's  outburst  "shows  knowledge  on  the  part  of  the

defendant . .  . that a particular  crime involving narcotics

was the subject of the arrest, and it took place  in Boston."

The admission  has special  importance since at  trial Andino

argued that the government  had arrested the wrong man.   The

damage done to the defense is not a basis for exclusion;  the

question under Rule 403 is "one of `unfair' prejudice--not of

prejudice alone."   United States v. Moreno Morales, 815 F.2d
                                                   

725, 740 (1st Cir. 1987).

     We turn next  to a hearsay issue.  At  trial, Mersky was

allowed, over Andino's objection,  to testify that a landlord

had  given federal  drug agents a  rent receipt  showing that

Andino  rented a  room at  6 Michigan  Avenue in  Dorchester,

Massachusetts.   That address was shown at trial to have been

a center of  the conspiracy.  Andino argued both at trial and

on appeal that he was prejudiced by any reference to the rent

receipt--which, he contends, was "blatant hearsay" and should

not have been admitted.

     Although the government might  have argued that the rent

receipt itself was not  hearsay, cf. Fed. R. Evid.  801(a) (a
                                    

"statement"  is  an  oral  or  written  "assertion"),  it  is

apparently willing to  treat the testimony in  question as if

it were a report of what  the landlord said orally to the DEA

agents.  But  the government insists  that the testimony  was

                             -6-

not  elicited  or used  for purposes  of proving  that Andino

actually  lived at 6 Michigan  Avenue.  Rather,  it says that

the  testimony was brought out on redirect merely in order to

explain that Mersky had some colorable reason--whether or not

correct--for attaching Andino's name  to the description  she

furnished to the marshals in Puerto Rico.

     This   redirect  was  important,  the  government  says,

because during  the drug deals, about  which Mersky testified

at  length, she had  known Andino only as  "Bruno" and had no

knowledge of his real name.   On cross-examination of Mersky,

Andino's  defense  counsel  had  brought out  this  fact;  he

suggested in further questions  that Mersky's description  of

Bruno,  given to the marshals  in Puerto Rico,  did not match

Andino's appearance  in the  courtroom; and arguably  he left

the impression through his questions that there was something

suspicious in  the  unexplained appearance  of Andino's  real

name in the information given to the marshals.

     It is quite true  that an out-of-court statement is  not

hearsay if it  is used  only to show  that the statement  was

made  and that the  listener heard the words  uttered.  See 6
                                                           

Fed. R.  Evid. 801(c)  (hearsay is an  out-of-court statement

offered "to prove  the truth  of the matter  asserted").   We

have no  doubt that it  was on this theory  that the district

judge  overruled the  hearsay  objection, saying  that Mersky

"doesn't know whether it is true or not [that Andino lived at

                             -7-

6 Michigan Avenue].  She just knows how she found out.  It is

not offered for the truth  of the matter, just how  she found

out."   Whether or not  there is still  an underlying hearsay

problem is  an issue that could be  debated at length; and in

some  measure   it  might  depend  on   matters  not  clearly

developed:    exactly  what  the  landlord  said;  just  what

information  was relayed to Mersky  and then to the marshals;

and  precisely what  inference  the government  is aiming  to

refute.

     We see no reason to engage in these speculations because

the admission of this evidence was patently harmless.  Mersky

had  dealt  face  to  face with  "Bruno"  on  four  different

occasions.   Her ability to identify Andino as Bruno could be

easily  tested in  the courtroom  and was  in fact  tested on

cross-examination.   The jury  was also apprised  of Andino's

virtual confession at the time of his arrest ("I'm the guilty

one."),  and his  further  incriminating statement  after his

arrest (Andino told  his father that there was  no point in a

removal hearing since "[Mersky]  would come over and identify

me").  The alleged hearsay did not alter the outcome.

     Andino next claims that  there was insufficient evidence

to support  his conviction for the May  30, 1991, transaction

in which other defendants sought to sell 506 grams of cocaine

base  to Mersky.    The parties  agree  that Andino  was  not

present at this transaction.  At trial, the government argued

                             -8-

that Andino was liable under Pinkerton  v. United States, 328
                                                        

U.S.  640 (1946).  Pinkerton  permits a defendant  to be held
                            

liable  for actions  committed  by a  co-conspirator if  that

crime is in  furtherance of the  conspiracy and is  committed

while the defendant  is a member of  the conspiracy.   Id. at
                                                          

328.  See United States v. O'Campo,  973 F.2d 1015, 1021 (1st
                                  

Cir. 1992).

     In  this court, Andino  does not dispute  the theory but

argues that the evidence at trial was so thin that his motion

for judgment of  acquittal should  have been  granted.   This

requires Andino  to "bear  the heavy burden  of demonstrating

that no reasonable jury could  have found [him] guilty beyond

a reasonable  doubt."  United States v.  Innamorati, 996 F.2d
                                                   

456, 469 (1st Cir.), cert. denied, 114 S. Ct. 409 (1993).  We
                                 

review the  evidence  in  the  light most  favorable  to  the

government,  "drawing all plausible  inferences in  its favor

and resolving all credibility determinations in line with the

jury's verdict."  Id.
                     

       Under Pinkerton,  the government was required to prove
                      

that the May 30 transaction was carried out by members of the

conspiracy, in furtherance  of the conspiracy, and  at a time

when Andino was still a member of the conspiracy.  Andino has

not  claimed a  lack of  evidence to  support his  conspiracy

conviction.   Nor does he dispute that the May 30 transaction

was  in furtherance of the  conspiracy.  But  he does dispute

                             -9-

that he was still a member as of May 30, 1991, arguing in his

brief that  he  "disappeared entirely  from the  Government's

radar  screen" after  May 16,  1991.   In fact,  there is  no

evidence in  the record concerning his  activities after that

date until his arrest in Puerto Rico on November 26, 1991.

     A  "`mere  cessation of  activity  in  furtherance of  a

conspiracy does  not constitute withdrawal.'"   United States
                                                             

v. Nason, 9 F.3d  155, 162 (1st Cir. 1993), cert. denied, 114
                                                        

S. Ct.  1331 (1994) (quoting  United States v.  Juodakis, 834
                                                        

F.2d 1099, 1102 (1st Cir. 1987)).  To withdraw, a conspirator

must  take  some  affirmative  action "either  to  defeat  or

disavow the  purposes of the conspiracy."  Juodakis, 834 F.2d
                                                   

at 1102.  Typically,  we have required "evidence either  of a

full  confession to  authorities  or a  communication by  the

accused  to his  co-conspirators  that he  has abandoned  the

enterprise  and its  goals."   Id.   Even if a  very extended
                                  

lapse  of time might  be sufficient to  infer withdrawal, the

two-week interval in this case is not enough.

     B.  Martinez

     Appellant Martinez also challenges his conviction.  Both

Martinez  and  his  co-defendant,  Gerardo  Delgado,  pleaded

guilty  on October  30, 1985, in  Connecticut state  court to

possession  of cocaine  with intent  to distribute  it.   The

government  introduced these  convictions  at trial  over the

defendants'  objections  in   order  to  show,   inter  alia,
                                                            

                             -10-

"knowledge  and intent in a common scheme or plan."  Martinez

now asserts that "[a]dmission  of evidence of Martinez' prior

conviction impermissibly prejudiced his defense," but adds no

explanation  to this one-line allegation.  "[I]ssues adverted

to in a  perfunctory manner, unaccompanied by  some effort at

developed argumentation,  are deemed waived."   United States
                                                             

v. Zannino, 895 F.2d 1, 17 (1st Cir.), cert. denied, 494 U.S.
                                                   

1082 (1990).

     Martinez also says that the evidence was insufficient to

support his  convictions for conspiracy,  and for  possession

with  intent to distribute on May 30, 1991.  The government's

evidence on both  counts arises from the  May 30 transaction.

Martinez was first spotted at about 6:50 p.m. that evening by

a state police officer  who saw Martinez walking up  and down

the  street   outside  SkipJack's  restaurant   in  Brookline

Village.   Mersky,  who  had been  told  by Delgado  to  wait

outside SkipJack's at 7:30 p.m.  in order to purchase  drugs,

testified  that Martinez  greeted her  there and  then walked

away.

     Shortly   thereafter,   Delgado   contacted  Mersky   by

signaling  her beeper.  When Mersky called Delgado from a pay

phone, Mersky was told to meet Paulita Cadiz, who (along with

Lazaro Delgado) accompanied her to a  blue-colored Oldsmobile

occupied  by Martinez and a female  juvenile.  Martinez, then

sitting in the driver's seat, pushed a large piece of luggage

                             -11-

located on the passenger-side floor toward Lazaro Delgado and

assisted him in opening it.  The bag contained numerous vials

of  cocaine base.    Mersky took  the  bag and  walked  away,

announcing that she was "going to get the money."

     As Mersky walked away, she signalled to two officers who

were waiting in an  unmarked car nearby.  The  officers, each

of  whom  were  wearing   raid  jackets  marked  with  police

insignia, got out  of their  car and turned  toward the  blue

Oldsmobile, displaying firearms and shouting "police."   Both

officers testified  that Martinez then  threw the  Oldsmobile

into reverse and backed up Brookline Avenue at a high rate of

speed.  After crashing  into another unmarked police cruiser,

Martinez put the car back in forward gear and sought to flee.

He was eventually stopped and arrested.

     The testimony was ample to convict Martinez on  both the

conspiracy and substantive distribution counts.  A reasonable

jury  could  have  inferred  that  Martinez  was   conducting

counter-surveillance  when  he  was  first  observed  outside

SkipJack's.    Martinez  was  the  only  adult  in  the  blue

Oldsmobile  along with  the  suitcase  containing the  drugs;

since he then pushed the drugs over to Lazaro Delgado to give

to Mersky, the jury could reasonably have found that Martinez

had  possessed the  drugs.2   His  intent  to distribute  can

                    

     2Martinez argues  that he  could not have  possessed the
drugs  because  he  did not  have  sole  access  to the  bag.
Exclusive access is not a prerequisite to possession; indeed,

                             -12-

likewise  be  inferred  from this  same  event  and from  his

participation  in the  overall transaction.   The  attempt to

flee further corroborates his guilt.

     The jury was also entitled to infer that Martinez agreed

to cooperate with his alleged co-conspirators in carrying out

the  transaction.  The many  steps of the  dance performed by

the  participants indicate careful planning and coordination,

and  Martinez's own multiple  roles--lookout, initial contact

with Mersky,  guardian of  the drugs--do  not  look like  the

unplanned actions of an unwitting victim who was merely along

for the ride.  In any  event, the evidence was sufficient for

a reasonable jury to convict  Martinez on both the conspiracy

and substantive distribution counts.

     C.  Quinones

     The  remaining  appellant is  Quinones.   The government

alleged at trial that Quinones was Delgado's partner in their

drug distribution  activities.  Quinones now  argues that the

district  court erred in instructing the jury on the issue of

liability for crimes committed  by co-conspirators under  the

Pinkerton doctrine.  As already explained, Pinkerton allows a
                                                    

defendant  to be held criminally liable for the acts of a co-

conspirator carried out in furtherance of the conspiracy at a

time when the defendant  is a member of the  conspiracy, even

                    

"joint possession"  is one of the  possibilities mentioned in
the  standard charge.  See, e.g., United States v. Maldonado,
                                                            
23 F.3d 4, 6-7 (1st Cir. 1994).

                             -13-

though  the defendant  himself did  not participate  in those

acts.  See 328 U.S. at 645-48.
          

     Quinones  argues that  the  district court  should  have

emphasized  the jury's  obligation  to find  each element  of

Pinkerton beyond  a reasonable doubt.   Although the district
         

court gave a separate reasonable doubt instruction applicable

to  the  entire  case,  Quinones  cites  us  to  the  Seventh

Circuit's  decision in  United States  v. McKenzie,  922 F.2d
                                                  

1323, 1330 (7th Cir.),  cert. denied, 112 S. Ct.  163 (1991),
                                    

which suggested that a complete Pinkerton instruction  should
                                         

inter alia  "`advise jurors  that the government  [bears] the
          

burden  of proving  .  .  .  all  elements  of  the  powerful

Pinkerton doctrine . . . beyond a reasonable doubt'" (quoting
         

United  States v.  Elizondo, 920  F.2d 1308,  1317 (7th  Cir.
                           

1990)).

     This  court "evaluate[s]  [a] challenged  instruction in

the context of the  overall charge."  E.g., United  States v.
                                                          

Vavlitis,  9 F.3d 206, 212  (1st Cir. 1993).   Similarly, the
        

Supreme  Court in   Cupp  v. Naughten,  414 U.S.  141, 146-47
                                     

(1973), referred to "the  well-established proposition that a

single  instruction to a jury may not be judged in artificial

isolation, but must be  viewed in the context of  the overall

charge."    Here, the  district  court  began its  charge  by

stating  that the  government was  obligated to  "prove every

element  of every  offense  beyond a  reasonable doubt,"  and

                             -14-

referred  to that burden of  proof over a  dozen times during

the course of its instructions.

     Pinkerton may  be a powerful  doctrine, but there  is no
              

reason  to think that the jury is especially likely to forget

the general instruction on reasonable  doubt when it comes to

applying  Pinkerton.  We have no  intention of constructing a
                   

special requirement that reasonable doubt be mentioned again,

after an adequate general  statement, in relation to selected

elements  in an offense or  theory of liability.   Indeed, in

United States v. Mount, 896 F.2d 612, 623-24 (1st Cir. 1990),
                      

cert. denied, 114 S. Ct. 415 (1993), we rejected just such an
            

argument pertaining  to the  district court's instruction  on

interstate transportation of stolen property.

                      II.  THE SENTENCES

     Appellants  also  challenge  numerous aspects  of  their

sentences under  the  federal sentencing  guidelines, and  we

consider  each  appellant's  claims  in  turn--starting  with

Delgado,  the  alleged ringleader  of  the drug  distribution

conspiracy.

     A.  Delgado

     At Delgado's sentencing, the district court began with a

base offense  level of  36 in  light of  the amount  of drugs

involved, added one level because drug  distribution activity

took place in proximity  to a school, U.S.S.G.    2D1.2, then

added four levels  for Delgado's leadership role.  U.S.S.G.  

                             -15-

3B1.1(a).  The court denied Delgado a two-level reduction for

acceptance  of  responsibility,  see  U.S.S.G.    3E1.1,  and
                                    

placed  him in criminal history  category II based  on a 1985

Connecticut  conviction for possession of cocaine with intent

to  distribute.   The  court then  sentenced  Delgado to  360

months, the bottom of the resulting guideline range.

     On appeal,  Delgado first contests the  district court's

denial  of  a  reduction  for acceptance  of  responsibility.

Shortly after  his arrest, Delgado made a statement to police

officers in which, he asserts, he accepted responsibility for

his crime.   In that statement, according to  police reports,

Delgado acknowledged that  he had called someone  who had the

cocaine  in order  to set  up the  transaction, and  had then

called Special  Agent Mersky to  arrange a meeting.   Despite

this admission,  Delgado subsequently pled not  guilty to the

indictment and went to trial.

     Delgado now  contends that the district  court failed to

consider his post-arrest statement  and refused to reduce his

offense level  under section  3E1.1 solely as  punishment for

invoking his constitutional  right to a trial.   The district

court addressed the statement  made by Delgado, but concluded

in  substance  that   it  was  not   a  full  acceptance   of

responsibility.   Indeed, while  the statement  admitted that

Delgado played  some role in  the offense, it  downplayed his

own role and  asserted that some  unnamed individual was  the

                             -16-

true source of the  drugs.  The court's decision  is reviewed

only  for  clear error,  and  no  such  error occurred  here.

United  States v.  Donovan,  996 F.2d  1343,  1346 (1st  Cir.
                          

1993); U.S.S.G.   3E1.1, application note 5. 

     At sentencing,  the district  court said that  Delgado's

failure to plead guilty was an important factor in the denial

of credit.   This  is consistent  with the guidelines,  which

provide  that  "[c]onviction  by  trial   .  .  .  does   not

automatically  preclude a  defendant  from consideration  for

such  a  reduction" but  ordinarily  the  adjustment "is  not

intended to apply to  a defendant who puts the  government to

its burden of proof at trial by denying the essential factual

elements of  guilt, is convicted, and only  then admits guilt

and expresses  remorse."  U.S.S.G.    3E1.1, application note

2.3

     Obviously, the guideline, consistent  with pre-guideline

practice, means that a defendant who declines to plead guilty

reduces the chance of  a lightened sentence.  But  "not every

burden on the  exercise of  a constitutional  right, and  not

                    

     3There  are  exceptions;  the   guidelines  specifically
mention one  who "litigates  to preserve  issues that  do not
relate to factual  guilt . .  . ."   Id.   Delgado argues  on
                                        
appeal  that  he  failed  to  plead  guilty  to  avoid  being
immunized and  forced to testify against  his brother, Lazaro
Delgado, on  behalf of  the government.   Since  neither this
argument  nor  any  evidence  in  support  of  it  were  ever
presented  to the  district  court, we  do  not consider  the
claim.   United States v.  Dietz, 950 F.2d  50, 55 (1st  Cir.
                                
1991).

                             -17-

every pressure or  encouragement to  waive such  a right,  is

invalid."   Corbitt v. New  Jersey, 439 U.S.  212, 218 (1978)
                                  

(possibility of a lesser sentence through a plea bargain does

not unconstitutionally burden the right to stand trial).  The

guidelines "merely codify a tradition of leniency [for guilty

pleas] and are not an impermissible burden on the exercise of

constitutional  rights."   United States  v. Uribe,  891 F.2d
                                                  

396, 400 (1st Cir. 1989), cert. denied, 495 U.S. 951 (1990).
                                      

     Delgado   also   objects   to   the   district   court's

consideration,  in calculating his criminal history category,

of a prior  Connecticut conviction for  unlawfully possessing

cocaine with intent to distribute.  At his sentencing hearing

in the  present case,  Delgado sought to  attack collaterally

the prior state conviction, asserting that his guilty plea in

that case was constitutionally  invalid.  The district court,

relying upon our decision in United States v. Paleo, 967 F.2d
                                                   

7  (1st Cir.  1992),  considered Delgado's  arguments on  the

merits  but   determined  that   the   guilty  plea   "passed

constitutional muster."

     After  Delgado's sentencing, Paleo  was greatly narrowed
                                       

by  United States v. Isaacs,  14 F.3d 106,  108-110 (1st Cir.
                           

1994), which  held that the sentencing  guidelines provide no

independent   authority  for   collateral  review   of  prior

convictions  used  in   calculating  a  defendant's  criminal

history   category.     Although  Isaacs   preserved  certain
                                        

                             -18-

exceptions  based  upon  the  Constitution  rather  than  the

guidelines, the Supreme Court  subsequently held in Custis v.
                                                          

United States, 114 S. Ct.  1732 (1994), that the Constitution
             

requires  collateral review  of  a prior  conviction used  to

enhance  a   defendant's  federal  sentence  only  where  the

defendant alleges  a complete  denial of his  Sixth Amendment
                             

right to counsel in the prior proceeding.

     Although  Custis considered collateral  attack under the
                     

Armed   Career  Criminal  Act   rather  than  the  sentencing

guidelines  themselves,  the constitutional  question  is the
                                           

same  in each  context.   Like Delgado  in the  present case,

Custis alleged that one of his prior convictions was procured

pursuant  to   a  guilty  plea  that  was   not  knowing  and

intelligent as  required by Boykin  v. Alabama, 395  U.S. 238
                                              

(1969).   The  Supreme Court  rejected this  argument, noting

that  "when  a guilty  plea is  at  issue, `the  concern with

finality served  by the  limitation on collateral  attack has

special force.'"  114  S. Ct. at 1738 (quoting  United States
                                                             

v. Timmreck, 441 U.S.  780, 784 (1979)).  Given Custis, we do
                                                      

not  reach the merits  of Delgado's challenge  to his earlier

conviction.

     B.  Andino

     We  turn now  to the  sentencing claims  of Andino.  The

district court began with a base offense level of 36, finding

that Andino was  responsible for 745.1 grams of cocaine base.

                             -19-

U.S.S.G.   2D1.1(c).   The court then deducted two  levels on

the ground  that  Andino  was  a  minor  participant  in  the

conspiracy, U.S.S.G.    3B1.2(b).   Given a  criminal history

category of I, the guideline range was 151 to 188 months, and

the  district court imposed a sentence of 151 months.  Andino

now asserts that the court erred in several respects, firstly

by attributing to him 506 grams of cocaine base sold by other

defendants to Mersky on May 30, 1991, when Andino was neither

present nor involved in the transaction.

     Individuals convicted of membership in a drug conspiracy

are held responsible at sentencing not only for "drugs [they]

personally handled or anticipated handling," but also, "under

the relevant conduct rubric, for drugs involved in additional

acts  that were  reasonably  foreseeable by  [them] and  were

committed in  furtherance of the conspiracy."   United States
                                                             

v. Sepulveda,  15 F.3d  1161, 1197 (1st  Cir. 1993).   In the
            

usual case, what is  foreseeable depends on the scope  of the

defendant's  agreement  with the  other  participants in  the

criminal enterprise.  United  States v. Garcia, 954  F.2d 12,
                                              

16 (1st Cir.  1992).  Accordingly, the district  court's task

was  to   determine  whether  the  May   30  transaction  was

reasonably  foreseeable  based  upon  the scope  of  Andino's

agreement with his  co-conspirators.  Our review  is only for

clear error. United States v. De la Cruz, 996 F.2d 1307, 1314
                                        

(1st Cir.), cert. denied, 114 S. Ct. 356 (1993).
                        

                             -20-

     The record leaves little  question that the May  30 sale

was the "natural progression of the earlier series of sales,"

Garcia, 954 F.2d at 16, and thus within the scope of Andino's
      

agreement with his  co-conspirators.  True,  the government's

evidence  did not mention Andino  after May 16,  but there is

also  no evidence  that  he affirmatively  withdrew from  the

conspiracy.  Nor is it conclusive that the May 30 transaction

was larger than earlier  transactions.  In fact, co-defendant

Quinones told Special Agent  Mersky that the conspirators had

other customers who bought in larger quantities than she did.

     Next, the district  court found that Andino was  a minor

participant  in the  conspiracy and  accordingly  reduced his

base offense  level by  two  levels, pursuant  to U.S.S.G.   

3B1.2(b).  In so doing,  the court rejected Andino's argument

that he was entitled to an even larger reduction as a minimal

participant.   See U.S.S.G.    3B1.2(a).   Andino now  renews
                  

this argument on appeal, stressing his unfamiliarity with the

English  language  and his  absence  at  the group's  largest

transaction on May 30, 1991.

     The  guidelines  note  that  the  "minimal  participant"

reduction should  be "used  infrequently," U.S.S.G.    3B1.2,

application  note  2, and  the  defendant has  the  burden of

showing his entitlement  to the reduction.   United States v.
                                                          

Figueroa,  976 F.2d 1446, 1461 (1st  Cir. 1992) cert. denied,
                                                            

113 S.  Ct. 1346  (1993).   Here, Andino  was involved  in at

                             -21-

least  four cocaine  transactions and  performed a  number of

different functions, including guarding the drugs, conducting

counter-surveillance, and delivering  cocaine base to Special

Agent Mersky.   Compare U.S.S.G.   3B1.2,  application note 2
                       

(minimal  participant "played  no other  role .  . .  than to

offload part  of  a  single  marijuana shipment,"  or  was  a

courier in "a single smuggling transaction").  We sustain the

district  court's  finding  that  Andino's role  was  "minor"

rather than something less.

     Last,  the  guidelines distinguish  dramatically between

cocaine and cocaine  base (or "crack"), treating one  gram of

the  latter as  the equivalent  of 100  grams of  the former.

Andino argues that the  government's trial evidence failed to

distinguish   clearly  between  cocaine   base  and  ordinary

cocaine.  He also  claims that the jury's finding  of cocaine

base  rests upon "untrustworthy  evidence and faulty although

well intended instruction[s]" by the court.

     Whether the substance distributed was cocaine or cocaine

base  was a matter to be determined  by the district judge at

sentencing, not the  jury. United States v. Barnes,  890 F.2d
                                                  

545, 551 n.6  (1st Cir.  1989), cert. denied,  494 U.S.  1019
                                            

(1990).   Under 21 U.S.C.    841(a), the jury need  only find

that  the defendant distributed  a substance  containing some

mixture of  cocaine as defined  in schedule  II. Barnes,  890
                                                       

F.2d at 551  n.6; see 21  U.S.C.    812,  841(a).  On  appeal
                     

                             -22-

from the sentence, we  need only review the  district court's

sentencing  determination  that  the  substance  involved was

cocaine base. Barnes, 890 F.2d at 551 n.6.
                    

     Andino's argument is directed  to the trial testimony of

DEA   chemist  Florence   Wong,  who   testified   about  the

differences  between  ordinary   cocaine  and  cocaine  base.

Although Wong did  misspeak at one  point in the  transcript,

her  overall testimony was  not confusing or  misleading:  it

was that ordinary cocaine (cocaine hydrochloride) and cocaine

base  are distinct  forms of  the drug,  and that  the latter

commonly goes by  the street  name of "crack";  that she  had

tested samples  from each  of the transactions  involving the

defendants;  and that  each  sample  contained cocaine  base.

Corroborated  by   recorded   statements  of   Andino's   co-

defendants, and  by field  tests conducted by  Mersky, Wong's

testimony  amply supports the  district court's  finding that

the defendants distributed cocaine base.

     C.  Martinez

     In sentencing Martinez, the  district court began with a

base offense level of  36 based on its finding  that Martinez

was accountable for  506 grams  of cocaine base.   The  court

granted  a  four-level  reduction  (because  Martinez  was  a

minimal  participant in the  conspiracy, U.S.S.G.   3B1.2(a))

and added two levels (because Martinez had obstructed justice

by  recklessly  endangering others  in  fleeing from  police,

                             -23-

U.S.S.G.   3C1.2).  Martinez's total offense level of 34, and

his  criminal history  category  of II,  yielded a  guideline

range of 168 to 210 months' imprisonment.  But because of his

prior Connecticut drug conviction,  Martinez was subject to a

mandatory  minimum  sentence  of  240  months,  21  U.S.C.   

841(b)(1)(A); U.S.S.G.    5G1.1(b), which the  district judge

imposed.

     On appeal, Martinez makes three claims of error.  First,

although he  was present  at the  May  30, 1991  transaction,

Martinez complains on appeal that he  could not have foreseen

that there  would  be 506  grams  of cocaine  base  involved.

Martinez did not raise this  argument below.  Accordingly our

review  is  only for  plain error,  Fed.  R. Crim.  P. 52(b);

United  States v. Colon-Pagan, 1 F.3d 80, 81 (1st Cir. 1993),
                             

a difficult  assertion here  since foreseeability is  a fact-

based inquiry.

     We  have  already  determined  that  the  evidence   was

sufficient  to establish  that Martinez  was a member  of the

conspiracy  who  joined in  its general  objectives.   It was

entirely  reasonable  to  infer  that Martinez  knew  that  a

substantial quantity of drugs were to  be sold on May 30.  As

we  held in  De  la Cruz,  "[a]  defendant who  conspires  to
                        

transport  for distribution  a large  quantity of  drugs, but

happens not to know the precise amount, pretty much takes his

chances  that  the amount  actually  involved  will be  quite

                             -24-

large."  996 F.2d at 1314. 

     Second,   Martinez  claims  that   there  is  an  unfair

disparity between his sentence and those meted out to his co-

defendants.  We have held that at least in the ordinary case,

"[t]he  guidelines do  not  require the  sentencing court  to

consider related cases or  to justify a sentence in  terms of

the punishment meted out to co-defendants."  United States v.
                                                          

Font-Ramirez, 944 F.2d 42, 50 (1st Cir.  1991), cert. denied,
                                                            

112  S. Ct. 954 (1992).   In this  case, moreover, Martinez's

sentence  was  wholly  determined  by  a  mandatory   minimum

prescribed by statute.  See 21 U.S.C.   841(b)(1)(A).
                           

     Martinez's  final  claim  is  a  vague  and  perfunctory

collection of  challenges to  the validity of  the sentencing

guidelines under  the  heading "Sentencing  is  Impermissibly

Draconian."   Martinez  does  not  explain in  what  way  the

sentencing  guidelines  are  inflexible  or  what  mitigating

circumstances they have failed  to reflect in this case.   In

any event, Martinez's sentence  was determined by a statutory

minimum sentence for  defendants in Martinez's  circumstances

and   any  alleged   inflexibility  in   the  guidelines   is

irrelevant.

     Martinez's   further  argument--that   the  Constitution

provides  a right  to  "punishment that  fits the  crime"--is

resolved by  Harmelin v. Michigan,  111 S.  Ct. 2680  (1991).
                                 

That  decision upheld, against a proportionality challenge, a

                             -25-

state regime  imposing a  mandatory sentence of  life without

parole for  possessing more  than 650 grams  of cocaine.  See
                                                             

also United States  v. Lowden,  955 F.2d 128,  131 (1st  Cir.
                             

1992) (upholding,  under Harmelin, a sentence  of seven years
                                 

for  distribution  of  7.7  grams of  LSD).    Conspiracy  to

distribute  a large  quantity  of cocaine  base is  a serious

crime, the more so when committed by a prior offender.  Given

Harmelin,  we  cannot   say  that  Martinez's  sentence   was
        

unconstitutionally excessive.

     D.  Quinones

     In sentencing Quinones, the  district court began with a

base offense  level of  36, based  on a  finding that  he was

accountable  for 896.2 grams of cocaine base.  The court then

added three levels on account of Quinones' managerial role in

the conspiracy.  U.S.S.G.   3B1.1(b).  The  resulting offense

level of  39, along with Quinones'  criminal history category

of IV,  yielded a guideline range of 360 months to life.  The

court  sentenced  Quinones  at  the  bottom  of  that  range.

Quinones now challenges the  district court's decisions as to

his role  in the offense and the amount of drugs for which he

should be held accountable.

     Section 3B1.1(b)  of the guidelines provides  that "[i]f

the  defendant  was  a  manager or  supervisor  (but  not  an

organizer or leader) and  the criminal activity involved five

or more  participants  or was  otherwise extensive,  increase

[the base offense  level] by  3 levels."   Quinones does  not

dispute that  the conspiracy in  this case involved  at least

five participants; he argues, however, that he did not play a

managerial role.  The government had the burden at sentencing

of  proving by a preponderance of the evidence that an upward

adjustment was  warranted.  United States v.  Ortiz, 966 F.2d
                                                   

707,  717  (1st Cir.  1992), cert.  denied,  113 S.  Ct. 1005
                                          

(1993).   Despite Quinones'  assertion that he  was merely "a

foot  soldier" like Martinez and  Andino, we think that there

                             -27-

was  sufficient  evidence  to  sustain the  district  court's

finding.   Special Agent  Mersky testified that  Delgado, the

acknowledged   ringleader   of  the   conspiracy,  introduced

Quinones  to her  as his "partner."   Moreover,  the district

court found that Quinones  had exercised supervisory  control

over  Andino at the abortive transaction on May 3.  Quinones'

action  in renegotiating the price  of the drugs  at the more

successful  May 6  transaction  also suggests  a position  of

authority.

     Quinones rightly  points out  that one can  imagine more

than  one explanation for all  of these events,  but we think

that the view taken by the district court is not implausible.

United  States v. Savoie, 985  F.2d 612, 616  (1st Cir. 1993)
                        

(sentencing court's choice between two plausible views of the

record cannot  be clearly erroneous).   Additionally, we have

said  that  "[m]anagerial  status  may  attach  if  there  is

evidence that a defendant, in committing the crime, exercised

control over, or was otherwise responsible for overseeing the

activities  of, at  least  one  other  person."    Id.    The
                                                      

imposition  of the  sentence enhancement  here was  not clear

error.

     Like  Andino, Quinones  was not present  at the  May 30,

1991 transaction and thus claims that he should not have been

held  accountable for the 506 grams  of cocaine base involved

in  that  transaction.   As we  have  noted above,  there was

                             -28-

considerable  evidence  at  trial  that   Quinones  played  a

prominent  role in  the conspiracy,  making it  reasonable to

infer that Quinones was well-acquainted with the scope of the

group's activities  and plans.  Quinones does  not argue that

he  had  withdrawn  from  the conspiracy  prior  to  May  30.

Accordingly,  we uphold  the  district court's  determination

that Quinones was  accountable for the full amount of cocaine

base distributed over the life of the conspiracy.

     Appellants' convictions and sentences are affirmed.
