(dissenting).
I respectfully dissent. This decision seems to me to be a serious blow to efficient law enforcement not required by the Fourth Amendment. The search and seizure, I think, were reasonable as incidental to the arrest of appellant, and if not, then most certainly as incidental to the arrest of his co-defendant, Johney Nunnally.
Before entering upon the appellant’s premises, the officers had no information that there was a still in his barn, and hence they had no intention of searching the barn, but were headed direct for a search of the woods.1 When within 30 to 60 feet of the barn, Officers Boone and Ferguson smelled the distinctive odor2 of cooking mash (R. 25, 54), saw the black garden hose running beneath the edge of the barn, heard noises “like a can or drum hit the ground” and “a noise that sounded like somebody running” (R. 25). Boone and Ferguson immediately turned and ran to the barn (R. 54, 136), but before they could effect a capture, one man escaped. (R. pp. 42, 83, 103). Promptly upon entering the barn, the officers placed appellant’s co-defendant, Johney Nunnally under arrest (R. 104). They later found Fred Walker, appellant’s brother, hiding in a corn *452crib in the barn (R. 97, 149), but did not arrest him.
Appellant and Johney Nunnally were jointly indicted in four counts, each charging the commission of a felony as follows:
“Count One: Possession of unregistered still, 26 U.S.C.A. § 2810.
“Count Two: Carrying on business of distiller without bond, 26 U.S.C.A. § 2833.
“Count Three: Making mash, 26 U.S.C.A. § 2834.
“Count Four: Possession of 12 gallons of unstamped whiskey, 26 U.S.C.A. § 2803 (R. 1-2).”
In the district court, appellant brought out the fact that Johney Nunnally had pleaded guilty. (R. 104, 150.)
The district court, after a full and fair hearing, overruled the defendant’s motion to suppress evidence, and in so doing made a finding of some facts, which finding is fully sustained by the record.3
The Fourth Amendment protects “The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures” (emphasis supplied). It is settled that “houses” includes not only dwellings but offices and places of business. Gouled v. United States, 255 U.S. 298, 305, 41 S.Ct. 261, 65 L.Ed. 647. On the other hand, as said by Mr. Justice Holmes in Hester v. United States, 265 U.S. 57, 59, 44 S.Ct. 445, 446, 68 L.Ed. 898 :
“ * * * the special protection accorded by the Fourth Amendment to the people in their ‘persons, houses, papers and effects,’ is not extended to the open fields. The distinction between the latter and the house is as old as the common law. 4 Bl. Comm. 223, 225, 226.”
See, also, Edwards v. United States, 10 Cir., 206 F.2d 855, 856.
In the same opinion, Mr. Justice Holmes further observed, “It is obvious that even if there had been a trespass, the above testimony was not obtained by an illegal search or seizure.” 265 U.S. at page 58, 44 S.Ct. at page 446. As said by the Fourth Circuit in Janney v. United States, 206 F.2d 601, 604, “The fact that the officers were trespassers on the defendant’s property was thought to be immaterial.” In Koth v. United States, 16 F.2d 59, 61, the Ninth Circuit said: “The fact that the officers may have been trespassers does not exclude the evidence after what they saw, heard and smelled.”4 In United States v. Rogato, *453D.C.M.D.Pa., 39 F.2d 171, 175, the Court said: “Nor does the special protection accorded by the Fourth Amendment extend to the open driveways on each side of the building, or the open space in the rear of the building.”
Neither the Supreme Court nor any Federal Court of Appeals has ever held that the word “houses” includes open land even within the curtilage of a dwelling. The state courts of Kentucky and of Mississippi, which have held that the land within the curtilage is protected, based their decisions on the word “possessions” appearing in the Constitutions of those States,5 but not contained in the Fourth Amendment. It will be observed that in the Supreme Court ease of Hester v. United States, supra, the officers were concealed prior to the search only 50 to 100 yards from the dwelling. In Martin v. United States, 5 Cir., 155 F.2d 503, 505, Judge Lee speaking for this Court said: “Enclosed or unenclosed grounds or open fields around their houses are not included in the prohibition.”
Under the facts of this case, I doubt the correctness of the holding that, “this barn was a part of the curtilage,” but I am not convinced that the “curtilage” test is the right one. It would imply protection to the open spaces of the lot, and such an extreme position cannot soundly be maintained. It would imply, also, that buildings outside the curtilage are not within the protection of the Fourth Amendment, and, while I am aware of cases so holding,6 I can see no reason why a farmer should be afforded less protection in the barn where he actually does business, whether located within the curtilage or not, than is accorded a city dweller in his office. A more accurate statement of the rule, I think, was made by the Fourth Circuit in the recent case of Janney v. United States, supra, 206 F.2d at page 603:
“We bear in mind that the protection of the Amendment extends not only to the dwelling house of a defendant but also to the structures used by him in connection with his home or his place of business.”
While I thus disagree with the “curti-lage” test employed by my brothers, I am in accord with their conclusion that appellant’s barn was afforded the protection of the Fourth Amendment. When, however, it comes to a question of degree, of “when the right of privacy must reasonably yield to the right of search”,7 it seems to me that any attempt to equate a man’s barn with his dwelling must lower the dignity of the latter, and that his home more appropriately meets the description of his castle, of his cottage into which even the King’s men may not enter. In United States v. Rabinowitz, 339 U.S. 56, 64, 70 S.Ct. 430, 94 L.Ed. 653, the Supreme Court recognized that even though a structure came within the protection of the Amendment, the character of the place was properly to be considered in determining whether the search was reasonable. In our own recent case of Drayton v. United States, 205 F.2d 35, 36, this Court recognized that:
“Although stricter requirements of reasonableness may apply where *454a dwelling is being searched, compare Davis v. United States, 328 U.S. 582, (592), 66 S.Ct. 1256, 90 L.Ed. 1453; Matthews v. Correa, 2 Cir., 135 F.2d 534, 537, * * * ”
That language appears to have been taken directly from Harris v. United States, 331 U.S. 145, 151, footnote 15, 67 S.Ct. 1098, 91 L.Ed. 1399.
From my brothers' conclusion that the search was an “unreasonable” one, I respectfully but vigorously dissent.
“What is a reasonable search is not to be determined by- any fixed formula. The Constitution does not define what are ‘unreasonable’searches and, regrettably, in our discipline we have no ready litmus-paper test. The recurring questions of the reasonableness of searches must find resolution in the facts and circumstances of each case. Go-Bart Importing Co. v. United States, 282 U.S. 344, 357, 51 S.Ct. 153, 158, 75 L.Ed 374. Reasonableness is in the first instance for the District Court to determine.” United States v. Rabinowitz, supra, 339 U.S. at page 63, 70 S.Ct. at page 434.
That case overruled Trupiano v. United States, 334 U.S. 699, 68 S.Ct. 1229, 92 L.Ed. 1663, to the extent that Trupi-ano required a search warrant solely upon the basis of the practicability of procuring it, but we held in Rent v. United States, 5 Cir., 209 F.2d 893, 899, that the practicability of procuring a search warrant is still one of the factors to be considered in deciding whether a search without a warrant is reasonable. My brothers think that there was time to procure a search warrant because the officers were “present and able to place guards at all exits.” To me this case does not present so leisurely a picture.8 Before they could do so, one of the culprits escaped, another hid in the corn crib, and appellant’s co-defendant Johney Nunnally was attempting to escape. Further, what were such guards to do ? Were they to stand helplessly by while the operators of the illicit still fled? If they had sufficient information on which to confine the occupants of the bam to that structure or to arrest them as they fled, then it seems to me that they had authority to enter the barn for that purpose. My brothers say, however, that “no removal of the contraband was possible.” Even that does not seem to me to be so, for pouring illicit whiskey or liquid mash down an underground drain is perhaps a common experience suffered by law enforcement officers.
The Rabinowitz case, as well as a long line of cases, recognizes “The right without a search warrant contemporaneously to search persons lawfully arrested while committing crime and to search the place where the arrest is made * * Agnello v. United States, 269 U.S. 20, 30, 46 S.Ct. 4, 5.
My brothers say, “The arrest of appellant followed and did not precede the search and was based upon the result of the illegal search." I do not think so, as I will point out in a moment. However, assuming that to be so, then what about the arrest of Johney Nunnally? He has never even questioned the validity of his *455Arrest, but to the contrary, has pleaded guilty. If the search was lawful as incidental to the arrest of appellant’s co-defendant, it could hardly be unlawful as to the appellant. See United States v. Jeffers, 342 U.S. 48, 51, 52, 72 S.Ct. 93, 96 L.Ed. 59; McDonald v. United States, 335 U.S. 451, 454, 69 S.Ct. 191, 93 L.Ed. 153; It seems to me, as said by Mr. Justice Black, concurring in Wolf v. Colorado, 338 U.S. 25, 39, 40, 69 S.Ct. 1359, 1367, 93 L.Ed. 1782, “* * * that the federal exclusionary rule is not a command of the Fourth Amendment but is a judicially created rule of evidence which Congress might negate.” It is a rule that evidence gained by the Government’s own wrong shall not be used. Cf. United States v. Wallace & Tiernan Co., 336 U.S. 793, 796, 69 S.Ct. 824, 93 L.Ed. 1042. If then the evidence was legally obtained, it is immaterial whether such legality is referable to its connection with appellant’s arrest or to the arrest of his co-defendant.
Officer Boone testified:
“Q. How long was it from the time you first entered then until you went in there and put Johney Nun-nally under arrest?
“A. The time it would take to walk from that opening into the barn, to hesitate a moment, and go in there. I would say not more than a minute or a minute and a half.
“Q. And how long did you stay in the barn after you got in there, before you walked back out of the barn?
“A. I came right back out to the front and called Walker down there.”
The appellant was then placed under arrest.9 I do not think that we are required nicely to calculate whether the search preceded the arrest, if the two acts were practically simultaneous and the officers had probable cause for believing that one or more of the arrested persons had committed a felony. See Annotations, 74 A.L.R. 1391; 51 A.L.R. 429; 82 A.L.R. 784.
Certainly the arrest of Johney Nun-nally was lawful whether measured by federal or state standards. As said by Chief Justice Taft in Carroll v. United States, 267 U.S. 132, 156, 45 S.Ct. 280, 286, 69 L.Ed. 543: “The usual rule is that a police officer may arrest without warrant one believed by the officer upon reasonable cause to have been guilty of a felony * * The briefs do not cite us to the authorities as to whether agents of the Alcohol Tax Unit have power to make arrests. United States Marshals, Agents of the Federal Bureau of Investigation and certain other federal officers are authorized to arrest if they have reasonable grounds to believe that the person arrested has committed or is committing a felony. 18 U.S.C.A. §§ 3050 to 3054, inclusive. Under Alabama State law also, an officer may arrest any person without a warrant “when he has reasonable cause to believe that the person arrested has committed a felony.” Alabama Code of 1940, Title 15, § 154. A private person has authority to make arrests “where a felony has been committed, though not in his presence, by the person arrested; or where a felony has been committed, and he has reasonable cause to believe that the person arrested committed it * * Id. Section 158. If federal statutes or regulations do not specifically authorize agents of the Alcohol Tax Unit to make *456arrests, the Alabama statute provides the standard by which the legality of these arrests must be measured. United States v. Di Re, 332 U.S. 581, 591, 68 S.Ct. 222, 92 L.Ed. 210; Johnson v. United States, 333 U.S. 10, 15, note 5, 68 S.Ct. 367, 92 L.Ed. 436; Rent v. United States, 5 Cir., 209 F.2d 893, 897, 900. By any standard, it seems to me that the legality of the arrest of Johney Nunnally cannot be questioned, and there is but slight ground on which to question the legality of appellant’s arrest.
When the officers smelled, saw and heard the things which reasonably indicated to them that an illicit still was being operated in the barn, one of them ran for the front door and the other for the rear door to head off and capture those committing the felony. Their actions showed that their object was to make the arrests. The participants in crime so understood for, as has been stated, one of them escaped, Johney Nun-nally tried to escape (R. 104) but was arrested, and Fred Walker hid in the corn crib.
There are a number of almost “gray horse” cases.10 I respectfully submit *457that the cases relied on by my brothers do not hold or tend to the contrary. Let me briefly - discuss each of them in the order in which it is cited in the opinion. Turner v. Camp, 5 Cir., 123 F.2d 840, is cited merely to the point that every case must be decided upon its own peculiar facts, with which all must agree. In Taylor v. United States, 286 U.S. 1, 52 S.Ct. 466, 467, where a garage adjacent to a city residence was searched, the Court repeatedly pointed out, “No one was within the place, and there was no reason to think otherwise”, and again:
“Prohibition officers may rely on a distinctive odor as a physical fact indicative of possible crime; but its presence alone does not strip the owner of a building of constitutional guarantees * * * against unreasonable search. This record does not make it necessary for us to discuss the rule in respect of searches in connection with an arrest. No offender was in the garage; the action of the agents had no immediate connection with an arrest. The purpose was to secure evidence to support some future arrest.” Taylor v. United States, supra, 286 U.S. at page 6, 52 S.Ct. at page 467.
The Roberson case, 6 Cir., 165 F.2d 752, relates only to the question of whether the barn was a “house” within the protection of the Fourth Amendment, and upon that question we are in substantial agreement. In the Walker case, 5 Cir., 125 F.2d 395, the information on which the search was made was obtained several days theretofore. Likewise, in Johnson v. United States, 333 U.S. 10, 68 S.Ct. 367, 92 L.Ed. 436, a five to four decision, the informer had reported to the officers “that unknown persons were smoking opium in the Europe Hotel. The informer was taken back to the hotel to interview the manager, but he returned at once saying he could smell burning opium in the hallway.” 333 U.S. at page 12, 68 S.Ct. at page 368. The Court commented that, “No suspect was fleeing nor likely to take flight”, 333 U.S. at page 15, 68 S.Ct. at page 369. In Harris v. United States, 331 U.S. 145, 67 S.Ct. 1098, 91 L.Ed. 1399, the search was held reasonable as incident to an arrest. In Trupiano v. United States, 334 U.S. 699, 706, 68 S.Ct. 1229, 1233, 92 L.Ed. 1663, “The agents of the Alcohol Tax Unit knew every detail of the construction and operation of the illegal distillery long before the raid was made.” That case, as has been commented, has been overruled in part. In McDonald v. United States, 335 U.S. 451, 455, 69 S.Ct. 191, 193, 93 L.Ed. 153, the officers heard the adding machine, looked over a transom and saw what was transpiring in the room, all without being discovered. The defendant and his rooming house had been kept under surveillance for two months. The Court specifically commented, “Here, as in Johnson v. United States and Trupiano v. United States, the defendant was not fleeing or seeking to escape.” In United States v. Rabinowitz, 339 U.S. 56, 66, 70 S.Ct. 430, 435, the judgment of the Court of Appeals was reversed, and the Supreme Court held that, “The motion to suppress the evidence was properly denied by the District Court.” In United States v. Jeffers, 342 U.S. 48, 52, 72 S.Ct. 93, 96 L.Ed. 59, the Government admitted that the search of the hotel room was unlawful as to the Misses Jeffries, but contended that it did not invade the respondent’s privacy. The Supreme Court thought that that was “a quibbling distinction”, 342 U.S. 52, 72 S.Ct. 95. Conversely, here, if the search was lawful as to Johney Nunnally, I submit that it was lawful as to the appellant. In Agnello v. United States, 269 U.S. 20, 46 S.Ct. 4, the search was not incidental to an arrest, but was of a man’s dwelling several blocks distant from the place of his arrest, after the offense had been committed and while he was in custody elsewhere. The fore*458going are all of the authorities upon which the majority relies. Not one of them, I submit, sustains the present ruling.
The evidence against the appellant was so unanswerable that he offered no witnesses in his own behalf. It is a serious matter that a man undeniably guilty of felonious crimes should go unwhipped of justice. It is far more serious that we should establish a precedent under which conscientious and vigilant law enforcement officers will be seriously impeded in the performance of their important duties. Rightly understood, the Fourth Amendment requires extra precautions on the part of officers before searching houses, but it is not a bulwark behind which the lawless may seek shelter. Cf. Johnson v. United States, 333 U.S. 10, 13, 14, 68 S.Ct. 367. As said in United States v. Jeffers, 342 U.S. 48, 51, 72 S.Ct. 93, 95, “* * * the Amendment does not place an unduly oppressive weight on law enforcement officers but merely interposes an orderly procedure under the aegis of judicial impartiality that is necessary to attain the beneficient purposes intended.” To construe it otherwise is to make the Amendment itself a force for evil rather than for good, and to plant in it a cancer which ultimately may bring about its destruction. I, therefore, respectfully dissent.
. Mr. Boone testified:
“Q. Now with regard to the source of your information, did they tell you that you would find a distillery out there in Mr. Walker’s barn?
“A. No, it was vague and indefinite, said there might be something on the Clyde Walker place, that’s the way I remember it.” (R. 33)
On questioning by the court, he again testified:
“The Court: * * * Did you have any information that the whiskey or the still was in the barn before you all went out there?
“The Witness: No, sir, our information was that there was a still in the woods around his place, around his house there.
“The Court: From where you parked and the area, the way you were headed out there, the way you were headed, was that the direct route to the woods?
“The Witness: Yes, sir, direct short cut, right straight.” (R. 61)
. Boone testified on the hearing of the motion to suppress:
“Q. Describe that odor to the court, what kind of odor was it?
“A. In my experience of 5 years on this job I refer to it as cooking still mash. It has an acrid odor.
“Q. Mr. Boone, in the course of your work as an ATU investigator have you smelled cooking mash many times?
“A. Yes, sir, I have.
“Q. Does the odor of cooking mash, is it distinctive, as distinct from the smell or odor of fermenting masli?
“A. Generally, it is.
“Q. Is it distinctive as distinguished from the odor of ordinary moonshine whiskey?
“A. Yes, it is.
“Q. Is the odor of cooking mash distinctive in the sense that it occurs only when distilling operations are in prog-gress?
“A. In a general way, that is the only thing that smells like cooking still mash, is cooking still mash.” (R. 39, 40)
On the trial he testified:
“Q, Does cooking mash have a peculiar odor in your opinion?
“A. It has a distinctive odor that is all of its own. It has a mellow, more sour odor than a bakery would put out with yeast, but it is a distinct odor that an experienced investigator would recognize.” (R. 81)
. “After a careful review of the authorities, the court is of the opinion that the motion should be overruled. McBride v. United States, 5 Cir., 284 F. 416; Schulte v. United States, 5 Cir., 11 F.2d 105; Schnorenberg v. United States, 7 Cir., 23 F.2d 38; Carney v. United States, 9 Cir., 163 F.2d 784.
“The search undertaken did not result alone from the odor of fermenting mash. As the officers were crossing the barnyard they observed a strong odor of cooking mash and as they approached the barn they saw a garden hose extending from beneath the barn across the barnyard lot. About the time they reached the barn door they heard a disturbance within as though someone was attempting to flee from the barn. There was a distinct noise from within the barn that sounded like utensils or some other objects being upset. Before reaching the farm, the officers had no information whatever that a still was being operated in the barn. The evidence indicates that the information which the officers obtained pointed to the fact that a still was being operated in the woods on the farm. The officers stated they were on their way to one section of the wooded area in a direct line across the barnyard when they first detected the odor of mash.” (R. 71, 72)
. The necessity for not including a mere trespass on land within the prohibition of the Fourth Amendment was picturesquely stated by Judge Yankwich in Taylor v. Fine, D.C.S.D.Cal., 115 F.Supp. 68, 71:
“If it were possible to submit officers of the United States Immigration Service to harassment every time they search for illegal entrants, if they could be subjected to suits even for nominal damages, the landowners of the Coachella district would be erecting barriers against the United States Government, and, in effect, telling the officers of the Government, ‘Do not enter, no matter what federal *453laws are violated.’ Under the protection of barbed-wire fences, they could thus employ aliens illegally in the country and aid law violations.”

. See cases cited in 79 C.J.S., Searches and Seizures, § 14. As Judge Alger Fee notes in United States v. Vlahos, D.C. Or., 19 F.Supp. 166, 169, there is a marked conflict in the decisions as to buildings outside the curtilage. Of course, if there is no occupant of the premises, the barn would not be protected, Tritico v. United States, 5 Cir., 4 F.2d 664.
. Johnson v. United States, 333 U.S. 10, 14, 68 S.Ct. 367, 369, 92 L.Ed. 436.
. No minute search was necessary because the evidence was obvious. As testified by Mr. Boone:
“Q. When you went in what did you find?
“A. In the barn?
“Q. íes.
“A. A 100 gallon tank type still that had been in operation, except the cover had been rolled off the top; several barrels of mash, a complete distillery, and a pian later identified as Johney Nunnally who I arrested as he was trying to get out the back door. Somebody had already done gotten out.
“Q. Was there anybody else in the barn besides Nunnally?
“A. Not that I could identify. There •was another man there going out the door.
“Q. Did you find anybody else in the barn?
“A. Later we did.
“Q. Who?
“A. This fellow’s brother, Fred Walker.
“Q. Did you put him under arrest?”
. As testified by Mr. Boone:
“A. I signaled bim to come down there, and he came down, and I shook hands with him and introduced myself and told him who I was, and that he was under arrest.
“Q. How long was that after you searched the premises?
“A. If you call that a search, it was within two minutes or less.
“Q. After you went in there and found the property, the still, it was immediately after you walked out, you caught him and put him under arrest?
“A. Yes, sir.”
. In Donahue v. United States, 9 Cir., 56 F.2d 94, 97, it was said:
“The illegal manufacture of liquor is a felony. Act of March 2, 1929 (Jones Act, 45 Stat. 1446, 27 U.S.C.A. §§ 91, 92). If the information which had reached the officers prior to the arrest and search, that is, prior to the opening of the door of the dwelling house, and the knowledge they had gained through their senses of smell and hearing, was sufficient to give them probable cause to believe that a felony was being committed in their presence, they were entitled to enter the dwelling and make the arrest, United States v. Borkowski (D.C.) 268 F. 408; McBride v. United States, 5 Cir., 284 F. 416; Janus v. United States, 9 Cir., 38 F.2d 431, 436; 28 U.S.C.A. § 504, and, as an incident thereof, search the premises, United States v. Borkowski, supra, D.C., 268 F. 408; Vachina v. United States, 9 Cir., 283 F. 35; McBride v. United States, supra, 5 Cir., 284 F. 416. See, also, Garske v. United States, 8 Cir., 1 F.2d 620, and cases there collated. That they had reasonable cause to believe that a felony was being committed in their presence is clear, and they therefore had a right to enter the premises for the purpose of making an arrest, and, as an incident thereto, to seize property found in appellant’s control, which it was unlawful for him to have. Carroll v. United States, 267 U.S. 132, 161, 45 S.Ct. 280, 69 L.Ed. 543, 39 A.L.R. 790; Marron v. United States, 275 U.S. 192, 198, 199, 48 S.Ct. 74, 72 L.Ed. 231; King v. United States, 9 Cir., 1 F.2d 931; Mattus v. United States, 9 Cir., 11 F.2d 503.”
See also Kelley v. United States, 8 Cir., 61 F.2d 843; United States v. Solomon, D.C.Mass., 33 F.2d 193.
In United States v. Kronenberg, 2d Cir., 134 F.2d 483, a Court composed of Judges Learned Hand, Augustus N. Hand, and Frank said per curiam:
“We have never held, and it would be absurd to hold, that the sense of smell was not to be relied upon at all; all we have ever said was that, standing alone, it is not enough. Here it did not stand alone, for all the evidence, taken together, justified the conclusion that, when the officer went down the fire escape, his presence had been observed when the light was put out; and that what Walker carried from the apartment to the incinerator was something the detection of which he wished to avoid. It was, further, a reasonable conclusion from this that this was the opium which smelled so strong.”
McBride v. United States, 5 Cir., 284 F. 416, relied on by the district court, is directly in point. There Judge King, speaking for a court composed of Judges Walker, Bryan and King, said:
“Treating this stable as falling within the description of places covered by the Fourth Amendment, the question in this case is: Can an officer, without warrant, enter upon premises whereon he is informed by his senses a crime is being committed, and, having entered, finding a crime in progress, without warrant arrest the offenders and testify as to what such entry discloses? * * *
“The entry on these premises and into the stable was not to search for evidence, but, upon ascertaining that whisky was in process of manufacture thereon, to arrest those engaged in the commission of an offense then in progress. If an entry can be made without warrant in cases where the officers acquire information evidencing the present commission of a *457crime, then the use of knowledge acquired by such entry is not the use of knowledge illegally acquired.” 284 F. at pages 418, 419.
