delivered the opinion of the Court.
The appellee-sued the appellant in the Superior Court of Baltimore City, and the case was removed to Baltimore County for trial. The declaration sets up a claim for park tax from February 1st, 1885, to March 15th, 1881.
The appellant was incorporated under the G-eneral Railway Law of the State, and was, by ordinance No. 150 of the ordinances of the City of Baltimore of 1880, (Rev. City Code of 1885, page 323,) authorized to construct certain street passenger railways in the streets of the city, subject to certain conditions, as follows, to wit: “to pay to the City Register for the use of the parit fund, quarterly, twelve per centum of the gross receipts accruing from passenger travel within the city limits; and for each car in daily use upon said railways a license tax of five dollars shall be paid yearly to the City Comptroller. ”
By the Act of 1882, chapter 229, the Legislature assumed control of the whole matter, fixed the fare at five cents for aclults, and three cents for children, and reduced the park tax from twelve to nine per centum of the gross receipts. ■
The appellant had three railway lines, viz: The Huntingdon avenue line, Columbia avenue line, and the Pratt Street line. The two last named were wholly within the city limits; but the first extended beyond the city limits for the distance of one-half mile; and this fact has given rise to this controversy. For this half mile of track, beyond the city limits, of the Huntingdon *413avenue line, the company deducted one-half the gross receipts of the company from all their lines, and paid the city only the nine per cent, tax on the other half of the receipts. To this claim on the part of the appellant of the right to deduct one-lialf of the whole receipts of the company from all their lines, because of this half mile of trade of one of the lines which is outside the city limits, and to pay no more park tax than what the other half yields, the appellee objected, and brought this suit to recover such sum in addition as the law entitles the city to receive.
The Huntingdon avenue line travels 2.69 miles, one-half mile thereof only being outside the city. The distance travelled by a car of the Columbia avenue line is 3.58 miles, wholly within the city, and the Pratt street line, wholly in the city, travels 2.36 miles. The aggregate of car mileage is 8.63 miles; but, as certain portions of the tracks are common to each, making allowance for the distance travelled on common tracks, the total of track mileage is only 7.08 miles.
Inasmuch as one of these lines extends beyond the city, and into Baltimore County, the gross receipts from or on account of that portion of the track which is without the city limits ought not to pay any part of the nine per centum tax which has been imposed for the privilege accorded by the city to the appellant of using its streets for railway purposes. But it is self-evident that an arbitrary deduction of one-half the gross receipts of all the lines of the appellant to represent the revenues derived from the one-half mile of track outside the city cannot be right. To deduct one-half of the gross earnings before computing the tax to be paid, as representing the revenues derived from that half mile outside the city limits, which is only about one-sixteenth of the whole mileage of the appellant, is suggestive of such an enormous amount of work done and money earned by that *414portion of the road, as compared with the rest of the mileage within the city, as taxes credulity too heavily for acceptance as a fair basis of settlement with the city. Having accepted their privileges on the condition of paying this tax upon the gross receipts, it was the duty of the appellant to furnish an accurate statement of such receipts. Upon a bill for discovery in aid of this suit, the total gross receipts have been given in response to the demand as $277,269; hut that amount includes the receipts from the county part of the tracks, of which they say they hare kept no account separate and apart from the other parts of their lines. In their answer to the bill for discovery, and by the testimony of their officers, it is shown, that they thought it impracticable by the methods- and agencies used by the company, to keep a separate account of the fares received from that part of the road.
Having no separate fare for the part of the road lying outside the city limits, but the five cents paid outside the city entitling the passenger to ride to any part of the city on that line, and by a free transfer to any part of the city traversed by any one of the lines of the appellant, and vice versa for persons getting on in the city and going to the county, it is clear that some method must he adopted to determine with reasonable accuracy what proportion of the revenues shall be deducted as not liable to tax. The evidence shows that a very small part of the fares received were paid for'rides 'begun and ended on the county part of the track. The five cents paid, therefore, in very much the larger number of instances, represented rides wholly in the city, and those begun in the county and ended in the city, or in the city and ended in the county; and inasmuch as portions of the tracks in the city were travelled by each line of cars; and inasmuch as the system of transfers from one line to another prevailed, by which passengers could start on *415one line and end their trip on another, it is plain -that any method which migdit he adopted to ascertain a proper deduction from the total gross receipts to represent the earnings of that part of the Huntingdon avenue line which was outside the city limits, must involve a calculation on the basis of the gross receipts from all the lines.
The first five exceptions relate to evidence offered on hehalf of the appellant which was rejected. By that evidence it was sought to establish a proper basis of computation, on the ground that the larger part of the passengers on that line got on in the county and rode into the city, or in the city and rode into the county, than began and ended their rides in the city. Witnesses who rode on that line twice or more a day stated their estimates from casual observation as to the proportion of passengers so doing. That the exclusion of such evidence was no ground of error is apparent from several considerations. If it was impracticable, as the company stated, to keep an accurate account by a record of the passengers riding on the road, when, and where they entered, and where they alighted, it is perfectly clear, that the testimony of passengers who only observed now and then, and who did not tell and could not tell at what point outside the city the passengers they observed got on, or where they got off in the city, or vice versa, could not supply a safe method of ascertaining what was wanted. It would not only he the merest guess, resulting from only occasional observation, but it gave no possible help toward determining what proportion of the journeys of these passengers was made on the tracks in the city, and the track outside the city. Certainly, unless some method of reaching that proportion was supplied by proof 'in addition to the statements of those witnesses, their statements would not enable a jury to form a reasonably lair basis for tlie jury to determine what was the real earnings of Baltimore County track.
*416The sixth exception brings for review the action of the Court on the prayers submitted by the respective parties; and as the second prayer on the part of the plaintiff was adopted by the Court below, as supplying to the jury the true method of making the ascertainment of proper allowance for the receipts on account of the track outside of the city limits, we will consider that first. The evidence having supplied the means of determining with certainty how many miles each car of the company, on each line, travelled during the period involved in the suit, by proof of how many round trijDS each car on each line made during the period sued for; and that proof enabling the j ury to find with accuracy how many miles were travelled by the cars of the company upon the half mile of track of the Huntingdon avenue line outside the city; and being given the total gross receipts of all the lines, the Court gave the jury an instruction for an arithmetical proportion, by which the half mile track’s part of the gross receipts for fares were ascertainable. This instruction, in the absence of a better one, supplied by actual account of each fare paid in the county for a ride begun there and ended there, or begun there and ended in the city, and giving the distance traversed in the county and in the city, and vice 'versa, seems to us to reach the justice of this case, and to be free from objection. The rule, thus set up, is as follows: “The greatest sum to which the defendant is entitled, as a deduction from its total gross receipts from passenger travel during the period from February 1st, 1885, to March 15th, 1887, (the period embraced in this suit,) in respect of its passenger travel outside the city limits, is that sum which bears the same proportion to said total gross receipts, as the number of miles travelled by said cars outside the city limits bears to the total mileage travelled by said cars; and if the juiy shall'find that the total, mileage travelled by the cars *417of the defendant on its said three lines from February 1st, 1885, to March 15th,. 1887, was 1,954,156 miles, and that during the same period that portion of said total mileage of 1,954,156 miles which was travelled hy the defendant’s cars on that portion of their line which was outside the city limits was 126,781 miles, and that the total gross receipts of the said company, from passenger travel on all its said lines during said period was $277,269, then the siun to be deducted from said total gross receipts in respect of its passenger travel outside of the city limits is to be ascertained as follows, that is to say: as 1,954,156 : 126,781:: $277,269 : $17,985; which said sum of $17,985 is to he deducted from said sum of $277,269, and upon the remainder, to wit, the sum of $259,284, the plaintiff is to recover nine per cent., less such amount as the defendant has already paid to the plaintiff on account thereof for the period from February 1, 1885, to March 15, 1887, as shown by the witness Fender.”
It appears clear that the Court thought, that as there was no evidence enabling it or the jury to find how far each passenger who rode on the cars travelled, the only way to approximate a fair basis of settlement was to act on the assumption that each part of each line carries as many as any other part. This seems reasonable, and is the principle the Legislature has sanctioned as the mode of ascertaining the taxable gross receipts of steam rail roads whose tracks are partly within, partly without the State of Maryland. Section 153, of Art. 81, found in vol. 2, Code of Public General Laws, page 1264, makes this provision: £‘Whenever the road of any railroad company, organized under the laws of this State, shall extend beyond the limits of this State into any other State or States, and the return of the financial officer of said company, made to the Comptroller, shall not show certainly and accurately the precise amount of gross receipts *418within this State, the Comptroller may ascertain said amount by making the gross receipts in this State bear the same proportion to the whole gross receipts of said company, as the number of miles of said road in this State does to the whole number of miles in length of said road. ”
In State vs. Phil., Wilm. & Balto. R. R. Co., 45 Md., 384, this Court said that “this rule is fair and reasonable.” The Court said, “it was true that the receipts on one part of the road might be greater than on another, but perfect equality in the assessment and apportionment of taxes is unattainable,”' and hence they adopted this rule as right. This Court cites The Delaware Railroad Tax Gase, 18 Wall., 208-231, where this rule was approved by the Supreme Court of the II. S. It was also approved in State Railroad Tax Cases, 92 U. S., 608-611, and Western Union Telegraph Co. vs. Massachusetts, 125 U. S., 530-552.
There is one difference in the principle adopted in this case and that prescribed in the statute quoted, and approved in the cases decided, which ought to be noted, and which has already been alluded to. It is that this instruction adopts the basis of the full mileage traversed by the cars of the appellant instead of the simple track mileage. The reason for this, and the justice of it, grows out of the fact that there is a portion of the track common to some of the lines, and as the cars pass over the tracks they are to be presumed to be earning fares by the carriage of passengers; therefore the actual round trips made by each car represent its full earnings, and the exact distance also it has traversed, and therefore gives a more accurate method of reaching the earnings of that part of the road which is not subject to tax. Approving, as we do, the granting of the plaintiff’s second prayer, it follows', as a consequence, that the defendant’s first prayer was properly rejected. If any injustice is done the appel*419lant, it results from its neglect to furnish, a more accurate method of fixing the half mile track earnings. The plaintiff’s first prayer, and the second, third and fourth prayers of the defendant, involve the construction of the ninth section of ordinance No. 150, which imposes the tax, and the admissibility of certain evidence of the appellant which by the first prayer of the appellee is asked to be stricken out, and which was, by the Court below stricken out.
Section 9 of the ordinance No. 150 of 1880 (which granted appellant its privileges and imposed the tax sued for,) provides “that whenever the amount of the gross receipts of any passenger railway company, owning or operating any railway tracks in the City of Baltimore, now required to be paid to the city register for the use of the park fund, shall be reduced from 12 per cenlum to any less amount, the said reduction shall apply to the railways hereby authorized to be constructed.”
The appellant offered evidence touching certain settlements of the city with some other railways with which the city was in controversy, in which the city submitted to certain deductions for the purpose of securing a settlement. The appellant claimed the benefit of like deductions, on the contention that it was a reduction of the per centum of tax under the ninth section of the ordinance above quoted.
It is unnecessary to elongate this opinion by the recital of what was done by the city in compromise of litigation with other companies, for it is very clear to us, that such acts on the part of the city were not what the ninth section of ordinance No. 150 was providing for, and guaranteeing to this appellant. The acceptance 'by the city of less than was due, for the purpose of ending suits and controversies on amounts claimed as due, by way of compromise, was certainly not a reduction of the per centum of tax; and was not what was *420intended by that clause of the ordinance. It only meant, that if thereafter any other company should be granted privileges such as were accorded the plaintiff, and a less per centum of .tax on the gross receipts of such company should be required of them, than was required'of appellant, or if the rate of per centum should be diminished from the tax on companies chartered before the appellant, then such diminution of rate should also enure to the benefit, of the appellant. The city authorities might possibly have exceeded their authority, and made illegal settlements, but it is not necessary for us to consider whether they did or not; the appellant is very clea.rly not entitled to abatement because of those arrangements by way of compromise. Without relying on this view wholly, the appellee contends that since the passage of the Act of 1882, chapter 229, fixing the park tax at nine per centum, ordinance No. 150 of 1880 has become a nullity, because the city has no power to-modify, reduce or repeal the park tax. There is much force in this argument; but we are so clear in the view we have already expressed, this contention of the appellee need not be considered. A proper construction of' the ordinance excludes the view urged upon us by the appellant’s counsel.
(Decided 17th December, 1889.)Finding no error, the judgment must be affirmed
