All the foregoing data were reported to the Postmaster-General in response to his request but he made no use of these items, an omission manifestly to the serious disadvantage of the railways and having the effect of unduly reducing his estimates of the cost of the mail service. Similarly, the Postmaster-General omitted to use the data he had obtained from the railways showing the volume of free passenger transportation, already referred to, supplied to the officers and agents of the Post Office Department and his estimates contain no recognition of the cost of this service although its extent should be a matter of record in the Department as it is furnished only on its requisition. The space in passenger coaches occupied by these representatives of the Post Office Department, traveling free, was not assigned to the mail service but was treated as passenger space. VII. THE MONTH OF NOVEMBER IS NOT A FAIR AVERAGE MONTH IN ANY RAILWAY YEAR OR ONE THAT IS TYPICAL OF A YEAR'S BUSINESS AND ITS USE AS THE SOLE BASIS OF THE POSTMASTER-GENERAL'S CALCULATIONS WAS SO UNFAVORABLE TO THE RAILWAYS AS TO DEPRIVE THE RESULTS OF ANY VALUE EVEN IF IN ALL OTHER RESPECTS HIS METHODS WERE BEYOND CRITICISM. All the Postmaster-General's calculations, reported in Document No. 105, and by him relied upon therein, and elsewhere, to substantiate his attack upon existing railway mail pay, depend solely upon data for the single month of November, in the year 1909. It is obvious, therefore, that the validity of his conclusions, if all the rest of his processes were accurate and his deductions otherwise sound, would depend upon whether November is sufficiently typical of the railway year to be safely used as the sole basis for conclusions applicable to a whole year. The truth is, however, that November is not a typical or average month and that all of its deviations from the averages of the year are such as greatly to favor the result which the Postmaster-General was seeking. It may well be doubted whether the railway year contains any month that can properly be regarded as typical of the whole period but if it does, the month of November, with four Sundays, two holidays and only twenty-four working days, is certainly not such a month. The Interstate Commerce Commission publishes the monthly aggregates of railway receipts and these official data conclusively prove that November, 1909, was the one month for which the data were most strongly favorable to finding, by the Postmaster-General's method, an abnormally low apparent cost for the passenger train services and, consequently, for the mail service.
