The Congressional Joint Commission to Investigate the Postal Service, which reported on January 14, 1901, is authority for the fact that, at that time, railway mail pay was not excessive. Senator William B. Allison, of Iowa; Senator Edward S. Wolcott, of Colorado; Senator Thomas S. Martin, of Virginia; Representative Eugene F. Loud, of California; Representative W. H. Moody, of Massachusetts, and Representative T. C. Catchings, of Mississippi, six of the eight members of the Commission, then united in the following: "Upon a careful consideration of all the evidence and the statements and arguments submitted, and in view of all the services rendered by the railways, we are of the opinion that 'the prices now paid to the railroad companies for the transportation of the mails' are not excessive, and recommend that no reduction thereof be made at this time." Fifty-second Congress, Second Session, Senate Document No. 89, pp. 19, 22, 25, 29. Since the Commission reported, the volume of the American mails, the revenue of the American postal service and its demands upon the railways for services and facilities have greatly increased. The costs of supplying railway transportation have also greatly increased. The necessary cost of railway property per unit of service has increased, and in consequence the amount required as a reasonable return thereon, on account of higher wages and prices, the higher standards of service demanded and the higher value of the real estate required for extended and necessary terminal plants. Operating expenses have grown by reason of repeated advances in rates of wages paid to employees of every grade and increased prices of materials and supplies. Taxes have increased with the rapidly augmenting exactions of State and local governments and the imposition of an entirely new Federal corporation tax.[G] Yet during this period of rapidly advancing railway expenses, and in spite of the fact that at its commencement the railway mail pay was not excessive, the rates of payment for railway mail services have been subjected to repeated and drastic decreases accomplished both by legislative action and by administrative orders. These reductions have so much more than offset the rather doubtful advantages which the railways might be assumed to have obtained from the increased volume of mail traffic that in 1912 they find their mail service more unprofitable than ever before.
