“These arrangements,” says the Commission, “took the form of special rates, rebates and drawbacks, underbilling, reduced classification, or whatever might be best adapted to keep the transaction from the public; but the public very well understood that private arrangements were to be had if the proper motives were presented. The memorandum book carried in the pocket of the general freight agent often contained the only record of the rates made to the different patrons of the road, and it was in his power to place a man or a community under an immense obligation by conceding a special rate on one day, and to nullify the effect of it on the next by doing even better by a competitor. “Special favors or rebates to large dealers were not always given because of any profit which was anticipated from the business obtained by allowing them; there were other reasons to influence their allowance. It was early perceived that shares in railroad corporations were an enticing subject for speculation, and that the ease with which the hopes and expectations of buyers and holders could be operated upon pointed out a possible road to speedy wealth for those who should have the management of the roads. For speculative purposes an increase in the volume of business might be as useful as an increase in net returns; for it might easily be made to look to those who knew nothing of its cause like the beginning of great and increasing prosperity to the road. But a temporary increase was sometimes worked up for still other reasons, such as to render plausible some demand for an extension of line or for some other great expenditure, or to assist in making terms in a consolidation, or to strengthen the demand for a larger share in a pool. “Whatever was the motive, the allowance of the special rate or rebate was essentially unjust and corrupting; it wronged the smaller dealer oftentimes to an extent that was ruinous, and it was generally accompanied by an allowance of free personal transportation to the larger dealer, which had the effect to emphasize its evils. There was not the least doubt that had the case been properly brought to a judicial test these transactions would in many cases have been held to be illegal at the common law; but the proof was in general difficult, the remedy doubtful or obscure, and the very resort to a remedy against the party which fixed the rates of transportation at pleasure might prove more injurious than the rebate itself. Parties affected by it, therefore, instead of seeking redress in the courts, were more likely to direct their efforts to the securing of similar favors on their own behalf. They acquiesced in the supposition that there must or would be a privileged class in respect to rates, and they endeavored to secure for themselves a place in it.
