When they wanted to turn some new screw in freight rates against Rice, the railroad officials would whip themselves around the stump by printing a new tariff sheet on a type-writer, and tacking it, perhaps, as one of the Interstate Commerce Commission said, on some back door in their offices. This they called "publishing" their rates, as required by the Interstate Commerce law. To Rice, asking for tank-car rates, they would send this printed sheet, showing that if he shipped by tank-car he must pay for every pound, and they held him off with this printed, official, and apparently authentic tariff, though shipping 44,000 for 20,000 pounds for the trust. This was done after the Interstate Commerce Act went into force.[425] One of these roads assured Rice that its rates had been fixed "by the special authority of the National Railway Commissioners." The fact was, as the Commission declares: "The Commission never investigated coal-oil rates, or gave special authority for their renewal; it never sanctioned any difference in the rates as between tank-car and barrel shipments, and had never, up to the date of this letter, had its attention called to them in any way."[426] The representative of the combination was called as a witness before the Interstate Commerce Commission. "We pay for exactly what is put in the tanks,"[427] he testified. "In fact, this was never done," says the Commission.[428] Even the railroad officials, who could go any length in "blind-billing" for him, could not "go it blind" on the witness-stand to the extent of supporting such a statement. "Our price per tank-car was not based on any capacity or weight; they have been made simply per tank-car."[429] "What, generally, is the object of false billing?" "I suppose to beat the railroad company."[430]
