Rice took to the water whenever he could, as hunted animals do. The Ohio, Mississippi, Tennessee, Missouri were public highways that had not been made private property, with general agents or presidents to say "No" when asked permission to travel over them. He began to ship by river. The chairman of the Committee of Commerce rose in his seat in Congress to present favorably a bill to make it illegal to ship oil of less than 150 degrees fire-test on the passenger boats of inland waters. The reason ostentatiously given was public safety. But, as was at once pointed out in the press, the public safety required no such law. The test proposed was far above the requirement of safety. No State in its inspection laws stipulated for so high a test. Most of the States were satisfied with oil of 110 degrees fire-test; a few, like Ohio, went as high as 120 degrees. All but a very small proportion of the oil sent to Europe was only 110 degrees fire-test. The steamboat men did not want the law, and were all against it. There was no demand from the travelling public for such legislation. General Warner, member of Congress, said, in opposing the bill: "Petroleum which will stand a fire-test of 110 degrees is safer than baled cotton or baled hay, and as safe as whiskey or turpentine to be carried on steamers. What is the object, then? There can be but one, and I may as well assert it here, although I make no imputation whatever upon the Committee of Commerce, or any member of it. It will put the whole carrying trade of refined petroleum into the hands of the railroads and under the control of ... a monopoly which has the whole carrying trade in the oil business on railroads, and they will make it as impossible for refiners to exist along the lakes and the Ohio River as it is impossible for them now to exist on any of the railroads of the country." Why the trust, though it was the greatest shipper, should seek to close up channels of cheapness like the waterways was plain enough. They were highways where privilege was impossible. With its competitors shut off the railroads by privilege, and off the rivers by law, it would be competition proof. The United States authorities, too, moved against Rice, responsive to the same "pull" that made jumping-jacks for monopoly out of committees of commerce and railway kings. When the Mississippi River steamer _U.P. Schenck_ arrived at Vicksburg with 56 barrels of independent oil, the United States marshal came on board to serve a process summoning the officers and owners to answer to the charge of an alleged violation of law. Several steamboats were similarly "libelled."
