16 MARINE REVIEW. The Test of the Detroit. Wm. T. Malster, President and General Manager The Columbian Iron Works and Dry Dock Co., of Baltimore City. : Office and works, Locust Point. \ Me BALTIMORE, Md., May, Ist. 1893. ~ Vacuum Oil Co., Rochester, N. Y. a Gentlemen: It gives me pleasure to reply to your letter and state that we used the Vacuum Marine Engine Oil and 600 W. Mineral Cylinder Oil on the preliminary and official trials of the U.S. S. Detroit with the most satisfactory results. A The Detroit is a 2,000 ton cruiser equipped with two triple expansion en- gines of 6,000 indicated horse power, H. P. Cylinder 26%", Ie Pi 30), We, P. 63 and stroke 26"; revolutions per minute, 180; steam pressure above atmosphere ; at H. P. Cylinder, 165 Ibs.; piston speed 780 feet per m., developing a speed of ship of 19.27 knots per hour. : The oil service was at all times during the preliminary and official trials sufficient on engines and cylinders and at no time was there any necessity for supplementing this by hand oiling. Examination of cylinders and the various crank-pins and important journals since the trial has show them to be in perfect condition. Personally I would umhesitatingly use your oil on any ship in which I was interested, whatever might be the speed or the pressure per square inch on the journals, as I am confident it is equal, in all respects, to the best quality of olive or sperm oils. Yours very truly, THE COLUMBIAN IRON WORKS & DRY DOCK CO., Wu. T. Malster, President.
