This engineweighed 3J tons. They subsequently built several grasshopper engines(Fig. 59), some of which ran many years, doing good work,and one or two of which are still in existence. The first— 210 THE MODERN STEAM-ENGIKB. the Atlantic —was set at work in September, 1832, andhauled 50 tons from Baltimore 40 miles, over gradients hav-ing a maximum rise of 37 feet to the mile, and on curveshaving a minimum radius of 400 feet, at the rate of 12ito15 miles an hour. This engine weighed 6| tons, carried 50pounds of steam—a pressure then common on both continents. 59.—The Atlantic, 1882. —and burned a ton of anthracite coal on the round blast was secured by a fan, and the valve-gear wasworked by cams instead of eccentrics. This engine madethe round trip at a cost of $16, doing the work of 42 horses,which had cost $33 per trip. The engine cost $4,500, andwas designed by Phineas Davis, assisted by Ross Winans. Mr. Miller, on his return from the Liverpool & Man-chester trial, ordered a locomotive for the Charleston &Hamburg Railroad from the West Point Poundery. This STEAM-LOCOMOTION ON RAILROADS. 211 engine was guaranteed by Mr. Miller to draw three timesits weight at the rate of 10 miles an hour. It was builtduring the summer of 1830, from the plans of Mr. Miller,and reached Charleston in October. The trials were madein Hoyember and December. This engine (Fig. 60) had a vertical tubular boiler, inwhich the gases rose through a very high fire-box, intowhich large numbers of rods projected fro
