uld well be imagined,entered for a trial that was to determine,not only superiority for that occasion,but was to settle for the future the gen-eral design of the locomotive boiler.The results of the trials show the Rocketto be the only engine to make the 70miles constituting the runs. The Rock-ets average evaporation was 5.34 poundsof water per pound of coke, against anaverage evaporation of 2.2 lbs. of water pursuing an ignis faluiis, as will beshown by the evaporation data for theseengines, which had 306 and 283.8 squarefeet of flue heating surface, respectively,as against the 117.8 square feet of theRocket, and an evaporation of 6.64 lbs.per pound of coke for the Phoenix, with9.61 lbs. for the Arrow. In the competi-tive trials, while the evaporation of theRocket was far above the other boilers,the results as then obtained were im-proved upon afterward by decreasing thediameter of exhaust tip for the purposeof stimulating the draft. The light thusgained on drafting was no doubt made

Amticaii Madtinitt NEW YORK CENTR.\I, BOILKR, I.Wl. Fig. C on Table. The second engine, the Sanspareil,built by Timothy Hackworth, had a cyl-indrical boiler 6 feet long and 50 inchesin diameter, with a single tube 24 inchesin diameter at the grate and 15 inches atstack, having a return bend. The fireboxheating surface was 15.7 sq. ft., and gratearea was 10 sq. ft., while the tube heatingsurface was 74,6 sq. ft. The third enginein the contest was the Novelty, built byBraithwaite and Ericsson. The boiler ofthis engine was a wonderfully complexafTair, having a vertical firebox sur-rounded by water, and one tube 4 inchesin diameter, immersed in a horizontalsection of the boiler, through which itpassed three times by return bends be-fore entering the stack, the flue being made by the Sanspareil. There is norecord of the boiler performance of theNovelty, that engine having sufferedfrom a number of break-downs. Enoughdata was, however, deduced to firmly en-trench the niulti-tubular type of b
