The perform- ance is said tu be equal but it probablyis not as far as coal burned goes, becauseE has burned more coal than A for thetrip. But A and B are equal in per-formance by the ton-mile-per-hour. Ahas made 14,400 ton-miles-per-hour andhas burned x tons of coal. B has made is hardly any one who would maintainthat the performance of each was both passed through the same spaceand were both acted upon by the sameforce of gravity, supposing both to beequal in size and weight. On nine rail-ways out of ten both would be considered. ■WE HAD COAL TO DURX AXD TO BLOW AWAY ALL THE TKir.(Copyright by the Buffalo Express.) 16,200 ton-miles-per-hour and has burnedX + y tons of coal. For sake of ex-ample, suppose 14,200 divided by x equals16,200 divided by x + y tons of , A equals B in the matter ofperformance when the ton-mile-per-houris used, as it should be. If two men go up a couple of thou-sand feet in a balloon, and one jumpedout at that height and the other camedown with the aid of a parachute, there equal in performance and so stated on themonthly sheet, though one came down inseconds while the other occupied minutesto make the same journey. If one engine burns more coal than an-other there is some reason for it. Ifboth engines are in the same condition,with dampers, draft appliances, steamingqualities, men fairly equal, the differencefor equal trains and conditions will veryprobably be d
