THE CALORIC SHIP. To the Editor of the Times. Sin—Your New Fork correspondent, under date of tbe Ist of February, has made some statements in rtgard to tbe caloric ship which demand correction. That “ caloric, as a motive power, is not now even in this country” is quite true ; it has generated steam for tho propulsion of our steamers upwards of 40 years, lint caloric has not before been applied to atmospheric air for producing motive power and pro pelling ahipson the plan adopted by me. Air engines have, it is true, been planned and made in nearly all civilised countries during the last half century. The caloric engine, however, originated with me—its form as well as its name. Your correspondent questions whether in an engine, “ constructed as this engine is, its power could be continued for any considerable length of time.” Experience, during a recent trip to Washington, has proved that one of the most remarkable features of this engine is its perfect uniformity of action. As to the mechanical combination and design of the engine of the caloric ship, tbe combined engineeringftalent of this country differ from your correspondent. Your correspondent next deems it to be “ demonstrated” that because the caloric ship performs only seven miles an hour on six tons of coal in 24 hours, “ there is not as much motive power gained by the same quantity of coal on the caloric system as there is by steam.” Does he know of any steamship of the size of the Ericsson, viz., 260 feet long, 40 feet beam, and 18 feet draught of water, capable of running at a rate of seven miles an hour on six tons of coal in 24 hours? The comparison founded on (lie supposed greater effect of a tug-boat is worthless. Engineers well know that a steam ship may be towed on less fuel than would suffice merely to move her machinery. There is however, one way of renderin'l- - a complete test of the comparative efficiency <Tf the engines of the caloric ship and a steamship of her class, and the writer feels no hesitation in subjecting the caloric ship to that test. She is ready to take the Arabia or the Baltic in tow and effect a higher rate of speed than either of these ships running by themselves on a given quantity of fuel. Tho weight of tbe moving parts of the machinery of the caloric ship being fully equal to that of the steamers, such a proof would be conclusive as to the economy of the motive power of the two systems. The assertion of your correspondent that, at the rate of seven miles an hour, the caloric ship could not carry coals enough to reach England, has no foundation whatever. The Ericsson can carry upwards of GSO tons in her bunkers and bolds, fore and aft. This, at six tons in twenty-four hours, would suffice for 108 days. At a rate of seven miles an hour, that would give a distance of more than 18,000 miles—equal to crossing the Atlantic six times 1 But we are told that no room would he left for freight. This assertion is equally unfounded, since the Ericsson, independently of bunkers and holds, fore and a ft, exhibits a dear freight deck 240 feet long, which, deducting the space occupied by the engine trunk, contains upwards of 800 tons measurement. Thus, according to your correspondent’s own statement of consumption of coals and rate of speed, the caloric ship can readily perform even an Australian voyage and cairy 800 tons ol freight, with coals enough left for a return trip to the Cape of Good Hope. Tbe clear berth deck of the caloric ship, with her uninterrupted passages and state rooms extending round tbe entire ship, have been passed over by your correspondent. I amj Sir, very respectfully, your most obedient wrrant. J. Eiucsson, New York, March 19,1953. .
