Remington, Winchester and the rest will retire in favor of new contrivers, devoted, like them, to the simple task of facilitating the flight of the leaden arrow with its grooved feather in steel or iron. With them will rise and fall a parallel series of names on a broader and more sonorous field the field of heavy artillery, the ponderous Wiard being full brother to the liliputian Sharpe.
An inventor at the Fair, by the name of Wiard, was exhibiting an iceboat he had invented to run on the upper Mississippi from Prairie du Chien to St. Paul during the winter months, explaining how useful it would be thus to make a highway of the river while it was closed to ordinary navigation by ice.
In fact, placing the inner part of the gun in initial tension and the outer part in compression would better resist the effect of internal heat. But Mr. Wiard believes that the longitudinal expansion of the inner stratum of the gun is the principal source of strain.
Wiard, of New York, makes an ingenious argument to show that large cannon burst from the expansion of the inner part of the gun by the heat of frequent successive explosions. In this he is sustained to some extent by Mr. Mallet, of Dublin. The greater the enlargement of the inner layer of metal, the less valuable is the above principle of initial tension.
