There is generally too much attentionbestowed on resisting transverse strain, ami nearly all gunshave been constructed on theoretical principles which do nottake account of the .suddenness of the shock, nor of transverseor of tlexional strains. The new pieces have been constructed on absolutely differ-ent principles. A carefully ;l form, after ijraclicaltests, offers all guarantees for a gun fired under reasonableconditions. The tendency is to increase the length Director of Artillery, Colonel Hoipie, has taken a greatste|i in Ibis Important (luestion. He has ordered Canet gunsof 55 calibers ; and, at last, at liuelle a 15 cm. ( in.) gun of 90 calibers length has been tried wilh success. There is everyreason to think that the guns of the fuliiie will be of greatlength. With regard to service on board ship, great length has beenthought to constitute a great dillicully.
