In addition to the boats being built by firmsmaking that a specialty, naval constructors are giving particular attention to a ship of aver-age dimensions to meet the requirements of torpedo warfare. The development has alreadycarried us from second-class torpedo-boats, up through boats of the first class.

For all naval warfare there is needed a torpedo possessing high speed, good range, as- TORPEDOES. 865 sured directive power, simplicity, and liandiness ; it must have inherent and positive directiveforce to resist any ettorts to cause deviation. In order to be launchetl without deflection from.
