would afford ample accommodation for officers and crew, embracing, also, stowage for provisions and means of cooking. Ventilation and light would be obtained by hatchways, fitted with skylights; and there would also be side scuttles, which, from their height above water, would admit of their being generally open. The rig would be that of a three-masted schooner, having fore, main, and mizen gaffsails, with a fore staysail and two jibs, inner and outer. When going into action, the sails would be lowered and stowed; the vessel would then be entirely under steam. To each mast there would be a yard of suitable dimensions, for the double purpose of towing the torpedoes and setting flying square sails. The rigging would not be rattled; the ascent to the masthead would be by a Jacob’s ladder before the mast; there would be a small top to each masthead, principally for the use of the look-out men. The crew would be stationed upon the orlop deck, each man being provided with a life-belt. With regard to boats, there may be a small stern boat, and two larger boats, stowed on deck; and upon going into action, gripes or lashings should be cast off so that the boats would instantly be disengaged from the vessel. Torpedo vessels for foreign service should, under the present difficulties of keeping iron from oxidizing and fouling, be built of timber. For home service, vessels constructed of iron would be preferable, and with very reduced masts, to enable them to pass under the yards of a vessel. One or two light guns, to bring-to an unarmed vessel, and for signal purposes, on the weather-deck, and fired over all. [Illustration: Plate 3. Kell Bros. Lith. London.
