If the splice is to be permanent a better junction may be made as follows: Prepare the wires as before, bend up slightly the two ends, lay them side by side, and bind them tightly together with a whipping of fine wire; then turn the ends back on the splice and solder the whole together. Another good joint may be made as follows: Prepare the wires, but allow a greater length; lay them together and twist each about the other at right angles and in opposite directions; then solder all together. In all cases trim the splices so that there shall be no projecting wires to cut through the insulation. =Continuity.=—It is possible that a wire may be cut or broken at some point where such cut or break cannot be seen. If there be any reason to suspect such a break, the continuity of that wire may be readily tested by connecting it to the testing-magneto, using leading-wires known to be good, and proceeding as in other testing. CHAPTER IV. GUN-COTTON.—HOW PACKED.—STOWAGE.—CARE.—INSPECTION AND DRYING. PACKING AND STOWAGE OF WET GUN-COTTON. Each Service Torpedo, completely filled with wet gun-cotton, is packed in a rough box for transportation and stowage. The Exercise Torpedoes, ten filled with wet gun-cotton and two empty, are packed six in a box. Each filled torpedo has attached to its case a tag on which is marked the gross weight of the torpedo in pounds and ounces, the initials of the Superintendent of the Gun-cotton Factory and the factory number of the charge from which the contained gun-cotton is taken. When received on board ship the cover on which the address is marked is to be reversed. The torpedoes are then stowed in the magazine in a manner similar to that now employed in stowing shells.

The glass jars for dry primers, filled with dry gun-cotton, are put in wooden cases, painted white, fitted with sliding covers as described on p. 13. The cases are marked “DRY GUN-COTTON PRIMERS. NOT TO GO BELOW.” They are packed in a rough box for transportation. When received on board ship the cases containing the jars are placed in different parts of the ship, but are never to be stowed below the water-line.
