These wires are 97 HANDBOOK OF EXPLOSIVES joined together in the cap by a very fine and delicate wire, whichrough handling may break and make the electric fuze charge which they contain is just as sensitive to shock, and justas easily affected by moisture, as that of the blasting cap; so the same.

ELECTRIC FUZE rules for storing and handling must be observed. Electric fuzes areput up 25 or 50 in pasteboard cartons, which are packed for shipmentin wooden cases. They are made in four grades, numbered 4, 6, 7and 8, and with wires from 4 feet to 30 feet long. The strength ofelectric fuzes is exactly the same as that of blasting caps bearing thesame number, and nothing weaker than the No. 6 grade can be de-pended on for best results from high explosives. TO PRIME A CARTRIDGE WITH AN ELECTRIC FUZE The correct way to prime a high explosive cartridge with anelectric fuze is to follow the same methods as when fuse and blast-ing cap are used. (See pages 88 and 90.) The common custom of taking one or more loops, or half-hitches, around the cartridge with the wires themselves, after insertingthe electric fuze cap in a hole made diagonally in the side of thecartridge near one end, is always to be condemned. The principalobjection is that the looping of the wires is very likely to break thei
