Blasting machines with three posts can be used with either twoor three leading wires. When used with two leading wires, onewire is connected to the middle post and the other to either one ofthe outside posts. When used with three leading wires, those from 96 EXPLOSIVES AND BLASTING SUPPLIES the two outside posts are connected to the electric fuzes on theends of the circuit, and that from the middle post is connec
