A Handy Bridge.
To' span a stream with a light bridge, that would catry two men at once, and, if carefully set up would last for years, take three or four strands of No 1 twisted galvanised wire, each the proper length to span the stream ; these to have eyelets let in at each end. Strain the wires with bolts and screws to a sleeper on each side, the wires to be from three po four inches apart; the sleepers to be kept in position by two upright sleepers let; into the ground on each bank. Two more lengths of wire, crossing the tops of these uprights and fastened to strong stakes in the ground would form a hand rail. Staple narrow boards 3 inches wide on to the wires of the bridge by driving underneath small staples into the boards, embracing one of the wires with each ; iJbeee boards to be kept an inch apart by ■wooden stops. The wires on which the lioa/rds rest could be tightened at pleasure by the aerews and bolts by which they are Attached to the sleepers.
