��Three Slender Wires Form a Bridge
THREE wires make a bridge in Maine. It is probably the cheap- est one ever made, if the good old sub- terfuge of a log thrown across a stream is excepted, but it is as serviceable as concrete for spamiing the fifty-foot creek over which it does duty.

As it is, the company had a large number of cars in its own garage with a staff of re])airmen. It was necessary only to add a few men to the regular staff to repair the damage caused by accidents.
