The work of telephone company construction crews is almost entirely outdoors. The linemen work in gangs under a foreman, and generally not far from their homes. During the summer, however, they travel about putting up through lines of poles and trunk wires. If the men cannot find accommodations in some house during such times, they camp out. After a great storm, linemen are called from every section with all possible speed to repair any damage which may have been done.
