Where Upkeep Counts Most Twelve million miles of wire, connecting cities,villages, farms; running under busy streets and across trackless prairies; these are the Bell Telephone's ave nues of speech. These twelve million miles of wire, throughout every foot of their length, must be kept elec trically capable. A few drops of water within a cable may cut off a thousand subscribers. A line snapped by storm may isolate a district. A wet leaf touching a wire may stop service. In most kinds of OE t Sys~i ~ work the lessening of efficiency means merely the lessening of service; but with the telephone, mechanical and electrical con ditions must be practically per fect to insure operation. The most delicate electrical currents in use are those of the telephone, and inspection must be ceaseless that the lines may be kept in constant readiness. These conditions and costs must be met to provide this high standard of service needed and demanded by the Ameri can people.
