The porcelain insulators are bushed with wood.(See Fig. 2.) For turning a square corner and for convenience inbranching the sub-feeders from the trunk-lines, thejunction frame was devised, mechanical details of which are shown in accompanying drawing, Fig. of wooden cross-arms, 4 inches x 4 inches x Yiinch angle iron is employed. Two long pieces carry theweight of the frame and connections, and two short oneson top of them transmit the stresses from the frameto the pole. The end-connectors of the cables areattached by double giant strain insulators to the. eyebolts in the sides of the frame. Electrical connec-tion is made by running a bus-bar around the top of theframe on top-groove insulators, into which run jump-ers from all the cables dead ended at the frame. The greatest care has been exercised in the erection ofthe guys and guy stubs which anchor the numerouscorner and junction poles along the trunk lines. Theguys for these poles are of ^ inch and Y inch galvan-ized wire rope, fastened with clamps and various styles are in vogue, the one preferred is theshort V-guy; that is, the point of the V where themain guy cable is attached is only 8 or 10 feet fromthe frame, and there is no tendency for the sides of theV to twist around each other at the point, as is the casewith a long V. At the stub, the main cable is attachedto a turnbuckle, of 1 inch to 1^2 inch iron, according tocircumstances: Some of the guy-stubs along the trunklines are of wood 14 inches x 14 inches yellow pine, setin 8 feet of concrete, and raking back
