In thiscase the pull of the guys was at a little more than aright angles to the holes, sothe tendency was to pull thebolt in rather than out. Inany such case a sharp sandfilling reasonably well tampedin would have served aswell. Indeed, if the pull isagainst the hole, no filling atall would have served as wellas the cement, and would saveits cost, but it is hardly thebest treatment. The guy itself is attachedto the anchor rod, what-ever the type of anchor, byan eye formed around a gal-vanized or sherardized thim-ble. At one time the usualmethod of securing this at-tachment was by wrapping the. FIG. 11—GUY INSULATION, PORCELAIN FIG. 12—GUY MARKERS ON 11,000-VOLTLINE, C, M. & ST. P.

Whilethis, the close tie, is considered by many as lesslikely to slip than the three-bolt clamp tie, this beliefis due largely to the action of clamps of poor design. Properly made, the latter tie, which is now thestandard of the telegraph and telephone companies, theN. E. L. A., and the A. E. R. A., will hold until the cowscome home. With it, even if the clamp is n
