Special No. 00 figure eight trolley wire was used, support-ed by Keystone mechanical ears for straight line suspensionsand soldered ears for curve suspensions. Span constructionwas used for about half a mile, but along the county high-way where the track is at one side of a ,oO-foot street a singleline of poles was used with the bracket arm Improvements at Key West, Fla.—Plan of Span Wires and Piill-Offs for Three-Part Y. The regular form of construction was used with the bracketsas on the span work, except that a novel method of arrange-ment of anchor wires was adopted. The anchor wires at-tached to the strain anchors on the pole side run to the nextpoles in the usual fashion; the anchor wires on the outerside run to the ends of the next bracket arms on each sideof the anchors. Here they are attached to the usualturn buckles hooking into one eye of a double-eyed strapfitting over the end of the bracket arm. From the othereye and the turnbuckle attached thereto a stranded strainwire runs back to the second pole from the anchor. Tocounteract the uplift of the strain wires upon the bracketarms a piece of tubing is inserted in one leg of a 45-degreeY-fitting, the other leg of which is slipped over the bracketarm and bolted thereto.
