A modification of this method consists in plac-ing the required number of rubber-covered wires of No. 19 or gauge in a lead tube, such as to very loosely hold the wires, andfilling this tube with a compound of the same nature as that usedin pothead work. This pipe cable is tapped on to the main cablewith an ordinary Y splice, and moisture is prevented from enteringthe main cable by the sealing compound in the lead pipe. No otherseal is then necessary for the cable. In Fig. 607 such taps are. Sections Leadwrapjrin FIG. 610.—DETAILS OF CABLE TERMINAL. shown, these being used by Mr. L. W. Stanton in some of his recentwork. The details of the wire joint used in making Y splices areshown in Fig. 608. Where the cable is terminated by means of a pothead, or someform of box terminal, some housing must be provided for out-of-door terminals for the conductors to which the external circuits areto be Sometimes this housing assumes the form of a cylin-drical can of galvanized iron, as in the case shown in Fig. 607, andis better illustrated for a large terminal in Fig. 609. Whore apothead is used the general practice is to support it in an uprightposition on the pole, having its upper end extending into a woodencable box containing conductor strips, lo which the wires leadingfrom the pothead and those leading to the outside circuits may be 832 AMERICAN TELEPHONE PRACTICE. joined. This construction is applied to a multiple tap as shown indetail in Fig. 610, this being the sta
