The rails are laid on a foundationof 6 ins. of cement concrete, extending 2 ft. outside therails, and the paving consists of whinstone and granitesetts. OVERHEAD EQUIPMENT As will be seen by the illustrations, the overhead con-struction is carried out generally upon the lines which arefamiliar in America, but with that greater attention to de-. ENGINE AND GENERATOR SET tail and appearance which makes overhead construction inGreat Britain distinctly tasteful. Side-pole construction isprincipally used, though a small amount of center-polework has been found necessary. The Dickinson side-run-ning trolley, with side-pole construction, is used. Thepoles are of steel, drawn taper, 28 ft. to 30 ft. in length, thediameter at the base being 7 ins. The bracket constructiondeparts from the usual English practice, in the fact that castiron is used. The result, while giving an ample margin ofmechanical strength, has rendered possible a very orna-mental and artistic design, which is exceedingly handsomein appearance. The feeder system is exceedingly com-plete. The cables are insulated with vulcanized bitumen,protected by double braiding of hemp yarn, and are of thedrawn-in type, laid in Sykes patent conduits. The usualfeeder pillars are arranged at half-mile intervals, eachterminus being in telephonic communicat
