It was necessary to provide a machine shop for the repairsof the cars and motors, and this shop was located at RioPiedras. Here several lathes, a wheel press, forges, drillpresses, etc., are installed. The tools are motor driven. The road is managed under the supervision of the operatingdepartment of J. G. White & Company. C. F. Beanies, thelocal manager, is in active charge. ■ HINTS ON SHOP MANAGEMENT BY A REPAIR MAN. TRACK CONSTRUCTION ON THE CARATARA, SAN JUAN the residence and business houses of San Juan and Santurcewith 60-cycle 104-volt alternating current through transform-ers. The lighting current is distributed at 2200 volts. One of the most interesting features of the overhead con-struction at San Juan is the arrangement whereby all feedersand high-tension lines are carried on specially built trusses orcross-arms on the roofs of the houses. This condition wasnecessitated by the fact that the streets are too narrow to per-mit the erection of pole lines. The majority of the buildingsin the city are of brick, with flat roofs. The exterior walls,however, extend several feet above the roof level. To thesewalls are fastened the braces or trusses, so that the wires arecarried at a safe distance above the tops of the buildings. Thesecondary distribution is three-wire. Electricity ,is used bythe natives for both light and power to a surprising extent,largely on account of the
