p of the General Electric Company. From this terminal house thetwo 30,000-volt circuits cross River Road, Schenectady, by meansof si.x insulated cables, and enter the tower on a transformer housethat stands in the yard of the electric works. In this house arelocated transformers that lower the pressure of the transmittedenergy to 10,000 volts, and from these transformers the secondarycircuits pass at once to the switchboard in what is known as powerstation No. 13, which is nearby. At this switchboard the io,ooo-volt current is distributed throughtransformers to four rotary converters, to a motor-generator, to ashop-testing circuit, and through several cables to the new DockStreet sub-station of the Schenectady Railway Company. Fromthis sub-station both the railway system of this company extendingto Albany and Troy, and also the local system of light and powerin Schenectady are supplied with current, as described in the Elec-TRIC.11L World and Engineer of May 14, 1904. The lines to the

Between Spier Falls and the General Electric Works there aretwo three-phase, 40-cycle, 30,000-volt circuits. Both of these cir-cuits are composed of medium hard bare copper wires, the size ofwire in one circuit being i/o and in the other circuit 3/000 B. & S.gauge. At Alplaus switch house through which these lines passat a point about five miles north of the General Electric Works, theyare joined by a three-phase circuit of No. 3/0 wire from the Mechan-icville water power station. By connections at this switch houseenergy from Spier Falls may pass to the General Electric Worksover one of the two circuits, and energy from Mechanicville over theother, or both circuits may transmit the Spier Falls power. After crossing the Mohawk River and the Erie Canal the twocircuits of bare wires from A
