Pole Goes Up: A Detroit Edison utility pole digger is in position (left) to gouge a hole for a 70-foot pole that gets "planted" (center) [this photo] and finally straightened (right). The utility spends about $600,000 a year for poles, transmission lines and other equipment to extend service in the 1,200-square-mile district.

120,000 Volts: This is a scene at Detroit Edison's Superior Station, near Ypsilanti, where three 120,000 volt power lines converge to furnish power to the firm's Ann Arbor district. Any two of the three master lines could be cut without disrupting service.

Hydroelectric Power: Up to 38,000,000 of 646,481,000 kilowatt hours used last year came from a chain of four Detroit Edison hydroelectric plants on the Huron River. They are similar to this one at Superior Station near Ypsilanti. Most of the electricity used in the Ann Arbor district comes from sources near Detroit.

Emergency: A lineman cuts power and ground wires to a house which was aflame during a fire recently at Delhi in Scio township. Service crews and linemen are on 24-hour-a-day call to respond to this type and other emergencies.

The Past Reappears: Something missing from the Ann Arbor scene for many years--streetcar tracks--has made a limited reappearance. Streetcars went out of service here about a quarter of a century ago. The tracks shown were uncovered during work involved in widening and resurfacing S. State St. in the campus area. George H. Sandenburgh, superintendent of the city's Department of Public Works, says these tracks probably are the last ones remaining. Others were removed years ago.
