Board of Water Supply. Laying water distribution pipes. T. A. Gillespie Company, contractor. View on 86th Street, looking east from a point about 100 feet east of 4th Avenue, showing the trench opening as far as Fort Hamilton Parkway and the neat piling of the excavated material by the trenching machine. Note the pipe laying in progress and, also, that the pipe laying derricks are guyed by ropes to prevent overturning. Boy sitting on pile of excavated material. August 27, 1923.
