Excerpt from The Air and Ventilation of SubwaysThis volume is the outcome of studies carried on for two and one-half years for the Board of Rapid Transit Railroad Commissioners for the City of New York and, after that board went out of existence, for the Interborough Rapid Transit Company to whom the first New York subway is leased. The work was begun in the summer of 1905 and concluded in 1907.The original data covering about 2000 pages have never been published, although reports summarizing many of the facts have appeared in the official transactions of the Rapid Transit Commissioners or been read by the author before the Society of Arts of Boston, the New York Academy Of Medicine or elsewhere.At the conclusion of the investigations it seemed desir able to have some of these reports bound together for private circulation, but it was finally decided to put the work into somewhat more extended form and offer it to the general public.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
