Excerpt from The Subways and Tunnels of New York: Methods and Costs, With an Appendix on Tunneling Machinery and Methods and Tables of Engineering Data No record of tunneling under the rivers surrounding New York is complete without a tribute of admiration and respect to the genius and ability shown by the men who were the architects and builders. It has for a long time been an easy matter to tunnel through rock. The power drill simply added to the efficiency of rock tunneling and in doing this it was made possible to build great tunnels for railways, aqueducts, etc., within a reasonable time and at reasonable expense. To build and maintain tunnels through silt or other alluvial material, especially tunnels of large diameter, was a problem which had not been solved by engineers as late as 1874. At that time Mr. Delos E. Haskin came to New York from San Francisco, where he had made a fortune, every dollar of which he lost in an effort to prove the practicability of tunneling under the Hudson River and through the silt by means of compressed air. Though Haskin did not live to enjoy the fruits of his work, he proved the practicability of his scheme in a general way and to him belongs the credit as the genius who pushed the idea to the front. Next came Mr. Charles M. Jacobs, who combined the genius and enthusiasm of Haskin with the ability of the engineer. Mr. Jacobs built the first tunnel under the rivers about New York, namely, the East River Gas Tunnel from New York to Brooklyn. After this he took up with enthusiasm the completion of the old Haskin tunnels, maintaining with earnest zeal the practicability of the scheme, modified on lines of his own experience, until he succeeded in completing these and the Pennsylvania tunnels, which are described in this volume.
