Page 33 of a journal article giving some history and financial information, as well as a great deal of construction detail, for the jetty built at the mouth of the Columbia River. The work of the pile-driver and use of railroad cars to carry construction supplies on the miles-long trestle are described. The photographs show lowering of "mattresses" at the end of the jetty, a train load of rock starting its run out, and loading rock onto the dump-cars at the jetty dock.
