1. Great Training Jetty at the Mouth of the Columbia River, Oregon
Description
2 p. 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. Messrs. M. J. Kinney and Robert Gibson are thanked for the accompanying illustrations and data used in the article. The five photographs show lowering of "mattresses" at the end of the jetty; a train load of rock starting its run out; loading rock onto the dump-cars at the jetty dock; the jet pile-driver used in constructing the trestle; and dumping rocks after the "mattresses" have been lowered.
