The ground selected was especially adapted to extended order. TRENCH CONSTRUCTION AND BAYONET ASSAULT. The exigencies of trench warfare, as waged in the World War, resulted in rendering the bayonet exercise prescribed in the drill regulations obso- lete. It was not, however, until about the time that the second draft was imminent that the new method of fighting with the bayonet was published. The officers of the company immediately decided to carry the instruction beyond what had been originally contemplated. The Spring Valley Water Company was appealed to set aside a piece of ground and to permit the construction on it of trenches, and the necessary equipment for a bayonet assault course. Permission was readily given, and on Sunday October 6, 1918, after a drill in extended order over the brush covered sand dunes at the western extremity of the Lake Merced tract, the company proceeded to the ground selected for the trenches and began to work. The United Railroads donated to the company the use of a dozen picks and a dozen shovels. The San Francisco Retail Lumber Yard gave the lumber necessary which amounted to about two thousand feet. The Pacific Wire and Steel Works contributed the wire and the Palace Hardware Company and W. A. Plummer Manufacturing Company made substantial discounts in their bills for hardware and canvas dummies respectively. Messrs. R. H. Swayne, George W. Lamb and T. H. Palache contributed money toward defraying the expenses. The work was continued on Sundays October 13, 20 and 27, November 10 and 17, 1918, on which last date the work was practically completed.
