In February, 1918, the chaser fleet was preparing for the trip across the Atlantic. Among the documents issued to the commanders of the chasers was a manual, "110-Foot U.S. Submarine Chaser - Instructions, Care and Operation of Machinery Plant." This document, dated February 14, 1918, is an addendum to that document.

Note: This document was bound by means of a brass rivet, which still holds all but the last two pages together. What you see along the top of pages 1 through 5 is the edge of the cover page, which has been rotated up for the scan.
