The refrigerating plant is in duplicate, located on berth deck and has an aygre- gate capacity of two tons per day. An air compressor of 50 ft. per minute ca- pacity is supplied for furnishing air for pneumatic tools and for blowing boiler tubes. The general construction of the hull is clearly shown in the illustrations as well as the method of handling coal, either to the ship's bunkers or to other vessels. Working all hatches it is estimated that coal can be transferred at the rat of 100 tons per hour. The Vestal was launched May 19, 1908, but has not yet had her dock trials, although reported 98.6 per cent completed for several months past, and her steering gear and much of her equipment were incomplete Sept. 1.
