The coal capacity is 850 tons on normal displacement,which gives the ship a cruising range of about 3,000 knotsat full speed and of 10,000 knots at a lo-knot speed. On the trial trips the engines of the Edgar developed10,178 H.P. with natural draft. With forced draft, on afour hours trial, they averaged 13,101 H.P., and gave theship an average speed of 20 97 knots an hour. The boil-ers gave much more satisfactory results than in some otherships lately tried, showing no signs of weakness underforced draft. The artificial draft is on the closed stoke-hold system. The cruisers of which the Edgar is a type are lightervessels than the .VVa/ York of our own Navy, having noarmor belt.
