and up the course, against and with the tide, she was found to have made 10.78 knots per hour. Her mean speed for three runs made as required at maximum speed was a small fraction over 11 knots. In another exhibition' in semi- submerged or awash condition the Octo- pus attained a maximum speed of 9.98 knots. In order to enable the board to prepare her speed curve the boat made a series of surface runs at gradually re- duced speeds. In the first run awash, which was down the course, the Octopus had the tide in her favor, used only her electric motors and attained a speed of 11.05 knots, Up the course, against the tide, "her speed was 8.97 knots, the mean for this round trip being just about 10 knots. Going down again with the tide the Oc- topus made the run at the rate of 10.94 knots, which was surprising, as her own- ers had only claimed 10.5 knots for her in cruising trim. The second test of the Octopus oc- curred on May 8 and it is claimed that in this trial she made a world's record by attaining a speed of more than 10 knots under water. Three high-speed runs were made. un- der water, the first mile being covered at the rate of 10.15 knots; this was her maximum speed, the average being 10 - knots plus, a trifle less than made on May 3, while running awash. The conditions specified that she was to be at least 10 ft. below the surface but must show three feet of mast above the water. The submerged tests were fol- "TRAE Marine REVIEW made from her conning tower, after which she made another dive and an- other broach under the same conditions and in the same time.

An interesting feature of these tests was the use of submarine signal bells, one on the Octopus and one on the ten- der Starling, by which means communi- cation was kept up while the boat was submerged.
