§ 20. Mr. HORE-BELISHAasked the First Lord of the Admiralty whether any new and improved device whereby a submarine may make its position known in the event of its being sunk has been fitted to submarines since the loss of the M1; and whether experiments have been made with any new device?
§ Mr. BRIDGEMANThe answer to both parts of the question is in the negative. No device has yet been invented which improves upon the existing arrangements of which I gave some particulars to the hon. and gallant Member in my reply of 19th November last.
§ Mr. HORE-BELISHASince that date have no experiments whatever been made?
§ Mr. BRIDGEMANWe have made our own experiments on suggestions made to us; other suggestions have either been considered before or are not considered of sufficient value to go to the expense of experiments.
