"Oh, Mr. Hythe," continued the latter. "I want to send a couple of men down to report on the position of the submarine. If she’s anchored, get them to find out in which direction her cable leads and we can then creep for it. Also I want to ascertain whether it be possible to lower the bight of a chain under her bow and stern. If that can be done I’ll signal to the Dockyard for a couple of lighters, and we’ll lift the craft with the rising tide and take her straight into the Hamoaze. But mind, Mr. Hythe, I wish it to be distinctly understood that volunteers only are required for this service." "I should like to descend, sir." "You! Why I thought, by Jove, you had enough of it on the last occasion you encountered the submarine, judging by all accounts. But of course, I should be glad to accept your offer. Take two men with you." The sub again saluted, and on gaining the quarter deck ordered the bo’s’un’s mate to pipe away the diving-party. Of the qualified divers every man-jack expressed his desire, as vehemently as the presence of the officers permitted, to go down. Hythe would have much preferred to have taken Moy and Banks, who at his request had been transferred from the "flagship, but favouritism he strongly set his face against. "Numbers one and two front rank men, fall out." Number one was a tall, broad-shouldered Irishman named O’Shaunessey, a man who still retained the Wexford brogue. Number two was a dapper little Cockney, Price by name, who had the distinction of holding the Navy record for deep-sea diving. "Look here, Price," said the sub, "I’m going down too; but I want you to clearly understand what to do. I will try to locate the Submarine, and see if there is any possibility of raising it by means of a grapnel. You I want to get as close to the bows as you can without much chance of being seen and report by telephone what forefoot she has, if any, and if there’s any chance of slinging her at that end. O’Shaunessey, I want you to examine the after-end, and find out what overhang she has; also whether her propellers are foul of anything." "Hurry up, there!" ordered Captain Tarfag. He was naturally anxious that his prey should not escape him, for, although the strain on the picquet boat’s grapnel-line was maintained, the bubbles no longer rose from the enmeshed submarine. Hythe was the first to descend, from a boat lowered from the "Investigator." The conditions beneath the surface were far more favourable than on the occasion of his descent at Spithead, for the bottom was of firm white sand, and the tidal current was barely a quarter of a knot. Ere he had traversed fifty yards an ill-defined mass loomed up ahead of him. It was the submarine, exaggerated out of all proportion by the refractive properties of the water. With rapidly beating heart the sub continued to advance. Suddenly he saw a figure in diver’s dress approaching. He stopped. The stranger stopped too.
