The foreman addressed rose from his seat and called to his half-dozen caulkers sitting at hand. The boat dived easily on while the men passed fore and aft painting red dabs on rivets and seams overhead where trickles of water spoke of red-lead or packing which was not yet "set" or in condition to face the pressures of active service. Their tour over, the party settled back to their stations, and at a nod and gesture from the Captain the hydroplane men tilted the bow slightly down again for further descent. At a hundred and twenty feet the order came for the motors to stop, and with failing headway the boat sank gently down. One or two men (naval as well as civilian) reached out a hand to grasp for support as they stood, for the moment before touching bottom is always one of slight uncertainty; for, however reliable the chart, it is yet possible to bounce roughly on these occasions on such unexpected obstacles as isolated rocks or even wrecks. But there was no need for bracing against the unexpected to-day. The boat touched and slid on to a standstill so gently and imperceptibly that her Captain watched the gauge for at least thirty seconds after she had landed, with the suspicion that she might be only "statically trimmed" and that she had a fathom or two farther yet to fall. Then he spoke--"Flood A--hydroplanes amidships." There came a bubbling roar from the vent of A, well forward, and then the clang of a heavy "water-hammer" in the pipe as the tank filled. The boat lay now as he intended her to do, bedded with negative buoyancy and with her bows well down, so that her screws and rudder were clear of the oozy mud in which she lay. "Carry on--all hands--and look for leaks." The caulkers did not linger over the task. They did not (and small blame to them, for they were not case-hardened to the situation) relish the idea of staying longer than was necessary at a hundred and thirty-six feet by gauge and with a pressure of sixty pounds to the square inch trying to force the round steel hull inwards on itself. In a quarter of an hour they reported "All leaks located and marked." But their ordeal was not yet over. The gloomy-eyed First Lieutenant (a pessimist, as all First Lieutenants should be) had found a new leak right aft, and the Captain was called into consultation over it. For ten minutes more the two officers conversed and searched, then came leisurely forward again. "That's all right, I think," said the Captain cheerfully. "Anybody want to look round any more? I can stay down here while they do--there's no hurry, you know." There was an enthusiastic chorus from a group of overseers and officials--"Not at all, not at _all_, we're _quite_ satisfied--quite...." The Commander, who throughout the dive had sat unmoving by the periscope, notebook in hand and his eyes half closed, allowed himself a faint smile and a lazy yawn. "Blow on A--fifty pounds--Blow one and two externals."
