Without touching even once the tramp crossed the dangerous patch, and was soon breasting the rapidly-increasing current. The river at this point was about 180 yards in width, and carried a depth of 30 to 40 feet for twelve miles from its mouth. On either side the banks were overhung with mangroves and coco-nut palms, from which myriads of birds, aroused by the unfamiliar noise of the tramp, rose screeching in the sultry air. The surface of the river was dotted with black objects resembling water-logged trunks of trees, but on the _Myra's_ approach the seemingly inanimate objects were endowed with life and activity. They were hippopotami, that literally swarmed in the turgid water. Having, as he imagined, navigated the _Myra_ beyond reach of the British cruisers, Unter-leutnant Klick ordered several of the crew of the captured tramp on deck, and informed them that they were in future to assist in working the ship. Should any attempt to recover the vessel be made, the offence would be punishable with death. He also pointed out the impracticability of escape, since the river was infested with hippopotami, and the forests with fierce animals. Just before sunset, the _Myra_ brought up at a distance of about seven miles from the mouth of the river. The flood-tide, accompanied by a distinct bore, had now set in, and since the river was hardly wide enough to allow the tramp to swing, an anchor was let go astern and twice the amount of cable necessary paid out. Then, directly the vessel's way was stopped, the bower-anchor was let go from the bows. The stern cable was then hove inboard until the ship lay evenly between the two anchors. The _Myra_ had no stockless anchors, but those of the old Admiralty pattern. "By Jove! how strong the current runs here!" remarked O'Hara, as the two subs watched the yellow stream surge past the ship. "If the ground tackle carried away there would be a jamboree. A new channel wouldn't form in a couple of days here." Denbigh did not reply. He was mentally gauging the distance between the ship's side and the nearmost bank. "It's risky," he thought; "but there are no gains without pains. I'll have a shot at it to-night." On being ordered to retire to their cabin the two officers found that the mate was already there. As Denbigh and his chum entered, he hastily stowed something in his pocket, but finding that they were not any of the German crew he withdrew the article. It was a piece of soft wood about nine inches in length. "What's the game, Armstrong?" asked Denbigh.
