The pumps, orders had been given to start them directly the leak was noticed. Three minutes later, the machinery and the pipes, fouled with grain, refused to work. They saw bubbles, steam, a trickle of water that presently stopped, and lumps of wet grain that some one might have chewed together, and spat forth again. Idaho did a lot of signalling in code to the guide ship of the convoy. The _Sebastopol_ began to drop behind. An order being given to sleep up on the boat deck so as to be ready to leave at any instant, the men dragged their bedding to whatever shelter they could find. The captain appeared never to take any time off for sleep. Day after day, through heavy seas, under a sky torn and dirty as a rag, the old _Sebastopol_ listing badly and sodden as cold porridge, carried her precious cargo to the waiting and hungry east. Giving up all hope of keeping up with her sisters, she fell behind, now straggling ten, now fifteen miles astern. At length the weather changed; the sea became smooth, blue and sparkling, the sky radiant and clear. Then the destroyers came. There was a parley, and the other vessels of the convoy zigzagged wildly for a while in order to allow the _Sebastopol_ to catch up. But in spite of all attempts, the old ship fell behind again and was suffered to do so, lest the others, compelled to adopt her slow speed, be seriously handicapped in their race down the gauntlet. Then it was discovered that the leak had gained alarmingly; there was even talk of abandoning the vessel and taking to the boats. A try was made to pump out the boat with an ancient hand engine. The contrivance clogged almost at once. According to Idaho, it was much like trying to pump out a thick bran mash such as they give sick calves. And they were only two days from land. Barely afloat, just crawling, and with the submarine zone ahead of them.... But the gods were kind, and the old boat and the solitary destroyer went down the Channel and across the Irish Sea as safely as clockwork toys across a garden pool. Yet they passed quite a tidy lot of wreckage. Nearer ... nearer all the time, till late one afternoon two big tugs raced to meet them at the mouth of a giant estuary. The _Sebastopol_ was at the end of her tether. Another day, and it would have been a case of taking to the boats. The tugs hurried her into a waiting dry dock. Idaho, his papers signed, his bag upon his shoulder, got into a little tender which was to take him over to the harbour landing. Looking up, he saw some of the crew leaning over the rail.... They grinned with friendly, soot-streaked faces, waved their arms.... The _Sebastopol_ was safe, the rich cargo of grain, the life-giving yellow grain was safe.... The tug slid off into the busy, noisy riverway. And thus came Idaho of the Armed Guard to the Beleaguered Isles. XXXII COLLISION
