"The Commander," Lieutenant Gerdts said, "had charge of the first sambuk; I of the second, which was the larger of the two, for we had four sick men aboard. At first everything went nicely for three days. For the most part I could see the sails of the first ship ahead of me. On the third day I received orders to draw nearer and to remain in the vicinity of the first boat, because its pilot was sailing less skillfully than mine. Suddenly, in the twilight, I felt a shock, then another, and still another. The water poured in rapidly. I had run upon the reef of a small island, where the smaller sambuk was able barely to pass because it had a foot less draught than mine. Soon my ship was quite full, listed over, and all of us--twenty-eight men--had to sit on the uptilted edge of the boat. The little island lies at Jesirat Marka, 200 miles north of Jebaua. To be sure, an Arab boat lay near by, but they did not know us. Nobody could help us. If the Commander had not changed the order a few hours before and asked us to sail up closer, we would probably have drowned on this coral reef--certainly would have died of thirst. Moreover, the waters thereabouts are full of sharks, and the evening was so squally that our stranded boat was raised and banged with every wave. We could scarcely move, and the other boat was nowhere in sight. And now it grew dark. At this stage I began to build a raft of spars and old pieces of wood, that might at all events keep us afloat.
