After we had fisht some time and catcht nothing, for when I had Fish on my Hook, I would not pull them up, that he might not see them; I said to the Moor, this will not do, our Master will not be thus serv'd, we must stand farther off: He thinking no harm agreed, and being in the head of the Boat set the Sails; and as I had the Helm I run she Boat out near a League farther, and then brought her too as if I would fish; when giving the Boy the Helm, I stept forward to where the Moor was, and making as if I stoopt for something behind him, I took him by Surprize with my Arm under his Twist, and tost him clear over-board into the Sea; he rise immediately, for he swam like a Cork, and call'd to me, begg'd to be taken in, told me he would go all over the World with me; he swam so strong after the oat that he would have reacht me very quickly, there being but little Wind; upon which I stept into the Cabbin and fetching one of the Fowling-pieces, I presented it at him, and told him, I had done him no hurt, and if he would be quiet I would do him none; but said I, you swim well enough to reach to the Shoar, and the Sea is calm, make the est of your Way to Shoar and I will do you no harm, but if you come near the Boat I'll shoot you thro' the Head; for I'm resolved to have my Liberty; so he turn'd himself about and swam for the Shoar, and I make no doubt but he reacht it with Ease, for he was an Excellent Swimmer.

我们钓了一会儿鱼，一条也没有钓到；因为即使鱼儿上钩，我也不钓上来，免得让那摩尔人看见。然后，我对他说，这样下去可不行，我们拿什么款待主人呢？我们得走远一点。他一想这样做也无妨，就同意了。他在船头，就张起了帆；我在船尾掌舵。就这样我们把船驶出了约三海里，然后就把船停下，好像又要准备捕鱼似的。我把舵交给摩尔小孩，自己向船头摩尔人站的地方走去。我弯下腰来，装作好像在他身后找什么东西似的。突然，我趁其不备，用手臂猛地在他裤裆下一撞，把他一下推入海里。这个摩尔人是个游泳高手，一下子就浮出海面。他向我呼救，求我让他上船，并说他愿追随我走遍天涯海角。他在水里像鱼，游得极快，而这时风不大，小船行驶速度很慢，眼看他很快就会赶上来。我走进船舱，拿起一支鸟枪。我把枪对准了摩尔人，并对他说我并没想伤害他，如果他不胡闹，也不会伤害他。我说：&你泅水泅得很好，你完全可以泅回岸去。现在海上风平浪静，就赶快泅回去吧。我是不会伤害你的。要是你靠近我的船，那我就打穿你的脑袋！我已决心逃跑争取自由了！&他立即转身向海岸方向游回去。我毫不怀疑，他必然能安抵海岸，因为他游泳的本领确实不赖。
