In this distress, the wind still blowing very hard, one of our men early in the morning, cry d out, land ; and we had no sooner run out of the cabbin to look out in hopes of seeing where abouts in the world we were ; but the ship struck upon a sand, and in a moment her motion being so stopp d, the sea broke over her in such a manner, that we expected we should all have perish d immediately, and we were immediately driven into our close quarters to shelter us the very foam and sprye of the sea
我們知道，我們的船已支持不了幾分鐘了，隨時都可能被撞成碎片，除非出現奇跡，風勢會突然停息。總之，我們大家坐在一起，面面相覷，時刻等待著死亡的來臨，準備去另一個世界，因為，在這個世界上，我們已無能為力了。這時，船沒有像我們所擔心的那樣被撞得粉碎，同時風勢也漸漸減弱，使我們稍感安慰。
