I started up in the greatest hast imaginable, and in a trice clapt my ladder to the middle place of the rock, and pull d it after me, and mounting it the second time, got to the top of the hill, the very moment, that a flash of fire bid me listen for a second gun, which accordingly, in about half a minute i heard ; and by the sound, knew that it was from that part of the sea where i was driven down the current in my boat
聽到槍聲后，我一躍而起，轉眼之間就把梯子豎在半山上，登上半山的坡坎后，又把梯子提起來架在坡坎上，最後爬上了山頂。就在這一剎那，我又看見火光一閃，知道第二槍又要響了果然不出所料，半分鐘之後，又聽到了槍聲。從那聲音判斷，知道槍聲正是從我上回坐船被急流沖走的那一帶海上傳來的。 -
