The last Time of these two had well near been fatal to me; the Sea having hurried me along as before, landed me, rather dash'd me against a Piece of a Rock, and that with such Force, as it left me senseless, and indeed helpless, as my own Deliverance; for the Blow taking my Side and east, beat the Breath as it were quite out of my Body; and it returned again immediately, I must have been strangled in the Water; but I recover'd a little before the turn of the Waves, and seeing I should be cover'd again with the Water, I resolv'd to hold fast by a Piece of the Rock, and so to hold my Breath, if possible, till the Wave went back; now as the Waves were not so high as at first, being nearer Land, I held my Hold till the Wave abated, and then fetch'd another Run, which brought me so near the Shore, that the next Wave, tho' it went over me, yet did not so swallow me up as to carry me away, and the next run I took, I got to the main Land, where, to my great Comfort, I clamber'd up the Clifts of the Shore, and sat me down upon the Grass, free from Danger, and quite out of the Reach of the Water.

这两次大浪的冲击，后一次几乎要了我的命，因为海浪把我向前推时，把我冲撞到一块岩石上，使我立即失去了知觉，动弹不得。原来这一撞，正好撞在我胸口上，使我几乎透不过起来。假如此时再来一个浪头，我必定憋死在水里了。好在第二个浪头打来之前我已苏醒，看到情势危急，自己必为海水吞没，就决心紧抱岩石，等海水一退，又往前狂奔一阵，跑近了海岸。后一个浪头赶来时，只从我头上盖了过去，已无力把我吞没或卷走了。我又继续向前跑，终于跑到岸边，攀上岸上的岩石，在草地上坐了下来。这时，我总算脱离了危险，海浪已不可能再袭击我了，心里感到无限的宽慰。
