The next Day after I came home to my Hutch with him, I began to consider where I should lodge him, and that I might do well for him, and yet be perfectly easy my self; I made a little Tent for him in the vacant Place between my two Fortifications, in the inside of the last, and in the outside of the first; and as there was a Door, or Entrance there into my Cave, I made a formal fram'd Door Case, and a Door to it of Boards, and set it up in the Passage, a little within the Entrance; and causing the Door to open on the inside, I barr'd it up in the Night, taking in my Ladders too; so that Friday could no way come at me in the inside of my innermost Wall, without making so much Noise in getting over, that it must needs waken me; for my first Wall had now a compleat Roof over it of long Poles, covering all my Tent, and leaning up to the side of the Hill, which was again laid cross with smaller Sticks instead of Laths, and then thatch'd over a great Thickness, with the Rice Straw, which was strong like Reeds; and at the Hole or Place which was left to go in or out by the Ladder, I had plac'd a kind of Trap-door, which if it had been attempted on the outside, would not have open'd at all, but would have fallen down, and made a great Noise; and as to Weapons, I took them all to my Side every Night.

应该说，我现在的裁缝手艺已相当不错了。另外，我又给了他一顶兔皮帽子，戴起来挺方便，样子也很时髦。现在，他的这身穿戴也还过得去了。他看到自己和主人几乎穿得一样好，心里十分高兴。说句实话，开始他刚穿上这些衣服时，深感行动不便；不但裤子穿起来感到很别扭，而且，背心的袖筒磨痛了他的肩膀和胳肢窝。后来我把那使他难受的地方略微放宽了一些，再加上对穿衣服也感到慢慢习惯了，他就喜欢上他的衣着了。回到家里第二天，我就考虑怎样安置星期五的问题。我又要让他住得好，又要保证自己绝对安全。为此，我在两道围墙之间的空地上，给他搭了一个小小的帐篷，也就是说，这小帐篷搭在内墙之外，外墙之内。在内墙上本来就有一个入口通进山洞。因此，我在入口处做了个门柜和一扇木板门。门是从里面开的。一到晚上，我就把门从里面闩上，同时把梯子也收了进来。这样，如果星期五想通过内墙来到我身边，就必然会弄出许多声响，也就一定会把我惊醒。
