I was now recover'd from my Surprize, and began to look round me, when I found the Cave was but very small, that is to say, it might be about twelve Foot over, but in no manner of Shape, either round or square, no Hands having ever been employ'd in making it, but those of meer Nature: I observ'd also, that there was a Place at the farther Side of it, that went in farther, but was so low, that it requir'd me to creep upon my Hands and Knees to go into it, and whither I went I knew not; so having no Candle, I gave it over for some Time; but resolv'd to come again the next Day, provided with Candles, and a Tinder-box, which I had made of the Lock of one of the Muskets, with some wild-fire in the Pan.

由于我一直生活在危险之中，因而日夜忧虑，寝食不安，这就扼杀了我为使自己生活舒适方便的发明创造能力。如果我坦诚承认这一点，读者一定不会感到奇怪。我当前最迫切需要解决的是自己的安全问题，而不是食物问题。我连一个钉子都不敢钉，一块木头都不敢劈，生怕声音被别人听见；同样，我更不敢开枪了。尤其叫我担心的是生火这件事，唯恐烟火在白天老远就被人看见而把自己暴露。因此，我把一切需要生火的事，如用锅子烧东西或抽烟斗等都转移到我那林间别墅去做。在那儿，我呆了一段时期之后，发现了一个天然地穴，这使我感到无限的欣慰。地穴很深。我敢保证，即使野人来到洞口，也不敢进去。说实在的，一般人谁都不敢进去，只有像我这样一心一意想寻找安全的藏身之所才会冒险深入。

On the other hand, a higher frequency of CCR-64I allele was also observed in HIV-1 uninfected individuals who were heterosexually exposed to HIV-positive index partners (p=0.164), but most of the reports didn't support this result.
