Sometime I contriv'd to dig a Hole under the Place where they made their Fire, and put in five or six Pound of Gun-powder, which when they kindled their Fire, would consequently take Fire, and blow up all that was near it; but as in the first Place I should be very loth to wast so much Powder upon them, my Store being now within the Quantity of one Barrel; so neither could I be sure of its going off' at any certain Time, when it might surprise them, and at best, that it would do little more than just blow the Fire about their Ears and fright them, but not sufficient to make them forsake the Place; so I laid it aside, and then propos'd, that I would place my self in Ambush, in some convenient Place, with my three Guns, all double loaded; and in the middle of their bloody Ceremony, let fly at them, when I should be sure to kill or wound perhaps two or three at every shoot; and then falling in upon them with my three Pistols, and my Sword, I made no doubt, but that if there was twenty I should kill them all: This Fancy pleas'd my Thoughts for some Weeks, and I was so full of it, that I often dream'd of it; and sometimes that I was just going to let fly at them in my Sleep.

就我目前的境况而言，我其实不缺多少东西。可是，我总感到，由于受到那些野蛮的食人生番的惊吓，因而时时为自己的安全而担惊受怕。以往，为使自己的生活过得舒服，我充分发挥了创造发明的才能，但现在就无法充分发挥了。我本来有一个煞费苦心的计划，想试验一下能否把大麦制成麦芽，再用麦芽来酿起酒。现在，这一计划也放弃了。当然，这实在也是一个荒唐的念头，连我自己也经常责备自己把事情想得太简单了。因为我不久就看出，许多酿造啤酒必不可少的材料我都没有，也无法自己制造。首先，没有啤酒桶。前面说过，我曾尝试做木桶，但怎么也做不好。我曾花了许多天、甚至许多星期、许多个月，结果还是没有成功。其次，没有啤酒花使酒经久不坏，没有酵母发酵，没有铜锅铜罐煮沸。可是，尽管如此，我还是坚信，要是没有对食人生番的惊惧和恐怖，我早就可能着手去做了，甚至也许已做成功了。

Thus the law of supply and demand of labor is kept in the right rut, the oscillation of wages is penned within limits satisfactory to capitalist exploitation, and lastly, the social dependence of the laborer on the capitalist, that indispensable requisite, is secured; an unmistakable relation of dependence, which the smug political economist, at home, in the mother-country, can transmogrify into one of free contract between buyer and seller, between equally independent owners of commodities, the owner of the commodity capital and the owner of the commodity labor.

这样，劳动力的供求规律就保持在正常的轨道上，劳动力的变动就限制在资本主义剥削所容许的范围内，最后，工人对资本家必不可少的社会从属性即绝对的从属关系得到保证。政治经济学家本国，即宗主国，可以花言巧语地把这样绝对的从属关系描绘成买者同卖者之间的自由契约关系。
