But never was a fight managed so hardily, and in such a surprising manner, as that which followed between Friday and the bear, which gave us all (though at first we were surprised and afraid for him) the greatest diversion imaginable: as the bear is a heavy, clumsy creature, and does not gallop as the wolf does, who is swift, and light; so he has two particular qualities, which generally are the rule of his actions; first, as to men, who are not his proper prey; I say, not his proper prey; because though I cannot say what excessive hunger might do, which was now their case, the ground being all covered with snow; but as to men, he does not usually attempt them, unless they first attack him: on the contrary, if you meet him in the woods, if you don't meddle with him, he won't meddle with you; but then you must take care to be very civil to him, and give him the road; for he is a very nice gentleman, he won't go a step out of his way for a prince; nay, if you are really afraid, your best way is to look another way, and keep going on; for sometimes if you stop, and stand still, and look steadily at him, he takes it for an affront; but if you throw or toss any thing at him, and it hits him, though it were but a bit of a stick, as big as your finger, he takes it for an affront, and sets all his other business aside to pursue his revenge; for he will have satisfaction in point of honour; that is his first quality: the next is, that if he be once affronted, he will never leave you, night or day, till he has his revenge; but follows at a good round rate, till he overtakes you.

再没有什么战斗比"星期五"和大熊之间后来那场战斗更勇敢和更惊险的了。这场大战起初确实使我们感到很惊险，但最后却给了我们大家无比的娱乐。熊这种动物身体笨重，行动迟缓；不像狼那样一路小跑，又快又轻。因此熊具有两个特性，作为它的一般行动规则：第一、先说人，人不是熊的合适的猎物，我是说的"合适的猎物"；当然，像现在这种情况，地上全被大雪覆盖，熊极端饥饿时是否也会吃人，我就不敢说了。不过，人一般不要去攻击熊，除非熊首先攻击人；相反，要是你在树林里遇到熊，你不去惹它，它也不会惹你。不过你得特别小心，要对它特别客气，给它让路，因为它是一位非常可爱的绅士，就是王子，熊也不会给他让开一步的；如果你真的害怕，最好不要看它，继续走你的路。如果你停下来，站着不动，盯着看它，它就认为是对它的挑衅。如果你向它扔什么东西，打中了它，哪怕是一根只有手指头粗的棍子，它也认为是对它一种挑衅，就会不顾一切，实行报复；因为只有把荣誉挣回来他才会感到满足。这是熊的第一个特性。第二个特性是：熊一旦受到挑衅，就会日夜跟着你，直到报完了仇；哪怕绕上许多路，也要跟着你，直到把你抓住。
