Gulliver's Travels Full Text: Part 4, Chapter 8 : Page 2
By what I could discover, the _Yahoos_ appear to be the most unteachable of all animals: their capacity never reaching higher than to draw or carry burdens. Yet I am of opinion, this defect arises chiefly from a perverse, restive disposition; for they are cunning, malicious, treacherous, and revengeful. They are strong and hardy, but of a cowardly spirit, and, by consequence, insolent, abject, and cruel. It is observed, that the red haired of both sexes are more libidinous and mischievous than the rest, whom yet they much exceed in strength and activity.
The _Houyhnhnms_ keep the _Yahoos_ for present use in huts not far from the house; but the rest are sent abroad to certain fields, where they dig up roots, eat several kinds of herbs, and search about for carrion, or sometimes catch weasels and _luhimuhs_ (a sort of wild rat), which they greedily devour. Nature has taught them to dig deep holes with their nails on the side of a rising ground, wherein they lie by themselves; only the kennels of the females are larger, sufficient to hold two or three cubs.
They swim from their infancy like frogs, and are able to continue long under water, where they often take fish, which the females carry home to their young. And, upon this occasion, I hope the reader will pardon my relating an odd adventure.
Being one day abroad with my protector the sorrel nag, and the weather exceeding hot, I entreated him to let me bathe in a river that was near. He consented, and I immediately stripped myself stark naked, and went down softly into the stream. It happened that a young female _Yahoo_, standing behind a bank, saw the whole proceeding, and inflamed by desire, as the nag and I conjectured, came running with all speed, and leaped into the water, within five yards of the place where I bathed. I was never in my life so terribly frightened. The nag was grazing at some distance, not suspecting any harm. She embraced me after a most fulsome manner. I roared as loud as I could, and the nag came galloping towards me, whereupon she quitted her grasp, with the utmost reluctancy, and leaped upon the opposite bank, where she stood gazing and howling all the time I was putting on my clothes.
