One of the crocodiles which was shot had a piece snapped off the end of his tail, another had lost a forefoot in fighting; we saw actual leeches between the teeth, such as are mentioned by Herodotus, but we never witnessed the plover picking them out. Their greater fierceness in one part of the country than another is doubtless owing to a scarcity of fish; in fact, Captain Tuckey says, of that part of the Congo, mentioned above, "There are no fish here but catfish," and we found that the lake crocodiles, living in clear water, and with plenty of fish, scarcely ever attacked man. The Shire teems with fish of many different kinds. The only time, as already remarked, when its crocodiles are particularly to be dreaded, is when the river is in flood. Then the fish are driven from their usual haunts, and no game comes down to the river to drink, water being abundant in pools inland. Hunger now impels the crocodile to lie in wait for the women who come to draw water, and on the Zambesi numbers are carried off every year. The danger is not so great at other seasons; though it is never safe to bathe, or to stoop to drink, where one cannot see the bottom, especially in the evening. One of the Makololo ran down in the dusk of the river; and, as he was busy tossing the water to his mouth with his hand, in the manner peculiar to the natives, a crocodile rose suddenly from the bottom, and caught him by the hand. The limb of a tree was fortunately within reach, and he had presence of mind to lay hold of it. Both tugged and pulled; the crocodile for his dinner, and the man for dear life. For a time it appeared doubtful whether a dinner or a life was to be sacrificed; but the man held on, and the monster let the hand go, leaving the deep marks of his ugly teeth in it.
