The corpse of a boy floated past the ship; a monstrous crocodile rushed at it with the speed of a greyhound, caught it and shook it, as a terrier dog does a rat. Others dashed at the prey, each with his powerful tail causing the water to churn and froth, as he furiously tore off a piece. In a few seconds it was all gone. The sight was frightful to behold. The Shire swarmed with crocodiles; we counted sixty-seven of these repulsive reptiles on a single bank, but they are not as fierce as they are in some rivers. "Crocodiles," says Captain Tuckey, "are so plentiful in the Congo, near the rapids, and so frequently carry off the women, who at daylight go down to the river for water, that, while they are filling their calabashes, one of the party is usually employed in throwing large stones into the water outside." Here, either a calabash on a long pole is used in drawing water, or a fence is planted. The natives eat the crocodile, but to us the idea of tasting the musky-scented, fishy-looking flesh carried the idea of cannibalism. Humboldt remarks, that in South America the alligators of some rivers are more dangerous than in others. Alligators differ from crocodiles in the fourth or canine tooth going into a hole or socket in the upper jaw, while in the crocodile it fits into a notch. The forefoot of the crocodile has five toes not webbed, the hindfoot has four toes which are webbed; in the alligator the web is altogether wanting. They are so much alike that they would no doubt breed together.
