Ch. I.] ALLIGATORS. 9
sand-bank that extends down to the mouth of the river, A long, deep branch from the river is a favourite resort for alligators. At the far end of a sand-spit, near where some low trees grew, I saw several dark objects lying close to the water on the shelving banks. They were alligators basking in the sun. As I approached, most of them crawled into the water. Mr. Hollenbeck had been down a few days before shooting at them with a rifle, to try to get a skull of one of the monsters, and I passed a dead one that he had shot. As I walked up the beach, I saw many that were not less than fifteen feet in length. One lay motionless, and thinking it was another dead one, I &as walking up to it, and had got within three yards, when I saw the film over its eye moving, otherwise it was quite still, and its teeth projecting beyond its lips added to its intense ugliness and appearance of death. There was no doubt, however, about the movement of the eye-covers, and I went back a short distance to look for a stick to throw at him; but when I turned again, he was just disappearing into the water. It is the habit of these animals to lie quite still, and catch animals that come near them. Whether or not he was waiting until I came within the swoop of his mighty tail I know not, but I had the feeling that I had escaped a great danger. It was curious that he should have been so bold only a few days after Mr. Hollenbeck had been down shooting at them. There were not less than twenty altogether, and they swam out into the middle of the inlet and floated about, looking like logs in the water, excepting that one stretched up his head and gave a bellow like a bull. They sometimes kill calves and young horses, and I was told of one that had seized a full-grown horse, but its
struggles being observed, some natives ran down and saved it from being pulled into tlie water and drowned. I heard several stories of people being killed by them, but only one was well authenticated. This was told me by the head of the excellent Moravian Mission, at Blewfields, who was a witness of the occurrence. He said that one Sunday, after service at their chapel at Blewfields, several of the youths went to bathe in the river, which was rather muddy at the time; the first to plunge in was a boy of twelve years of age, and he was immediately seized by a large alligator, and carried along under water. My informant and others followed in a canoe, and ultimately recovered the body, but life was extinct. The alligator cannot devour his prey beneath the water, but crawls on land with it after he has drowned it. They are said to catch wild pigs in the forest near the river by half burying themselves in the ground. The pigs come rooting amongst the soil, the alligator never moves until one gets within his reach, when'he seizes it and hurries off to the river with it. They are often seen in hot weather on logs or sand-spits lying with their mouths wide open. The natives say they are catching flies: that numbers are attracted by the saliva of the mouth, and that when sufficient are collected, the alligator closes his jaws upon them, but I do not know what reliance can be placed on the story. Probably it is an invention to account for the animals lying with their mouths open; as in all half-civilised countries I have visited I have found that the natives seldom admit they do not know the reason of anything, but will invent an explanation rather than acknowledge their ignorance.

I Found at Greytown the mail-boat of the Chontales Gold Mining Company, which came down monthly in charge of Captain Anderson, an Englishman who had knocked about all over the world. The crew consisted of four Mosquito negroes, who are celebrated on this coast for their skill as boatmen. Besides the crew, we were taking three other negroes up to the mines, and with my boxes we were rather uncomfortably crowded for a long journey. The canoe itself was made from the trunk of a cedar-tree (Ceclrela odorata). It had been hollowed out of a single log, and the sides afterwards, built up higher with planking. This makes a very strong boat, the strength and thickness being where it is most required, at the bottom, to withstand the thumping about amongst the rocks of the rapids. I was once in one, coming down a dangerous rapid on the river Gurupy, in Northern Brazil, when we were driven writh the full force of the boiling stream broadside upon a rock, with such, force that we were nearly all thrown down, but the strong canoe was uninjured, although no common boat could have stood the shock without being staved in.
Having determined to go up the river in this boat, we took provisions with us for the voyage, and one of the negroes agreed to act as cook. Having arranged everything, and breakfasted with my kind friends, Mr. and Mrs. Hollenbeck, I bade them adieu, and settled myself into the small space in the canoe that I expected to occupy for six days. Captain Anderson took the helm, the "Caribs" dipped their paddles into the water, and away we glided into a narrow channel amongst long grass and rushes that almost touched us on either side. Greytown, with its neat white houses, and feathery palms, and large-leaved bread-fruit-trees, was soon shut out from our view, and our boatmen plying their paddles with the greatest dexterity and force, made the canoe shoot along through the still water. Soon we emerged into a wider channel where a stronger stream was running, and now we coasted along close to the shore to avoid the strength of the current. The banks at first were low and marshy and intersected by numerous channels; the principal tree was a long, coarseleaved palm, and there were great beds of wild cane and grass, amongst which we occasionally saw curious green lizards, with leaf-like expansions, which like those on the leaf-insects assimilated them in appearance to the vegetation amongst which it sought its prey. As we proceeded up the river, the banks gradually became higher and drier, and we passed some small plantations of bananas and plantains made in clearings in the

forest, which now consisted of a great variety of dicotyledonous trees with many tall, graceful palms; the undergrowth being ferns, small palms, Melastomse, Heliconiae, &c. The houses at the plantations were mostly miserable thatched huts with scarcely any furniture, the owners passing most of their time swinging in dirty hammocks, and occasionally taking down a canoeload of plantains to Greytown for sale. It is one of the rarest sights to see any of these squatters at work. Their plantain patch and occasionally some fish from the river suffice to keep them alive and indolent.
At seven o'clock we reached the Colorado branch, which carries off the greater part of the waters of the San Juan to the sea. This is about twenty miles above Greytown, but only eighteen by the Colorado to the sea, and is near the head of the delta, as I have already mentioned. The main body of water formerly flowed down past Greytown, and kept the harbour there open,, but a few years ago, during a heavy flood, the river greatly enlarged and deepened the entrance to the Colorado Channel, and since then year by year the Greytown harbour has been silting up. Now, (I am writing in 1873) there is twelve feet of water on the bar at the Colorado in the height of the dry season, whilst at Greytown the outlet of the river is sometimes closed altogether. The merchants at Greytown have entertained the project of dredging out the channel again, but now that the river has found a nearer way to the sea by the Colorado this would be a herculean task, and it would cost much less money to move the whole town to the Colorado, and then by dredging the bar there a fine harbour might easily be made, but unfortunately
