“You are about right there, sir. I aint afraid of Malays, but it gives me the creeps down my back when I think of one of them chaps getting hold of me by the leg. Bob Pearson told me that the only chance you have is to send your knife, or if you can't get at that, your thumbs, into the creature's eyes. But it would require a mighty cool hand to find the eyes, with the brute's teeth in one's leg, and the water so thick with mud that you could not see an inch beyond your nose.”

“Well, I will make a note of that, anyhow, Davis, and I will take a good look at the next alligator I see dead, so as to know exactly where to feel for its eyes.”

On the second day the scenery changed. In place of the mangroves a dense forest lined the river. Birds of lovely plumage occasionally flew across it, and after they had anchored in the evening, the air became full of strange noises; great beasts rose and snorted near the banks; sounds of roaring and growling were heard in the wood; and the lads, who had been so eager before to take part in a hunt on shore, listened with something like awe to the various strange and often mysterious noises.

“What in the world does it all mean, Doctor?” Dick Balderson asked, as the surgeon came up to the spot where the four midshipmen were leaning on the rail.

“It means that there is a good deal of life in the woods. That splashing sound you hear with deep grunts and snorts, is probably made by a hippopotamus wallowing in shallow water; but it may be a rhinoceros, or even a buffalo. That roar is either a tiger or a panther, and that snarling sound on the other bank is, no doubt, made by smaller animals of the same family, indulging in a domestic quarrel. Some of the other sounds are made by night birds of some kind or other and perhaps by monkeys, and I fancy that distant vibrating sound that goes on without intermission is a concert of a party of frogs.”

“What is that?” as a shrill cry, as from a child, followed by a confused outburst of cries, chattering, and, as it seemed to them, a barking sound, followed.

“I fancy that is the death cry of a monkey. Probably some python or other snake has seized it in its sleep; and the other noise is the outcry of its companions heaping abuse upon the snake, but unable to do anything to rescue their friend.”

“I don't think, Doctor,” Harry Parkhurst said, in a tone that was half in earnest, “that I feel so anxious as I did for sport in the forest; and certainly I should decline to take part in it after nightfall.”

“I can quite understand that, lad. At night all the sounds of a tropical forest seem mysterious and weird, but in the broad daylight the bush will be comparatively still. The nocturnal animals will slink away to their lairs, and there will seem nothing strange to you in the songs and calls of the birds. I should recommend you all to take a sound dose of quinine tonight; I have a two and a half gallon keg of the stuff mixed, and any officer or man can go and take a glass whenever he feels he wants it. It would be good for your nerves, as well as neutralize the effect of the damp rising from the river. I should advise you who are not on the watch to turn in early; it is of no use your exposing yourselves more than is necessary to the miasma.”

The next day progress was more rapid, for the captain found that the assurance of the pilot that there was amply sufficient water for the Serpent had been verified, and he therefore steamed forward at half speed, without sending the launch on ahead to take soundings. Several villages were passed by the way, but though the inhabitants assembled on the banks and watched the steamer, no boats were put out, nor were any attempts made to barter their products with the strangers.
