Tom and Desmond considered it advisable on their return to move further away from the river. Fortunately they did so, for while they were sitting round the fire cooking their game, a dozen crocodiles crept out of the water and came towards them. The whole party, starting to their feet, shouted and shrieked, but not until Tom and Desmond had fired down the throats of a couple of the saurians did the rest turn tail, when, plunging into the water, they disappeared beneath the surface.

“If we don’t keep a bright look-out during the night one or other of us will be carried off, depend upon that,” observed Tom.

His warning had a good effect, and it was agreed that two of the party should keep watch together, as they had to risk an attack from crocodiles on one side and tigers on the other, not to speak of big serpents and other creatures. The most dangerous of these were scorpions, several of which were seen five and six inches long, with stings which the natives asserted would deprive a person of life in the course of an hour or less.

“Oh dear, oh dear!” sighed Billy. “I knew the journey would be fatiguing enough, but I little thought the trouble all these horrid beasts would cause us.”

For several days they travelled on along the course of the river, but taking care not to camp near enough to the bank to be surprised by a hungry crocodile. On several occasions they caught sight of tigers, and three were shot which came nearer to them than was pleasant. Among the vast numbers of the feathered tribe which perched in the trees, or flitted amid the boughs, or soared high into the air, were the beautiful birds of paradise, of brilliant colours and graceful forms, which Tom and Desmond agreed it was a shame to kill when they could obtain as much game of a different species as they required. Monkeys of various sizes were seen, some not larger than cats and others half as big as a man. The travellers were moving on, Nick and Pipes scouting in front, the three midshipmen following, Casey and the black bringing up the rear. Presently they heard a loud chattering overhead, and down came a shower of nuts, one of which hit Billy on the nose. The pain made him cry out, when his voice was replied to by shrieks of laughter from overhead, followed by another volley. On looking up they caught sight of a large troop of big monkeys scampering from bough to bough, some of them descending as close as possible in order to get nearer the intruders of their domain.

One old fellow spat right at Desmond, and when he saw that the shot had been successful, shrieked and chuckled with laughter as he climbed back to a more secure part of the bough. The monkeys on this, emboldened by success and increased in numbers, discharged volleys of missiles of all descriptions, some of a very disagreeable character, so that the three midshipmen with their followers were fairly put to flight, the monkeys pursuing them, chattering and shrieking until they made their escape from the forest, which here fortunately came to a termination.

“I’ll pay you off for this!” cried Desmond, who had been a sufferer with Billy, and, firing, he brought down one of the monkeys, on which the rest set up the most fearful cries, shaking their fists and making all sorts of defiant grimaces.

They now entered on a region totally different to any they had hitherto passed through. It was a vast open prairie, covered in many places with long grass, amid which snakes of large size were seen creeping, but Nick assured Tom that they were not venomous, and would afford a meal at any time, should game not be abundant. The difficulty of walking over this grass was considerable, as they had to lift their feet high at every step, while they were exposed to the rays of the sun. Having hitherto obtained as much water as they required, it did not occur to them that they might fail to procure it. They caught sight of herds of buffalo and deer, but none during the day came near enough to be shot. All day they trudged on without water, and were well nigh ready to drop from thirst.

“I shall die if I don’t get something to drink,” cried poor Billy.

Tom got Casey and Peter to lift him up on their shoulders that he might obtain thereby a wider view, but nowhere was a stream or lake to be seen. He, however, caught sight of several round yellow objects on the ground, and on getting nearer, great was the joy of the party to discover that they were melons, the produce of a creeper with ivy-shaped leaves.
