There were caverns in Formosa, and they were walking along, exploring some, Leonard some little way in front of Mr. Graham, the teacher, and a native guide, who followed a few yards behind, when the English boy suddenly caught sight of two huge, yellow serpents twined round the branch of an overhanging tree. No one but Leonard was near enough to see them, and as the first creature stretched its dreadful-looking head out, hissing towards him, the brave, self-possessed little fellow, who held a stick in his hand, struck his deadly foe with it with all his might, and hit and aimed so well that he had the satisfaction, the next moment, of seeing the serpent roll over and over down the rock. But then the further one (which, although rather smaller than the other, measured about six feet) wound, in a moment, its wriggling body round the branch of the tree, stretching its head out almost within reach of Leonard, when the boy-guide and Mr. Graham, the same instant, came upon the spot. The boy, accustomed to such encounters, at once dealt the snake a blow, that caused it to lose its balance, and thus all were able to pass on their way in thankfulness and safety.

When Sybil heard of the adventure she was very proud of her little brother; but, as he had imagined when she heard that Formosa was inhabited by serpents, she was glad also to think that it was settled for them to leave that island for Swatow in two days' time.

PEPOHOANS AND THEIR HUT.

That evening was spent very pleasantly comparing notes of adventure with an English gentleman, who had been in Formosa for some time, and now called upon Mr. Graham and his family, who were staying at the consul's. He had seen and done a good deal, he said, but he spoke very highly of Leonard's brave exploit.

HUT OF ONE OF THE SAVAGE TRIBES.

In the course of his wanderings, he told them, he had visited the village of Lalung, which is situated on the narrowest part of a large river. During the rainy season the waters would here rise and cover a vast bed, opening out a new passage across the land, and flowing away towards the eastern plain. Great mountain heights surrounded the bed of the river, and the violence of the torrent carried away very large quantities of all sorts of rubbish, which the sea would collect, and deposit, along the eastern coast. Mr. Hardy explained to Leonard how this would account for the port of Thaï-ouan disappearing, and that of Takow forming lower down.
