"Yes, and very venomous snakes," replied Mr. Seagrave; "so that these birds are very useful in destroying them. You observe, William, that the Almighty, in his wisdom, has so arranged it that no animal (especially of a noxious kind) shall be multiplied to excess, but kept under by being preyed upon by some other; indeed, wherever in any country an animal exists in any quantity, there is generally found another animal which destroys it. The Secretary inhabits this country where snakes exist in numbers, that it may destroy them: in England the bird would be of little value."
"But some animals are too large or too fierce to be destroyed by others, papa; for instance, the elephant and the lion."
"Very true; but these larger animals do not breed so fast, and therefore their numbers do not increase so rapidly. For instance, a pair of elephants will not have more than one young one in the space of two years or more; while the rabbits, which are preyed upon and the food of so many other beasts as well as birds, would increase enormously, if they were not destroyed. Examine through the whole of creation, and you will find that there is an unerring hand, which invariably preserves the balance exact; and that there are no more mouths than for which food is provided, although accidental circumstances may for a time occasion a slight alteration."
They continued their walk until they came to the den of the lions. It was a large place, in closed with a strong and high wall of stone, with only one window to it for the visitors to look at them, as it was open above. This window was wide, and with strong iron bars running from the top to the bottom; but the width between the bars was such that a lion could put his paw out with ease; and they were therefore cautioned not to go too near. It was a fine sight to see eight or ten of these noble-looking animals lying down in various attitudes, quite indifferent apparently to the people outside--basking in the sun, and slowly moving their tufted tails to and fro. William examined them at a respectful distance from the bars; and so did Tommy, who had his mouth open with astonishment, in which there was at first not a little fear mixed, but he soon got bolder. The gentleman who had accompanied them, and who had been long at the Cape, was relating to Mr. Seagrave and Captain Osborn some very curious anecdotes about the lion. William and they were so interested, that they did not perceive that Tommy had slipped back to the grated window of the den. Tommy looked at the lions, and then he wanted to make them move about: there was one fine full-grown young lion, about three years old, who was lying down nearest to the window; and Tommy took up a stone and threw it at him: the lion appeared not to notice it, for he did not move, although he fixed his eyes upon Tommy; so Tommy became more brave, and threw another, and then another, approaching each time nearer to the bars of the window.
All of a sudden the lion gave a tremendous roar, and sprang at Tommy, bounding against the iron bars of the cage with such force that, had they not been very strong, it must have broken them. As it was, they shook and rattled so that pieces of mortar fell from the stones. Tommy shrieked; and, fortunately for himself, fell back and tumbled head over heels, or the lion's paws would have reached him. Captain Osborn and Mr. Seagrave ran up to Tommy, and picked him up: he roared with fright as soon as he could fetch his breath, while the lion stood at the bars, lashing his tail, snarling, and showing his enormous fangs.
"Take me away--take me on board the ship!" cried Tommy, who was terribly frightened.
"What did you do, Tommy?" said Captain Osborn.
"I won't throw any more stones, Mr. Lion; I won't indeed!" cried Tommy, looking terrified towards the animal.
Mr. Seagrave scolded Tommy well for his foolish conduct, and by degrees he became more composed; but he did not recover himself until they had walked some distance away from the lion's den.
They then looked at the other animals which were to be seen, Tommy keeping a most respectful distance from every one of them. He wouldn't even go near to a Cape sheep with a broad tail.
When they had seen everything, they went back to the gentleman's house to dinner; and, after dinner, they returned on board.
