When I came to his cage, I didn't see anything but the branch of a tree, such as I had seen in other cages, for the snakes to wind up and down. 'Where is he, I wonder? I hope he hasn't got out,' I said to myself, thinking of a story I read once of a person in a menagerie, who turned suddenly and saw a great boa gliding towards him. As I stood wondering if the big worm could be under the little flat blanket before me, the branch began to move all at once, and with a start, I saw a limb swing down to stare at me with the boa's glittering eyes. He was so exactly the colour of the bare bough, and lay so still, I had not seen him till he came to take a look at me. A very villainous-looking reptile he was, and I felt grateful that I didn't live in a country where such unpleasant neighbours might pop in upon you unexpectedly. He was kind enough to take a promenade and show me his size, which seemed immense, as he stretched himself, and then knotted his rough grayish body into a great loop, with the fiery-eyed head in the middle. He was not one of the largest kind, but I was quite satisfied, and left him to his dinner of rabbits, which I hadn't the heart to stay and see him devour alive. I was walking toward the camel's pagoda, when, all of a sudden, a long, dark, curling thing came over my shoulder, and I felt warm breath in my face. 'It's the boa;' I thought, and gave a skip which carried me into the hedge, where I stuck, much to the amusement of some children riding on the elephant whose trunk had frightened me. He had politely tried to tell me to clear the way, which I certainly had done with all speed. Picking myself out of the hedge I walked beside him, examining his clumsy feet and peering up at his small, intelligent eye. I'm very sure he winked at me, as if enjoying the joke, and kept poking his trunk into my pocket, hoping to find something eatable. I felt as if I had got into a foreign country as I looked about me and saw elephants and camels walking among the trees; flocks of snow-white cranes stalking over the grass, on their long scarlet legs; striped Zebras racing in their paddock; queer kangaroos hopping about, with little ones in their pouches; pretty antelopes chasing one another; and, in an immense wire-covered aviary, all sorts of brilliant birds were flying about as gaily as if at home. One of the curiosities was a sea-cow, who lived in a tank of salt water, and came at the keeper's call to kiss him, and flounder on its flippers along the margin of the tank after a fish. It was very like a seal, only much larger, and had four fins instead of two. Its eyes were lovely, so dark and soft and liquid; but its mouth was not pretty, and I declined one of the damp kisses which it was ready to dispense at word of command.
