“Shall we have an afternoon off, Jervis?” he said gaily. “It is a fine day and work is slack just now. What say you to the Zoo? They have a splendid chimpanzee and several specimens of that remarkable fish Periophthalmos Kölreuteri. Shall we go?”

“By all means,” I replied; “and we will mount the elephant, if you like, and throw buns to the grizzly bear and generally renew our youth like the eagle.”

But when, an hour later, we found ourselves in the gardens, I began to suspect my friend of some ulterior purpose in this holiday jaunt; for it was not the chimpanzee or even the wonderful fish that attracted his attention. On the contrary, he hung about the vicinity of the lamas and camels in a way that I could not fail to notice; and even there it appeared to be the sheds and houses rather than the animals themselves that interested him.

“Behold, Jervis,” he said presently, as a saddled camel of seedy aspect was led towards its house, “behold the ship of the desert, with raised saloon-deck amidships, fitted internally with watertight compartments and displaying the effects of rheumatoid arthritis in his starboard hip-joint. Let us go and examine him before he hauls into dock.” We took a cross-path to intercept the camel on its way to its residence, and Thorndyke moralized as we went.

“It is interesting,” he remarked, “to note the way in which these specialized animals, such as the horse, the reindeer and the camel, have been appropriated by man, and their special character made to subserve human needs. Think, for instance, of the part the camel has played in history, in ancient commerce—and modern too, for that matter—and in the diffusion of culture; and of the rôle he has enacted in war and conquest from the Egyptian campaign of Cambyses down to that of Kitchener. Yes, the camel is a very remarkable animal, though it must be admitted that this particular specimen is a scurvy-looking beast.”

The camel seemed to be sensible of these disparaging remarks, for as it approached it saluted Thorndyke with a supercilious grin and then turned away its head.

“Your charge is not as young as he used to be,” Thorndyke observed to the man who was leading the animal.

“No, sir, he isn’t; he’s getting old, and that’s the fact. He shows it too.”

“I suppose,” said Thorndyke, strolling towards the house by the man’s side, “these beasts require a deal of attention?”

“You’re right, sir; and nasty-tempered brutes they are.”
