"I don't want a hydropathic exactly," I explained. "I propose to exterminate this rodent, not to foster longevity in it. How does it work?"

He pointed out that, after examining the various apartments, the animal would be allured by the fragrance of a small portion of cheese placed above the diving-board; overbalancing, it would then be projected into the water, where it would infallibly drown. "It is a thoroughly humane instrument," he assured me, "and used in the best 'omes."

I bought it and went on to a cheese foundry. Araminta was rather scornful of the sanatorium when I came home with it and set it, loaded and trained, on the dining-room floor; but the children were delighted. It ranked only a little lower than the pantomime, and if only we could have secured an outside visitor to it I believe that it would have defeated the Zoo. To visit it with a sort of wistful hope became the principal treat of the day. But, alas, the mansion remained untenanted. Sometimes during a lull in conversation we would hear the faint scuffling again, but after about six days I became convinced, by kneeling down and placing my ear to the carpet like an Indian, that the noise was even fainter than it had been at first. A terrible suspicion seized me. I dashed out and rang the bell of the flat next door.

"It is just as I feared," I said to Araminta on returning a few moments later. "We are not going to be infested after all. The vermin has been sighted in No. 140b."

"We must make the best of it," she said, trying to speak cheerfully, "though it is hard on the children, poor dears."

"I wasn't thinking of the children," I replied bitterly; "I was thinking of the expense. If we had been living in a house instead of a flat we could at least have deducted it from the rates."

I sat down and made out a bill as follows to the Clerk of the Borough Council, heading it:—

On Account of Spurious Infestment. s. d. To one Mouse Institute and Aquarium 5 6
" Cheese 0 6
" Labour at 2/6 per hour 0 71/2
------
Total 6 71/2

The man replied coldly that the householder was responsible for all expenditure incurred in precautionary measures and that the Council was in no way liable for the costs resulting from an offensive that failed to materialize. He ended with the rather rude postscript, "What kind of cheese did you use?"

This was a bit sickening. However, by threatening to lay information against him, I have at last succeeded in inducing the occupier of 140b to take over the abattoir at a very satisfactory valuation. It was between that and buying his mouse.
