So, with not a little searching of heart, I turned my attention to mad dogs. I must confess that my heart did not go out towards them, and I could have wished that that mark of heroism had been omitted by the authorities. But, on the contrary, it was insisted upon vehemently, and there was no getting out of it. So, like another Perseus, I choked down my emotion and girded myself for the new fray. I knew the authorities, as a rule, were silent as to any precautions which their heroes may have taken for this particular service. Still, as they said nothing against it, I did the best I could by means of my unaided genius. I contrived a pair of secret zinc leggings to wear under my trousers. They hurt me, it is true, and impeded my movements; still, I felt pretty safe in them. I also adopted the habit of wearing stout leather driving-gloves on every occasion, besides concealing an effective life- preserver about my person. Nothing, in short, was wanted to complete my equipment but the mad dog; and he never turned up. One day I saw by the paper that there was one at large in Hackney, and thither I repaired, in greaves and gauntlets, with my life-preserver in my bosom. But though I met many dogs, they were all of them sane. Not one of them foamed at the mouth or looked out of the corner of his eyes. There was one collie certainly who appeared to me more excited than the rest, and who by his proceedings seemed to menace the safety of a small group of children who were taking their walks abroad with their nurse. Not to be precipitate, I watched him for some time, to make quite sure I was right. Then, when one of the children uttered a scream, I felt my hour was come. So I drew my life-preserver and advanced boldly to the rescue. At the sight of me in this threatening attitude the children and nurse all set up a scream together, and the dog, showing his teeth and uttering a low growl, caught me by the fleshy part of my leg above the zinc and held me there until his little masters and mistresses, having recovered their wits and heard my scarcely articulate explanations, called him off, and allowed me to go in peace--I might almost say in pieces. I was a good deal discouraged after this unfortunate affair, and might have postponed indefinitely my further experiments, had not fortune unexpectedly placed in my way what appeared to be an opportunity of dealing with a burglar after the most approved fashion of heroism. I was on a visit to an uncle who lived in rather a grand house at Bayswater, and kept up what people are wont to call a good deal of style. This "style" always rather depressed me, for it left me no opening for distinguishing myself on the heroic side of my character, and after a week I was beginning to get home-sick, when a curious incident occurred to break the monotony of my visit.
