"What the deuce is the matter with the dog?" growled Holmes. "They surely would not take a cab, or go off in a balloon."
"Perhaps they stood here for some time," I suggested.
"Ah! it's all right. He's off again," said my companion, in a tone of relief.
He was indeed off, for after sniffing round again he suddenly made up his mind, and darted away with an energy and determination such as he had not yet shown. The scent appeared to be much hotter than before, for he had not even to put his nose on the ground, but tugged at his leash and tried to break into a run. I cold see by the gleam in Holmes's eyes that he thought we were nearing the end of our journey.
Our course now ran down Nine Elms until we came to Broderick and Nelson's large timber-yard, just past the White Eagle tavern. Here the dog, frantic with excitement, turned down through the side-gate into the enclosure, where the sawyers were already at work. On the dog raced through sawdust and shavings, down an alley, round a passage, between two wood-piles, and finally, with a triumphant yelp, sprang upon a large barrel which still stood upon the hand-trolley on which it had been brought. With lolling tongue and blinking eyes, Toby stood upon the cask, looking from one to the other of us for some sign of appreciation. The staves of the barrel and the wheels of the trolley were smeared with a dark liquid, and the whole air was heavy with the smell of creasote.
Sherlock Holmes and I looked blankly at each other, and then burst simultaneously into an uncontrollable fit of laughter.
