There was no difficulty about this. On leading Toby to the place where he had committed his fault, he cast about in a wide circle and finally dashed off in a fresh direction.

“We must take care that he does not now bring us to the place where the creosote-barrel came from,” I observed.

“I had thought of that. But you notice that he keeps on the pavement, whereas the barrel passed down the roadway. No, we are on the true scent now.”

It tended down towards the riverside, running through Belmont Place and Prince’s Street. At the end of Broad Street it ran right down to the water’s edge, where there was a small wooden wharf. Toby led us to the very edge of this, and there stood whining, looking out on the dark current beyond.
