Read it through once

At that time it was customary to carry Convicts down to the dock-yards by stage-coach. As I had often heard of them in the capacity of outside passengers, and had more than once seen them on the high road dangling their ironed legs over the coach roof, I had no cause to be surprised when Herbert, meeting me in the yard, came up and told me there were two convicts going down with me. But I had a reason that was an old reason now for constitutionally faltering whenever I heard the word “convict.”
