write about a incidence where a boat was tored by a boy riding on a horse??? (chapter 9)

"Another example of the dangerous want of sympathy between tower and towed was witnessed by George and myself once up near Walton. It was where the tow-path shelves gently down into the water, and we were camping on the opposite bank, noticing things in general. By-and-by a small boat came in sight, towed through the water at a tremendous pace by a powerful barge horse, on which sat a very small boy. Scattered about the boat, in dreamy and reposeful attitudes, lay five fellows, the man who was steering having a particularly restful appearance." (ch. 9)
