"You are all right," Jim Sankey put in. "Bob's only joking."

"Well, he might as well joke with somebody else, Jim. I don't see any joke in it."

"No, that is where the joke is, Billy," Bob said. "If you did see the joke, there wouldn't be any joke in it.

"Well, never mind, here is the walnut tree. Now, who will get over first?"

The walnut tree stood in the playground near the wall, and had often proved useful as a ladder to boys at Tulloch's. One of its branches extended over the wall and, from this, it was easy to drop down beyond it. The return was more difficult, and was only to be accomplished by means of an old ivy, which grew against the wall at some distance off. By its aid the wall could be scaled without much difficulty, and there was then the choice of dropping twelve feet into the playground, or of walking on the top of the wall until the walnut tree was reached.

Tulloch's stood some little distance along the Lower Richmond Road. There were but one or two houses, standing back from the road between it and the main road up the hill, and there was little fear of anyone being abroad at that time in the morning. There was, as yet, but a faint gleam of daylight in the sky; and it was dark in the road up the hill, as the trees growing in the grounds of the houses, on either side, stretched far over it.

"I say," Jim Sankey said, "won't it be a go, if Johnny Gibson isn't there, after all?"

"He will be up there by four," Bob said, confidently. "He said his father would be going out in his boat to fish, as soon as it began to be daylight--because the tide served at that hour--and that he would start, as soon as his father shoved off the boat.

"My eye, Jim, what is that ahead of us? It looks to me like a coach."

"It is a coach, or a carriage, or something of that sort."
