One of the boys' occasional pastimes was to climb Holliday's Hill and roll down big stones, to frighten the people who were driving by. Holliday's Hill above the road was steep; a stone once started would go plunging downward and bound across the road with the deadly momentum of a shell. The boys would get a stone poised, then wait until they saw a team approaching, and, calculating the distance, would give the boulder a start. Dropping behind the bushes, they would watch the sudden effect upon the party below as the great missile shot across the road a few yards before them. This was huge sport, but they carried it too far. For at last they planned a grand climax that would surpass anything before attempted in the stone-rolling line. A monstrous boulder was lying up there in the right position to go down-hill, once started. It would be a glorious thing to see that great stone go smashing down a hundred yards or so in front of some peaceful-minded countryman jogging along the road. Quarrymen had been getting out rock not far away and had left their picks and shovels handy. The boys borrowed the tools and went to work to undermine the big stone. They worked at it several hours. If their parents had asked them to work like that, they would have thought they were being killed. Finally, while they were still digging, the big stone suddenly got loose and started down. They were not ready for it at all. Nobody was coming but an old colored man in a cart; their splendid stone was going to be wasted. One could hardly call it wasted, however; they had planned for a thrilling result, and there was certainly thrill enough while it lasted. In the first place the stone nearly caught Will Bowen when it started. John Briggs had that moment quit digging and handed Will the pick. Will was about to take his turn when Sam Clemens leaped aside with a yell: "Lookout, boys; she's coming!" She came. The huge boulder kept to the ground at first, then, gathering momentum, it went bounding into the air. About half-way down the hill it struck a sapling and cut it clean off. This turned its course a little, and the negro in the cart, hearing the noise and seeing the great mass come crashing in his direction, made a wild effort to whip up his mule. The boys watched their bomb with growing interest. It was headed straight for the negro, also for a cooper-shop across the road. It made longer leaps with every bound, and, wherever it struck, fragments and dust would fly. The shop happened to be empty, but the rest of the catastrophe would call for close investigation. They wanted to fly, but they could not move until they saw the rock land. It was making mighty leaps now, and the terrified negro had managed to get exactly in its path. The boys stood holding their breath, their mouths open.
