“Why, that’s queer!” he exclaimed. “It’s stone, as I thought, but it isn’t a rock. It’s been shaped with a chisel and it looks as though it had figures or letters on it.”

“How on earth did a thing like that get here?” asked Fred, in a puzzled tone.

“I can make out something like the letter C,” said Bobby. “C-A-R-T——why, Lee, I believe it’s your name!”

The next instant he leaped to his feet, as the full significance of his discovery flashed upon him.

“Hurrah!” he shouted. “Glory hallelujah! Lee, we’ve found one of the boundary stones of your mother’s property.”

“What?” cried Lee, all a-tremble with excitement.

“Are you sure?” queried Fred, dropping on hands and knees beside his friend.

“It sure looks like it,” affirmed Bobby, digging away like mad to uncover more of the stone.

The others followed his example and made the dirt fly, for all the world, as Fred said afterward, “like dogs digging out a woodchuck.”
