They walked possibly a quarter of a mile till they reached a comparatively open space near the center of which stood a tall tree.
"We will stop here," said Anthony.
Mark lowered the spade, which he had been carrying on his shoulder, and waited further instructions.
Old Anthony produced a compass to make sure of his bearings, and a tape measure. One end of this he gave to Mark, saying: "Stand by the tree."
Mark, wondering as much as ever, took his position beside the tree.
"A little more on that side!" was the next direction.
When Mark was placed to suit him, Anthony took the other end of the tape measure, and measured due east sixteen feet.
"Yes," he said musingly, "this must be the spot."
Marking the spot with a stone, he said:
"Bring the spade to me, Mark."
