A few minutes of hard work, and enough of the stone was uncovered to permit them to make out the inscription. It was time-stained and weatherbeaten, but read as follows:

S.E. Limit of property of N. CARTIER, Laboulaye Parish, La.

Then followed some surveyor’s signs and symbols, which to the boys were like so much Greek. Underneath these however was an arrow pointing in a certain direction, and Bobby studied this for several minutes with great attention.

“What do you make of it?” asked Fred curiously, as he noted his friend’s puckered brow.

“This arrow means something,” replied Bobby, “and I think we’d better follow in the direction in which it points. I tell you what we do. You stand here, Fred, and Lee and I will follow the line of the arrow. If you see us getting out of line, you wave to us and set us right.”

This was agreed to, and Bobby and Lee set out. They had gone a distance of perhaps two hundred yards, when Bobby’s keen eyes saw a rim of stone just projecting above the ground. They cleared away the moss and rubbish about it and found that it was another landmark, practically the same as the first, except that in this case the arrow pointed slightly in another direction, showing that the boundary line veered at that point.

They shouted to Fred and he quickly rejoined them.

“Now,” said Bobby jubilantly, “the rest will be easy. All we’ve got to do is to report the location of these two stones and a surveying party can go from stone to stone and so trace out the whole boundary line of the property.”

“Look!” exclaimed Fred suddenly, pointing to the right.

They looked and saw a figure just vanishing behind a tree.
