"Possibly four weeks. Not longer."

"Call it three weeks—three weeks from to-day. That will make it the twenty-fifth. We will try to be in the vicinity of Hall's Corners on that date, and if you are not there we will wait for you. You will do the same provided we are late in reaching the Corners. Let's have a look at the contour map," suggested Grace.

While the others of the party were busy setting the camp to rights, Washington having removed the packs from the mules, Grace and Tom pored over the map of the eastern section of the mountains. Not only were they planning their routes, but they were critically examining a portion of the map that was encircled with a ring of red ink. The space within the circle represented a tract of mountain land that belonged to Lieutenant Hippy Wingate, property that he had inherited.

Hippy had never seen this property, it having been left to him by a wealthy uncle whose large fortune Hippy had inherited while fighting the Germans in the air in France. He now proposed to look it over. In fact, this journey of the Overland Riders had been planned with that object in view.

Following their return from France, where they had served in the Overton College Unit, Grace having been an ambulance driver at the front, the girls had decided to seek recreation in the saddle each summer. Their first vacation was spent in an exciting ride over the Old Apache Trail in Arizona, following this with a venturesome journey on horseback across the arid waste of the Great American Desert. Lieutenant Wingate's determination to visit his property in the Kentucky Mountains led the Overland Riders, as Grace Harlowe and her friends called themselves, to make those mountains the objective of their third vacation in the saddle.

After Tom Gray had finished his government survey, it was their purpose to proceed with him to Lieutenant Wingate's tract, where Tom was to make a survey and examination of it, so that Hippy might learn whether or not the property possessed any particular value.

"Hippy says his uncle took the property in payment of a debt, but that the uncle never had considered it to be worth much of anything," said Tom reflectively. "From what little I know of that section of the country, I am inclined to agree with him. However, we shall see when we get there."

"Who knows but that Hippy may find still another fortune awaiting him there?" suggested Grace.

Tom shook his head and smiled.

"It would be Hippy's luck, wouldn't it? He doesn't need it; he already has more money than he knows what to do with. Nor have I the slightest hope that he will find anything of value there. The twenty-fifth, then, it is. I shall make Chapman's my base and work from there. If necessary to communicate with me in the meantime you may address me there. I—"
