"She tried to find out all she could," said Mollie when the outdoor girls had gotten out of sight in the woods. "That's all she talked for."

"Yes, and I believe they just came up here camping because they heard we were here," went on Betty. "Oh, I do hope we don't get into any trouble with them."

"It will have to be of their making," said Grace firmly. "I'll never set foot on that land Mr. Jallow claims if I can help it. It might complicate legal matters."

"That is a wise decision," said Allen, viewing it from a lawyer's standpoint. "Let the trespass come from them, if there is to be any."

They talked over the unexpected meeting with their rivals, and speculated as to when they had come, and the motive that brought them, also, to a winter camp.

"I believe it's just to spy on us!" declared Mollie. "We have evidently frightened them, Grace."

"Then they must have something to be frightened about," said Will. "I do wish we could get on the track of something, or somebody, who could let us know how to prove that the boundary is wrong; for wrong father surely thinks it is."

"We'll do the best we can," suggested Allen. "I am going to send for copies of the deeds, and then we'll look along the present boundary marks. I may be able to see if they have been changed. I once studied surveying."

"I want you boys to promise something," said Grace, as they neared their cabin.

"What is it?" asked Frank.
