"No," answered the senator's son. "We've been wondering if they had anything to do with the disappearance of the horses."

"We have been wondering the same thing," said Phil.

"I spoke to papa about it, and he says he will interview Mr. Merwell—if they get no trace of the thieves," said the ranch owner's daughter.

Those who had been at the shack all night were so tired that they went to bed directly after eating, and Dave and Phil were glad enough to rest some more; so that the balance of the day passed quietly. It was not until after sundown that Mr. Endicott showed himself, followed by about half of the ranch hands.

"We thought we found the trail, but we lost it again," said the ranch owner. "Todd and some of the others are still at it, but I am afraid the thieves are out of our reach. I have sent word to the sheriff, and I suppose he'll put some men on the trail to-morrow."

"Did you stop at the Merwell ranch?" asked Belle.

"Yes, I stopped there less than an hour ago. Mr. Merwell had just come in from a hunt for Link."

"What! then Link isn't back yet?" cried Dave.

"No, and his father was a good deal worried about his absence. When I told about the loss of the horses, Mr. Merwell was worried more yet. He said we needn't think that his son touched them."

"It is queer where Link is keeping himself," mused Roger.
