Hi Lang's face showed his interest. He asked questions and frowned thoughtfully, requesting that they point out as closely as possible the spot at which the man had been seen.

"You say he disappeared suddenly?"

"Yes, Mr. Lang," answered Grace.

"Was that when I was coming up?"

"You were."

"He evidently saw me and ducked. There's a high ridge of sand over there where you saw him. He was on that ridge or you wouldn't have seen him, and when he discovered me he just naturally slid his pony down the other side and walked away under cover of the ridge or else got down and peeked over the top of it. I don't like that. You weren't thinking of going on to-night, were you?"

"Not unless you think best, Mr. Lang," replied Grace.

"Then I reckon I'll ride over there in the morning and see what his tracks look like. To-morrow night we'll make camp by the water hole I found to-day, unless some other party comes along and dips the water all out or it disappears between now and then."

"Did you answer our signal shots that you say you thought you heard?" asked Hippy.

"Of course I did, though I didn't think you would hear them, being as there was a gentle breeze from this direction against me. I staked the ponies down before I went away this morning, and that black bronco of yours gave me some trouble, Mrs. Gray. I had to lasso him. When are you going to learn to throw the rope?"
