It was when the round-up was on its way in that Billy, stopping for an hour in Hardup, met Dill in the post office.
"Why, hello, Dilly!" he cried, really glad to see the tall, lank form come shambling in at the door. "I didn't expect to see yuh off your own ranch. Anybody dead?" It struck him that Dill looked a shade more melancholy than was usual, even for him.
"Why, no, William. Every one is well--very well indeed. I only rode in after the mail and a few other things. I'm always anxious for my papers and magazines, you know. If you will wait for half an hour--you are going home, I take it?"
"That's where I'm sure headed, and we can ride out together, easy as not. We're through for a couple uh weeks or so, and I'm hazing the boys home to bust a few hosses before we strike out again. I guess I'll just keep the camp running down by the creek. Going to be in town long enough for me to play a game uh pool?"
"I was going right out again, but there's no particular hurry," said Dill, looking over his letters. "Were you going to play with some one in particular?"
"No--just the first gazabo I could rope and lead up to the table," Billy told him, sliding off the counter where he had been perched.
"I wouldn't mind a game myself," Dill observed, in his hesitating way.
In the end, however, they gave up the idea and started for home; because two men were already playing at the only table in Hardup, and they were in no mind to wait indefinitely.
Outside the town, Dill turned gravely to the other, "Did you say you were intending to camp down by the creek, William?" he asked slowly.
"Why, yes. Anything against it?" Billy's eyes opened a bit wider that Dill should question so trivial a thing.
"Oh, no--nothing at all." Dill cleared his throat raspingly. "Nothing at all--so long as there is any creek to camp beside."
"I reckon you've got something to back that remark. Has the creek went and run off somewhere?" Billy said, after a minute of staring.
"William, I have been feeling extremely ill at ease for the past week, and I have been very anxious for a talk with you. Eight days ago the creek suddenly ran dry--so dry that one could not fill a tin dipper except in the holes. I observed it about noon, when I led my horse down to water. I immediately saddled him and rode up the creek to discover the cause." He stopped and looked at Billy steadily.
