"Maybe Harry fell in that river and was drowned," suggested Tubby, pointing ahead down the tracks to the trestle crossing the San Pedro River. At this time of the year the so-called river was a mere trickle of mud-colored water, threading its way between high, sandy banks. The boys burst into a laugh at the idea of any one's drowning in it.

"He'll be here before long," said Rob confidently. "It's a drive of more than fifty miles to the ranch, remember, and we can't start out till to-morrow morning, anyhow."

Just then a white-aproned Chinaman appeared on the porch of the hotel and vigorously rang a bell. At the signal the lounging cow-punchers and plainsmen rose languidly from their chairs and bolted into the dining-room. From the few stores also appeared the merchants of Mesaville, most of whom lived at the hotel.

"Sounds like dinner," remarked Tubby hopefully, sniffing the air on which an odor of food was wafted across the tracks. "Smells like it, too."

"Trust Tubby to detect grub," laughed Rob.

"He's a culinary Sherlock Holmes," declared Merritt, but his remark was made to Rob alone, for Tubby was beyond the reach of his sarcasm. He had started at once to cross the tracks and find the dining-room.

"I guess it wouldn't be a bad idea to have something to eat while we're waiting," said Rob. "Let's go over."

Tubby was already installed in a seat at the long table when his chums entered. He had in front of him a plate of soup, on the top of which floated a sort of upper crust of grease. From time to time an investigating fly ventured too near the edge and was miserably drowned. It was Tubby's initiation into desert hotel life, and he didn't look as if he was enjoying it.

On both sides of the table, however, the cow-punchers, teamsters, and Mesaville commercial lights, were shoveling away their food without the flicker of an eyelash. Opposite to Tubby were seated two young fellows in cowboy garb, who seemed to extract much noisy amusement from watching the stout youth eat. They didn't seem to care if he overheard their somewhat personal remarks.

"Ah, there's a lad who'll be a help to his folks when he grows up," grinned one of the stout boy's tormentors, as Rob and Merritt took their seats.
