Casey Dunne, busily engaged in strengthening a working harness with rivets, looked up as a shadow fell across the morning sunlight. The shadow belonged to Tom McHale.

McHale, like Dunne himself, had seen rough times. Older than his employer, he had wandered up and down the West in the good old days of cheap land and no barbed wire, engaged in the congenial, youthful occupation of seeing as much country as he could. In the process, he had turned his hand to almost everything which had fresh air as a collateral, from riding for a cattle outfit to killing meat for railway camps. He and Dunne had come into the Coldstream country at nearly the same time; but Dunne had some money and McHale none at all. Dunne bought land and hired McHale. They worked side by side to make the ranch. McHale bought forty acres from Dunne and worked out the price, bought more, and was still working it out. But apart from financial matters they were fast friends, and either would have trusted the other with anything he possessed.

"Say," said McHale, "there's something wrong. Our ditches ain't runnin'

more'n half full."

Casey put down the hammer. "Maybe the ditch is plugged somewhere."

"She may be, but it ain't likely. I've followed her quite a piece. So I come to get me a cayuse to go the rest of the way."

"I'll go with you," said Casey, throwing the harness on a peg.

In five minutes they were loping easily along the ditch, with sharp eyes for possible obstructions. As McHale had said, it was running not half full, and seemed to be falling. The strong, deep, gurgling note of a full head of water was gone. Instead was a mere babble.

So far as they could see, the flow was unhindered by obstacles; there was no break in the banks. Even around the treacherous sidehill there was no more than the usual seepage. And so at last they rode down to the Coldstream itself, to the intake of the ditch, a rude wing dam of logs, brush, and sand bags, which, nevertheless, had served them excellently heretofore.

"I'm an Injun," McHale, e.j.a.c.u.l.a.t.ed, "if the whole durn creek ain't lowered!" Because he came from a land of real rivers, he invariably referred to the Coldstream thus slightingly.

But unmistakably it had fallen. Half the dam appeared above the surface, slimy, weed-grown, darkly water-soaked. Naturally, with the falling of the water, the ditch had partially failed.

The two men looked at each other. The same thought was present in the mind of each. It was barely possible that a land or rock slide somewhere high upstream had dammed or diverted the current; but it was most improbable. The cause was nearer to seek, the agency extremely human.

McHale bit into fresh consolation and spat in the direction of the inadequate dam.

"I reckon they've started in on us," he observed.

"Looks like it," Casey agreed.

"We need water now the worst way. I was figurin' on shootin' a big head on to the clover, and after that on to the oats. They sure need it.

What's runnin' now ain't no use to us. We got to have more."

"No doubt about that, Tom," said Casey. "We'll ride up to their infernal dam and see just what's doing."

"Good enough!" cried McHale, his eyes lighting up. "But say, Casey, them ditch-and-dam boys ain't no meek-and-lowly outfit. Some of 'em is plumb hard-faced. How'd it be if I scattered back to the ranch first. I ain't packed a gun steady since I got to be a hayseed, but----"

"What do you want of a gun? We're just going to look at things and have a talk with Farwell."

"You never know when you'll need a gun," McHale a.s.serted, as an incontrovertible general proposition.

"You won't need it this time. Come along."

It was almost midday when they came in sight of the construction camp beside the dam. To their surprise, a barbed wire fence had been thrown around it, enclosing an area of some twenty acres. On the trail, a s.p.a.ce had been left for a gate, but it had not yet been hung. Beside it stood a post bearing a notice board, and, sitting with his back against the post, a man rested, smoking. As they came up, he rose and sauntered into the trail between the gate-posts.

"Hey you, hold on there!" he said.

Dunne and McHale pulled up.

"Look a-here, friend," said the latter, "do you think you're one of them never-sag gates, or a mountain, or what? You want to see a doctor about them delusions. They'll sure get you into trouble some day."

"That'll be all right about me," the big guardian of the gate returned.

"Just read that notice. This is private property."

They read it. It was of the "no-admittance" variety, and forbade entrance to all individuals not in the company's employ.

"We've got business here, and we're going in," said Casey, and began to walk his horse forward.

The man caught the bridle with one hand. The other he thrust into his pocket.

"You get back now," he ordered, "or you'll walk home."

Dunne stopped instantly. His companion's hand made one lightninglike motion, and perforce came up empty.

"And this," said Mr. McHale mournfully--"this was the time I didn't need a gun!"

"Well, you don't need it, do you?" said Casey. "Observe, the gentleman still keeps his sawed-off yeggman's delight in his pocket. Pull it, friend, pull it! Don't scorch the cloth by pressing the trigger where it is. Steady, Shiner, while the gentleman shoots you!"

The guardian smiled sardonically. "Amuse yourselves, boys, but don't crowd in on me."

"Just as you say," replied Casey. "By the way, you needn't tire your arm holding my horse. He'll stand. Besides, I don't like it."

The man released the bridle and stepped back. "Make this easy for me, boys, I don't want trouble, but I got my instructions."

"Now, you listen here," said McHale. "Lemme tell you something: It's just h.e.l.l's tender mercy on you I ain't got a gun. If I'd 'a' had it, you'd been beef by the trail right now."

"There's always two chances to be the beef," the other returned, unmoved. "Go fill your hand before you talk to me."

McHale grinned at him. "I like you better than I did, partner. Next time you won't have no kick on what I hold."

"We want to see Farwell," said Casey.

"Why couldn't you say that before?" the guardian returned. "I'll take a chance on you. Go in."

They found Farwell at his quarters before a table covered with prints and tracings.

"What can I do for you?" he asked curtly.

"My ditch has gone half dry," Casey replied. "I observe, too, that the river is lower than usual; which, of course, accounts for the ditch. It occurred to me that perhaps you might account for the river."

"We have begun to take water for our lands," Farwell told him.

"Possibly that has something to do with it."

"I shouldn't wonder," Casey agreed dryly. "Why are you taking water now?"

"That," said Farwell deliberately, "is entirely our own affair."

"It affects us. You can't possibly use the water, because your lands are not cultivated."

"The water benefits the land," Farwell rejoined coldly. "It shows intending purchasers that we are actually delivering a sufficient quant.i.ty of water. Our use of it is legitimate."
