But the worst of it all was that he had nothing to go on. There was not a shred of evidence to connect Dunne with the destruction of the dam and flume. The detective sent down by the company had looked wise but had found out nothing. The only thing in the nature of a clew was a moccasin track, and that led to young McCrae, whom, for Sheila's sake, he did not wish to involve. He felt that through no fault of his own he had made a mess of everything. The ranchers had won every round. As Africa had been the grave of countless military reputations, so Farwell saw his own repute interred along the Coldstream.

Something had to be done. He was tired of taking unavailing precautions, of sitting passively waiting for attacks. In the nature of things it was impossible to guard adequately works extending over miles of uninhabited country. Guerilla warfare could not be met by regular tactics.

As he scowled down at the muddy torrent an idea began to germinate in his mind. The main thing was to crush these ranchers, to bring them to their knees. After that all would be easy, there would be an end of difficulties. The engineering problems were the least. He had a free hand; he was backed by an enormous corporation which would go the limit. He resolved to fight fire with fire—to give the ranchers a dose of their own medicine.

CHAPTER XV

When Clyde Burnaby entered Wade's office, that busy lawyer was much surprised. "I thought you had gone away," he said as they shook hands. "It beats me how any young woman with the price of an elsewhere can stay in this town in summer."

Clyde laughed as she sat down. She looked deliciously cool, though the mercury was in the nineties, and the dusty cañonlike streets were like ovens. "I was on the point of going," she admitted, "but I don't know where to go. I came for some information on another point, Mr. Wade."

"Yes?" said Wade interrogatively. "We carry a very complete stock of information here." He waved a hand at the formidable rows of half-calf and circuit bindings in his bookcase. "What particular shade, model, or style may I show you? Something seasonable and yet durable? Here is a very attractive and well-bound ten-pound creation covering most of the common or garden varieties of contract, including breach of promise to marry. Nice summer reading. Or, perhaps——"

"Now do you think any sensible man would break such a promise to me?" she laughed.

"You know the answer already," Wade replied. "You are a very good-looking young woman—almost as good-looking as Kitty."

"Model husband," Clyde commented approvingly. "Kitty is a darling. But to come to the point, Mr. Wade, I want some information about Mr. Dunne."
