"Si, señor; I watched, they were there two hour."

Westcott stared into the fireplace; then the gravity of his face relaxed into a smile.

"Things are growing interesting, José," he said cheerfully. "If I only knew just which way the cat was about to jump I'd be somewhat happier. There seemed to be more light than usual across the gulch as I came up—what's going on?"

"They have put on more men, señor—a night shift. Last night I went in our drift clear to the end, and put my ear to the rock. It was far away, but I hear."

"No, no, José; that's impossible. Why, their tunnel as over a hundred yards away; not even the sound of dynamite would penetrate that distance through solid rock. You heard your heart beat."

"No, señor," and José was upon his feet gesticulating. "It was the pick—strike, strike, strike; then stop an' begin, strike, strike, strike again. I hear, I know."

"Then they must be running a lateral, hoping to cut across our vein somewhere within their lines."

"And will that give them the right, señor?"

Westcott sat, his head resting on one hand, staring thoughtfully into the dying fire; the yellow flame of the oil lamp between them on the table flickered in the draft from the open window. Here was a threatening combination of forces.

"I am not sure, Jose," he answered slowly. "The mining law is full of quirks, although, of course, the first discoverer of a lead is entitled to follow it—it's his. The trouble here is, that instead of giving notice of discovery, I have kept it a secret, and even blocked up the tunnel. If the La Rosita gang push their drift in, and strike that same vein, they will claim original discovery, and I reckon they'd make it stick. I didn't suppose Lacy had the slightest idea we had struck colour. Nobody knew it, but you and I, Jose."
