Denny snorted: "Oh, sure! He's good, all right. He's 'most too good—to be true. Billy, my boy, when you've seen as many crooks as I have you'll know 'em, no matter how they come dressed."

As he folded the cot Mr. Hyde opined that worldly experience must indeed be a fine thing to possess.

"You go gamble on it!" Slevin agreed. "Now then, just tell that Hawkshaw we don't want no dam' spies in our house. We're square guys, and we can't stomach 'em."

That evening Black Jack called upon the handy-man to help with the clean-up, and put him to tend the water while he and Denny, under the watchful eye of the owner's representative, lifted the riffles, worked down the concentrates, and removed them from the boxes.

Bill was an experienced placer miner, so it was not many days before he was asked to help in the actual cleaning of the sluices. He was glad of the promotion, for, as he told himself, no man can squeeze a lemon without getting juice on his fingers. It will be seen, alas! that Mr. Hyde's moral sense remained blunted in spite of the refining influence of his association with Doctor Thomas. But Aurora dust was fine, and the handy-man's profits were scarcely worth the risks involved in taking them.

One morning while Bill was cleaning up the superintendent's cabin he noticed a tiny yellow flake of gold upon the floor in front of Slevin's bed. Careful examination showed him several "colors" of the same sort, so he swept the boards carefully and took up the dust in a "blower." He breathed upon the pile, blowing the lighter particles away. A considerable residue of heavy yellow grains remained. With a grin Bill folded them in a cigarette paper and placed them in his pocket. But it puzzled him to explain how there came to be gold on the cabin floor. His surprise deepened when, a few days later, he found another "prospect" in the same place. His two sweepings had yielded perhaps a pennyweight of the precious metal—enough to set him to thinking. It seemed queer that in the neighborhood of Black Jack's bunk he could find no pay whatever.

Slevin had left his hip boots in the cabin, and as Laughing Bill turned down their tops and set them out in the wind to dry his sharp eye detected several yellow pin-points of color which proved, upon closer investigation, to be specks of gold clinging to the wet lining.

"Well, I be danged!" said Mr. Hyde. Carefully, thoughtfully, he replaced the boots where he had found them. The knowledge that he was on a hot trail electrified him.

At the next clean-up Laughing Bill took less interest in his part of the work and more in Denny Slevin's. When the riffles were washed, and the loose gravel had been worked down into yellow piles of rich concentrates, Slevin, armed with whisk broom, paddle, and scoop, climbed into the sluices. Bill watched him out of a corner of his eye, and it was not long before his vigilance was rewarded. The hold-up man turned away with a feeling of genuine admiration, for he had seen Slevin, under the very nose of the lookout, "go south" with a substantial amount of gold.

The foreman's daring and dexterity amazed Bill and deepened his respect. Slevin's work was cunning, and yet so simple as to be almost laughable. With his hip boots pulled high he had knelt upon one knee in the sluice scooping up the wet piles of gold and black iron sand, while Berg held a gold pan to receive it. During the process Black Jack had turned to address the vigilant owner's representative, and, profiting by the brief diversion, Bill had seen Denny dump a heaping scoop-load of "pay" into the gaping pocket-like top of his capacious rubber boot.
