"Yes, oh yes. Now what did I do with—— Finished 'em up and put 'em away somewhere," said the assayer, dusting his hands and moving towards his desk. "Such a lot of stuff's been coming in—here they are, I reckon." He drew a half dozen small printed forms from a cavity in the desk, glanced them over briefly and handed the lot to Van. "Nothing doing. Pretty good rock for building purposes."

"Nothing doing?" echoed Van incredulously, staring at the assay records which showed in merciless bluntness that six different samples of reputed ore had proved to be absolutely worthless. "The samples you assayed first showed from ten to one hundred and fifty dollars to the ton, in gold."

"What's that got to do with this?" inquired the master of acids and fire. "You don't mean to say——"

"Do with it, man? It all came out of the same identical prospect," Van interrupted. "These were later samples than the others, that's all."

The assayer glanced over his shoulder at the hope-destroying slips.

"The 'See Saw' claim," he said perfunctorily. "You bought it, Van, who from?"

"From Selwyn Briggs."

"Sorry," said the assayer briefly. "H'm! That Briggs!"

"You don't mean—— It couldn't have been salted on me!" Van declared. "I took my own samples, broke down a new face purposely, sacked it all myself—and sealed the sacks. No one touched those sacks till you broke the seals in this office. He couldn't have salted me, Frank. What possible chance——"

The assayer went to a shelf, took down a small canvas bag, glanced at a mark that identified it as one in which samples of "See Saw" rock had arrived for the former assay, and turned it inside out.
