They straightway began a vigorous search up and down stream, confident of finding other similar nuggets, but none was discovered, and finally they reached the place where their baggage had been left, and where Tim and Jeff were awaiting them.

"Look!" called the delighted Frank, holding up the nugget. "See what we found!"

"Begorra, but I shouldn't wonder if that's worth something," remarked Tim, catching the contagion. Jeff merely smiled and reached out his hand without any appearance of excitement.

"Let me have a look at it."

He never used glasses, nor did he bring any acid with which to test such yellow metals as they might find, for he needed neither. He had been trained too well in his early manhood.

The instant he noted its great weight he was convinced of the truth. But, without speaking for a minute or two, he turned the nugget over, held it up to the light, and then put it between his big, sound teeth as if it were a hickory-nut which he wished to crack. He looked at the abrasion made by his teeth, tossed the nugget several feet in the air, and, catching it in his palm as it descended, said:

"That's pure gold. Haven't you any more?"

"No," replied Frank; "we searched, but couldn't find any."

Jeff moved his hand up and down and closed one eye, as if that would help him to estimate the weight more exactly.

"I should say that it is worth from six to eight hundred dollars; you younkers have made purty good wages for to-day. I hope," he added quizzically, "you'll be able to keep it up."
