"Why?"

"Because that pebble is a nugget."

"A nugget?" M. Zermatt said questioningly.

And going to the window he began to look at it in the better light.

"I am certain of what I allege," Ernest declared. "I have examined that pebble, have analysed some portions of it, and I can guarantee that it is largely composed of gold in a native state."

"Are you sure you are not mistaken, my boy?" M. Zermatt asked.

"Quite, Papa, quite!"

Mme. Zermatt had listened to this conversation without speaking a word, without even putting out her hand to take the precious object, the finding of which seemed to leave her quite indifferent.

Ernest continued:

"Now, as we were coming back down the Montrose gorge I noticed a number of pebbles like that. So it is certain that there are quantities of nuggets in that corner of the island."
