I will tell you something: three days ago I followed up the river, and about twenty miles above this spot I became attracted by the conformation of the country, and remarked it as being very similar to some very famous spots in South America.

'Here,' I said to myself, 'Maximilian, you have your volcanic disturbance, your granite, your clay, slate, and sandstone upheaved, and seamed with quartz;--why should you not discover here, what is certainly here, more or less ?'--I looked patiently for two days, and I will show you what I found."

It was white, stained on one side with rust-colour, but in the heart veined with a bright yellow metallic substance, in some places running in delicate veins into the stone, in others breaking out in large shining lumps.

"Goose!" said the Doctor; "look again." I looked again; it was certainly different to ironpyrites; it was brighter, it ran in veins into the stone; it was lumpy, solid, and clean.

I said, "It is very beautiful; tell us what it is ?" "Gold!" said he, triumphantly, getting up and walking about the room in an excited way; "that little stone is worth a pound; there is a quarter of an ounce in it.
