The miners know this, and it is their constant desire to encounter carbons. Many of them go to the sacred tree near Lenções, where the spirit of Santa Barbara, the patron saint of the miner, is said to have appeared, and place on a limb thereof a stone of the size of the carbon they wish to find. They then pray and it is said that the saint has blessed many of the faithful.

The largest carbon ever encountered was found near Lenções in 1895, on the ledge of a mountain which had been worked some time before. It weighed, when found, 3,165 carats, was purchased from the miner for $16,000 and was finally exported to London, where it sold for $31,145, having lost about 50 carats meantime in drying out. In London it was broken into pieces suitable for drills and these pieces sold for about $40,000, while at the present price of carbon they would be worth about $158,000.

The next largest carbon was found this year, and is still in the bands of the miner. It weighed when found 869 carats, but has lost
