gave me a specimen of native copper, which lie said was found in Northern Texas. Its finder reported such copper to be quite abundant in that portion of the State. I do not think it was found east of Haskell county. It may have come from the Lake Superior region, the specimens of which it much resembles.

LEAD.

Lead has been found in small quantities in Llano county, where it is associated with silver. At an old Spanish mine, not, far from Honey creek cove, near the top of a mountain a few hundred feet high, mining appears to have been done for both lead and silver. The mine is in the calciferous sand-rock, associated with the magnesian limestone of the lower silurian. Large rhomboidal crystals of calcite are abundant near the entrance of the mine. These are sometimes termed the "blossoms of lead," by some miners in Missouri, where lead is found in the same geological formation. A piece of slug, given me by Dr. C. S. Smith. of Llano, who obtained it at the old furnace, where the ore was smelted, contains lead, which has been smelted. Around the entrance of the mine are some rocks which contain titaniferous iron ore.

Mr. Magee, a few years ago, had the water drawn front the mine, which is said to be forty or fifty feet deep, but from some cause unknown to me, nothing more was done at that locality.

A Mr. Woodward, who lives on Cherokee creek, in San Saba county, lately showed me some fine specimens of galena, which he said he obtained not far from his residence, but he refused to designate the spot, hoping that ere long he would be able to buy the land on which the mine is situated. Here the lead occurs in the same kind of rocks which contain the Spanish mine of Llano. Mr. W. said that lie knew the lead ore at his place to be very abundant, also saying that lie was familiar with the lead-bearing rocks of Illinois and Missouri, having there lived near the mines.

In Burnet county, about four miles from Bluff ton, is a lead and silver mine, which has been worked to some extent. Several specimens of ore from this mine are in the State Cabinet. Working at this place has been discontinued, its owner having been engaged in digging for silver in Llano county during the past summer. The ore near
