JACK COUNTY. 509 



The property has recently changed hands and the present owners intend to 

 fully develop their property. This is Coal Seam No. 7 of the general section. 



COPPER. 



A small deposit of copper has been found in the northern part of the 

 county, but no attempt has been made to develop it. It is probably a part of 

 the Permian copper that is found in the Wichita Beds at other localities. 



GALENA. 



I have seen small pieces of galena that were taken from the wells in the 

 western portion of the county, but it has not been found in sufficient quantity 

 to be of economic value. 



This county is not free from the usual tradition of rich Spanish mines. 

 There is an old fort in " Spanish Fort Bend " on Red River that, tradition

 but, like all such traditions, no mines have ever been found.

 DRAINAGE AND TOPOGRAPHY. 



This county is quite rough along the West Fork of the Trinity River, which 

 runs through the northern part of the county from west to east. In fact, the 

 county is hilly throughout its entire extent, with broad, open, level plateaus be- 

 tween the hills and ridges. The drainage is all into the Trinity River except 

 at the southwest corner, where Keechi Creek, a tributary of the Brazos River, 

 has its source. These creeks and rivers have cut down into the strata, mak- 

 ing deep and wide valleys, and the hills are protected on top by thick beds of 

 sandstones, conglomerates, and limestones, which give to the country a much 

 more rough and broken appearance than it really has. Between these hills 

 are many broad valleys or plateaus, some of them even miles in extent, that 

 furnish fine locations for extensive farms. 



GEOLOGY. 



Jack County belongs entirely to the Coal Measures. The strata are com- 

 posed of sandstones, limestones, clays, conglomerates, and fire clay, as well as 

 two coal seams. 



Coal Seam No. 7 runs through the northern part of this county from north- 

 east to southwest, passing near the town of Gertrude, and is the only seam 

 that is of any commercial value. No part of the Albany Beds extends into
