86 THE IRON ORE DISTRICT OF EAST TEXAS. 



Cynthia Latimer survey, on the headwaters of the creek, to the J. H. Jack- 

 son headright, near the junction of the Frazier and Johns creeks. 



In addition to this conglomerate ore, there is found at various places 

 throughout the county a conglomerate of sand, pebbles, and gravel of a much 

 softer and apparently more recent origin. This ferruginous conglomerate 

 can not be classified as iron ore, as no amount of concentration and washing 

 could make it pay to work. 



This conglomerate is always associated with water wherever found ; is either 

 close to the high water limit or within a few feet of that line. Outcrops of 

 this material occur on Jim's Bayou, about two miles south of Linden, on the 

 Jefferson road. In this place it consists of sand, ferruginous sandstone, and 

 pebbles, of which a considerable quantity are siliceous. The deposit lies about 

 twenty feet above the water of the creek (low water limit) and is one foot 

 thick. The distance from the bed to the water is covered with pebbles and 

 pieces of sandstone, and the underlying beds could not be seen, but are proba- 

 bly a mottled red and white sand similar to that which appears on the south 

 side of the creek. Another deposit of a similar nature lies on the D. Glaze 

 headright, about eight miles from Linden, on the Daingerfield road. This 

 deposit, which does not exceed two inches in thickness, lies near the top of 

 a hill about sixty feet above the neighboring stream. A cut in the hill shows 

 the following section: 



1 . Thin gravelly ore, covering top of the hill and scattered generally over the 



side 1 to 2 inches. 



&. Brown sand, weathering to a light gray 4 feet. 



3. Conglomerate of ferruginous sandstone and quartz pebbles, pebbles rounded 



and waterworn, and some a pure white, while others are stained yellow . 2 inches. 



4. Brownish yellow sand, containing nodules of ferruginous sandstone, to the 



bottom of the hill 60 feet. 



64£ feet. 



Whatever may have been the origin of these conglomerate ores, their pecu- 

 liar position and relation to the water courses of the region seem to point to 

 their being of a comparatively recent origin; that is, that their formation be- 

 gan at the same time the present system of drainage commenced. The older 

 and higher conglomerates are therefore less recent, although of the same age, 

 as the lower and softer conglomerates, such as those on Jim's Bayou and other 

 places. 



As a material from which to manufacture iron these conglomerate ores, or 

 the best of them, will not work profitably with the present facilities for the 

 obtaining of fuel in Cass County, and can not compete with the nodular con- 

 cretionary ores so far as expense is concerned.
