matrix of the breccia. They are associated with calcite and white 

 and purple fluorite, which form the main cementing materiaL The 

 blende is a bright rosin '' jack," and the company is now reported to 

 be erecting a mill for concentrating the ore. 



Near the Avorks is the kaolin pit from which the jiroperty takes its 

 local name, " Old Clay diggings." The pit has been abandoned for 

 a half century, but its size indicates that considerable bodies of 

 kaolin were shipped. The kaolin occurs apparently on the contact 

 between the limestone and the sandstone, Avhich, as now exposed, has 

 weathered to a bright-red color. The origin of tlu^ kaolin is un- 

 known. No igneous rocks have been found in or near the mine. 



McCleUan mine. — Northeast of the Pittsburg mine (section 11) 

 limestone is again seen, but its age was not determined. The general 

 country rock is sandstone. A shaft 40 feet deep has developed evi- 

 dences of faulting and a body of very clear fluors])ar G to 7 feet 

 thick. No sulphides were noted. There seems to be a system of 

 veins running from N. 15° E. to N. 85° E. These mark fault planes, 

 some of which bring limestone to the surface and some do not. 



In an adjacent section (8) there is a well-developed quartzite reef, 

 marking a fault plane in the Chester sandstone and shale. A small 

 body of zinc carbonate was found near it. 



Luella mine. — Southwest of the last-mentioned locality (sec. 10, 

 T. 12 S., R. C) E.) and apparently on the same belt of faulting the 

 rocks are disturbed and fluorspar is introduced along the sides of an 

 infaulted block of limestone. A considerable amount of white spar 

 appears here at the surface, some of which seems to be sand}^ There 

 is also a pit showing a small body of kaolin, but the relations could 

 not be determined owing to the limited amount of development. 



Taylors Spring. — Comparatively' little prospecting has been done 

 in the region about Aliens Spring and Eock, though faulting is com- 

 mon and float mineral has been found at several points. Near Tay- 

 lors Spring (sec. 81, T. 12 S., R. (> E.) the sandstone has a dip of 22° 

 S., strike N. 55° E., and shows quartzitic facies. In the field near hy 

 small pieces of fluorite and galena have been found. 



Moore mine. — On the Moore farm, near Taylors Spring, an open 

 cut has been made in sandstone and shale, and small pieces of fluorite 

 and galena have been found. 



W7'ight 7nine. — In section 8, T. 12 S., R. 5 E., a small shaft has been 

 sunk in shales and sandstone, probably of Birdsville age. The 

 rocks dip at high angles, 30° to 47°, and in conflicting directions in 

 this vicinity, and evidently have been considerably disturbed. Cal- 

 cite and pyrite were the only minerals found in sinking, and no well- 

 developed vein was located. 



Southwest of this work, in section 9 (NE. ^ NE. I), the beds are 

 again disturbed, and belts of Birdsville of considerable width are
