BAIN.] MINES AND PROSPECTS. 51 



two veins of fluorspar, each 8 to 12 inches thick. Apparently the 

 shale has been thrust upward, or rather both the foot wall and hang- 

 ing wall of the vein as a whole have moved downward, leaving the 

 shale as a wedge between the two walls. There are small veins of 

 galena one-fourth inch thick which come down to the shale and are 

 there cut off abruptly. It is reported that 200 pounds of lead were 

 shipped from a surface pocket at this shaft. A small amount of 

 blende and occasional pieces of pyrite have been found in the vein. 

 It is said that the last work done on this property showed fluor- 

 spar, calcite, and galena distributed pretty well over the bottom of 

 the shaft. 



The same vein, presumably, has been opened on the ground south 

 of the Big Joe and has yielded several hundred pounds of lead ore. 

 There are there, as at the Big Joe, parallel crevices, and fluorspar, 

 calcite, galena, and blende occur, intimately intermingled in crevices 

 in the quartzitic sandstone. 



Two small prospects have also been opened near Mr. Jesse Crab's 

 house, not far from the Big Joe. They show the usual association of 

 ores, a small vertical vein about 2 feet thick crossing the quartzite. 



In the northeast quarter of the same section a vein 2 feet or more 

 in width of deep-purple spar shows in the bed of a small creek. The 

 vein has a course N. 58° E. and lies between the St. Louis and Ste. 

 Genevieve limestones. No work has been done on this vein, but the 

 spar has the appearance of being very clean. 



Hutchinson mine. — In SE. \ SW. \ sec. 22 Mr. James Hutchinson 

 has an open pit, in which are a series of parallel crevices running 

 through the sandstone with a course about the same as at the Big Joe. 

 The crevices are vertical and narrow. White, purple, and green fluor- 

 spar occur, with a minor amount of galena. 



Rainey mine. — In SAV. \ SE. \ of the same section (22) is an open 

 pit located on the contact between the Ste. Genevieve and the Birds- 

 ville formations. Limestone shows on both sides of the pit, but in 

 the hill above to the west is blue shale, and a short distance bej^ond 

 sandstone occurs. There seems to be some slight faulting here, with 

 downthrow to the north. The course of the vein is N. 25° E. The 

 vein is 12 to 18 inches wide and shows fluorspar, galena, and blende. 

 Minor amounts of zinc carbonate have been formed by the alteration 

 of the blende. 



Baldicin mine. — This is located in SW. \ SW. ^ sec. 23, and con- 

 sists of an open cut about 10 feet deep. It exposes a vertical vein 

 about 6 inches wide cutting the Ste. Genevieve limestone and having 

 a course about N. 40° E. The limestone is slightly brecciated, but 

 the bulk of the vein stuff consists of purple fluorspar and white cal- 

 cite, with minor amounts of galena and blende.
