be removed from the rock with care by the hands. Pieces 

 could be easily cut for small objects, and would be extremely 

 handsome for such uses, owing to the brilliant and delicate 

 coloring. It has been used to some extent for ring stones, 

 cuff buttons, seal rings, and other purposes as jewelry with 

 considerable success. 



Prosopite at first was supposed to be identical with utahite, 

 but an analysis made by Mr. W. J. Hillebrand proved it to 

 be a fluoride of alumina, known already as a rare species of 

 mineral from Saxony, Germany, and from Pikes Peak, Colo., 

 where it occurs, but without the rich blue green color of that 

 found in Utah. Here it was obtained by Mr. Josiah Beck in 

 1895 in the Dugway mining district, in Tooele county, in a 

 region of low and desert hills. The mineral was not fully iden- 

 tified until 1899, when the analysis was made and the result 

 published. The prosopite is a beautiful stone, but whether 

 it exists in sufficient amount to be of practical use has not 

 yet been determined. 



There is a small but fairly constant sale in the coal region 

 of eastern Pennsylvania of articles of ornament carved from 

 anthracite coal, such as inkstands, paper weights, etc. These 

 are usually made partly polished and partly rough, so as to 

 show a contrast between the two different kinds of black sur- 

 faces. They are sold almost entirely as local souvenirs to 

 persons visiting that part of the country. The sale of such 

 articles has been estimated for some years past at a total vary- 

 ing from $1,000 to $2,000. 



Catlinite, or pipestone, celebrated in Indian history and 

 immortalized by Longfellow in Hiawatha, is used to some ex- 

 tent for making ornaments and souvenirs that are sold to 

 visitors in the region of its occurrence — Pipestone county, in 

 southwestern Minnesota. It is not really a definite mineral 

 species, but essentially an indurated red clay. 



The old and celebrated Shawneetown region in southern 

 Illinois has lately been yielding fluorite of remarkable beauty. 

 In a lot of specimens recently sent to the writer for examina- 

 tion were cleavage pieces of much beauty from several of these 

 localities, notably the Empire mines and Cave-in-Rock. From 

 the former were large cleavages of rich reddish purple,
