' This sandstone is a coarse compact rock of a greenish gray color, 

 though many of the inckided pebbles are of a rose-red tint. The ce- 

 menting material, which is of a greenish color, shows under the micro- 

 scope a fibrous structure and remains always light between crossed 

 Nicols. It bears very many inclosures of rounded and augular grains 

 of hematite, which by reflected light are of a bluish luster somewhat 

 resembling menaccanite, but giving no disthict reaction for titanic 

 acid when subjected to the proper tests. They are of all sizes up to a 

 millimeter in diameter. A section through one of the rose-colored peb- 

 bles shows it to be traversed in all directions by numerous fractures iu 

 which are included, as if deposited by infiltration, innumerable minute
