Grotocicat News.— General —G. F. Becker (Amer. Fourn. of 
Science, Sept., 1884) has a note upon the relations of the mineral ` 
belts of the Pacific slope to the great upheavals. A great majority 
of all the profitable ore deposits west of the crest of the Wasatch 
occur in belts a few miles in width which follow the western 
edges of distinct geological areas. Thus the lead-silver belt of. 
= Utah follows the Cretaceous, the belts of Nevada and Arizona 
he Paleozoic, and usually the Carboniferous; the gold belt of 
‘astern California the Jura-trias, and the quicksilver belt of East-
