Identification of Specimens. 
A large number of mineral specimens have been received from pros- 
pectors and others with requests for identification and other information 
concerning them. In many cases the specimens are accompanied by re- 
quests for chemical analyses. The Survey does not maintain an analyti- 
cal laboratory, and even if it did it would probably not be, wise to com- 
pete with professional analysts in making analyses for private indi- 
viduals. However, in a great majority of instances the specimens have 
been fully identified, where necessary by qualitative dry and wet tests, 
and the information furnished free of charge, thus saving the cost of a 
chemical analysis. 
.1/ i nera 1 St a t is tics. 
The Survey has undertaken the collection of mineral statistics for the 
year 1010, in co-operation with the TT. S. Geological Survey. The statis- 
tics include complete totals of quantity and value for all metallic and 
noil-metallic products of the state. As soon as the returns for any 
product have been received and tabulated the same will be distributed 
to the press of the state and the complete statistics for all the products 
will be issued in a separate publication of this department. 
If is planned that the collection and publication of complete statistics 
of mineral production in the state will hereafter be an important and 
useful feature of the work of this department. A report bearing the 
statistics of mineral production should be issued on the following plan: 
(1 ) The report should appear promptly as soon as possible after the 
close of each year; (2) it should give complete statistics for all branches 
of the mining and allied industries, including metallic and noil-metallic 
products ; (3) it should be accompanied by maps and sketches giving loca- 
tion of mines, quarries, etc., and (4) it should contain a general resume 
for the year of mining conditions in the state, as nearly as possible bv
