98 NEW YORK STATE MUSEUM 
TALC 
The talc mines in the Gouverneur district were under steady 
operation throughout 1912 and contributed about their usual out- 
put which was shipped for the most part in ground condition for 
use in paper, wall plasters and other purposes. The district has 
supplied for some time the greater part of the ground tale produced 
in this country. During the last twenty years the annual outturn 
has ranged from 40,000 tons as a minimum to a maximum of about 
70,000 tons ; the total quantity mined from the first may be placed at 
1,450,000 tons with a value on the average market basis of approx- 
imately $12,000,000. ‘This very considerable item in the mineral 
yield of the State has not caused any serious drain upon the re- 
sources, so far as can be estimated, for the development of new 
mines has fairly kept pace with the depletion of supplies in the 
older workings while there are still many possibilities for the occur- 
rence of additional deposits within the long stretch of henley that. 
constitutes the district. 
The principal features of the occurrence of the talc and present 
methods of its mining and milling were described in the preceding 
issue of this report. The past season has witnessed no important 
developments which call for any revision of the information con- 
tained in the article, except that the list of active companies was 
increased by the entrance of the Standard Tale Co. into the field. 
This company, however, did not operate a new mine, but took over 
the old United States mine, at Talcville, which had been under 
lease to the International Pulp Co. The product was shipped to 
New Jersey for grinding, as the mill formerly connected with the 
mine was burned down some time ago. 
The Uniform Fibrous Tale Co. which began production in 1911 
was active throughout the year, continuing the development of its 
mines as well as preparing for an enlarged milling capacity. The 
mine has been developed practically from the surface. It hes 
a little west of Talcville on the north bank of the Oswegatchie 
river. The deposit appears to be nearly in the same horizon as that 
worked in the United States and No. 2% mines at Talcville. The 
shaft is vertical for the first 90 feet, then follows the northerly dip — 
of the tale; at the end of 1912 it had reached a depth of avlitve 
over 200 feet. The tale body has been explored for a width of 
30 feet without coming into the unaltered tremolite schist which 
forms the walls. It yields a very white talc of fibrous nature. 
An addition to the mill recently completed, provides space for the
