The incomplete analyses below are from Putnam's report. No. 

 1 relates to a sample of a pile of 7000 tons from No. 8 pit, No. 2 to 

 a sample from a pile of 3000 tons representing the general shipping 

 products from the mines exclusive of No. 8 pit, and No. 3 is based 

 on a sample of the concentrates made at Ironville which were used 

 in the forges at that place.

The production of the Hammondville group is partly a matter 

 of estimate, since there are no records relating to the early period 

 of activity. In the paper by Swank, quoted above, is included a 

 table showing the approximate output of Lake Champlain mines 

 from the beginning down to the year 1885, in which Hammond- 

 ville is credited with a total of 1,500,000 tons. This does not seem 

 excessive as Smock reports the production for the period of 13 

 years previous to 1889 as 1,041,015 tons, evidently based on actual 

 records. From the figures quoted in the volumes of Mineral 

 Resources, it is gathered that the production subsequent to 1885
