ur 



SHULLSBIJRG DISTRICT. 



The mines embraced in this district are situated in T. 1, R. 2 E., and some in the 

 south part of T. 2, R. 2 E., being not a very large but quite productive district. 



There are two furnaces in operation in the district. No. 1 is now operated by Mr. B. 

 Spensley, of Shullsburg, and was formerly owned and operated by Messrs. Quinch & 

 Estey, of that place. It is a blast furnace of two hearths, situated a short distance 

 west of the village, on the Shullsburg branch. No. 2 is also a blast furnace of two 

 hearths, capable of smelting 12,000 pounds of ore in twenty-four hours, with six men. 

 It is also situated near the Shullsburg branch, about four miles below Shullsburg. Prior 

 to June 1st, 1873, it was operated by Messrs. Joseph Hutchinson & Sons. At that time

MINERAL POINT DISTRICT. 



The ore smelted at the Mineral Point furnaces is derived from all the mines and dig- 

 gings in the vicinity of the city. Ore is also brought here in many cases from long dis- 

 tances. The ore of the following districts is also smelted here, viz: MifBin, Linden, Lost 

 Grove, Diamond Grove, Duke's Prairie, and Wiota. 



There are two furnaces now in operation. No. 1 owned by Mr. James Spensley is 

 situated one mile west of the city, on the Spensley branch of the Pecatonica. It is a 

 reverberatory, with a capacity of 6,500 lbs. per day. There is also a blast furnace here 

 of two hearths, but it is seldom used, except for smelting slag and large ore. 



Furnace No. 2, is situated about a mile above No. 1, on the same stream, and is ope- 

 rated by Mr. John Spensley. There is here a blast furnace of three hearths, and a re- 

 verberatory. The latter is the only one now used. 



A fuU statement has been given by Mr. James Spensley of furnax^e No. 1, and is m-
