STATISTICS OF THE PRODUCTION OF LEAD ORE.

SHULLSBURG DISTRICT. 



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

 eouth 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 

 it was leased to Mr. Wesley Spensley, for a term of three years, and is now operated by 

 Messrs. Spensley & Hutchinson. A full account has been furnished of their production.

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: Mifflin, 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 Ibs. 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- 

 Tated 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 full statement has been given by Mr. James Spensley of furnace No. 1, and is in- 

 serted below, with the exception of the years 1862 and 1863, which have been estimated 

 irom an average of the others. The amount of ore smelted at furnace No. 2, from 1863 

 to 1872 inclusive, is estimated by Mr. John Spensley at 7,273,764 Ibs. As the annual
