The above table gives in round numbers the product of the Platteville district since 

 1861; it is, however, only an approximation made by the smelters themselves, and be- 

 lieved to be tolerably correct. Furnace No. 1, owned by Messrs. Straw & Spensley, is a 

 blast furnace having two hearths, and is situated about half a mile south of the village. 



Furnace No. 2, owned by Mr. Coates, is situated near the railroad depot. It is a blast 

 furnace of two hearths, and has not been worked since some time in 1873. Nothing 

 more than a verbal statement of its annual average could be obtained. 



POTOSI DISTRICT. 



There have been, at various times since 1861, four furnaces operating in the vicinity, 

 of which only two are now worked. They are as follows, in kind and condition: 

 Vance's Furnace ceased work in 1868 



Gibson & Co. ceased work in - 1871 



A. W. Emery's furnace, situated near Rockville, is a reverbatory, with a capacity of 

 6,000 pounds to every 24 hours. Thomas Hymer & Co.'s furnace, situated near British 

 Hollow, is a blast furnace of one hearth. 



Previous to 1868, all the ore from the Beetown district was smelted at these furnaces, 

 in addition to that which they now smelt, which comprises the mines of Potosi, British 

 and Dutch Hollows, and Rockville. 



A detailed statement of the ore smelted at the several furnaces could not be obtained, 

 but from the verbal statements of the several smelters, the following estimate has been 

 prepared which is believed to be nearly correct:
