J. Wharton on the Manufacture of Spelter. 171 
This arrangement offered to the Company as nearly absolute 
certainty as the nature of the case permitted, that they should 
at small expense and without risk or trouble to themselves 
te into possession, after two and a half years, of a complete 
actory and an established business, while meanwhile deriving 
a fair profit from the sale of ore, which at that time cost about 
$2 per ton delivered in the factory yard.* 
pon my side, relying upon the correctness of my own esti- 
mates and upon my ability to establish the business, and assum- 
ing that the average price of spelter in this country for the 
Es twenty-five years (viz: about 6} cts. per lb.) would 
be about maintained for the ensuing two or three years, I could 
fairly count upon a reasonable profit even after making some 
allowance for mischances. ; 
A severe winter prevented much progress in building until 
the spring of 1860, though one block of furnaces was actually 
put up under cover of a tight temporary wooden building; a 
freshet in the spring destroyed the foundations of some of the 
Which I had taken of importing a number of train 
works were completed. As the factory worked irregularly in 
the year 1860, and the furnaces were brought into use gednely 
one block after another, as they were finished, I give no detai 
of the operations for that vear. ae : 
To indicate what manner of difficulties lie in wait for the 
Tansplanter of an industry into this country, I may here re- 
mark that though the factory as at first planned and built was 
‘Substantially right in all important points, and my estimates of 
°est of production were justified in practice, yet a number of
