in this country. At the time the estimate was made, now above a 
year ago, he found it impossible to obtain any information worthy of 
confidence relating to the subject, out of the Iron districts of New 
England and New York; accordingly, he was left to bare conjec- 
ture concerning those parts of the United States which recent inves- 
tigation shows to be by far the most productive in this article of any 
portion of the country. The following statements are derived from 
the Report on the product and manufacture of Iron and Steel, made 
at the direction of the General Convention of the Friends of Do- 
mestic Industry, assembled at New York, Oct. 26, 1831 ;—B. B. 
Howell, secretary. Of which report it is not too much to say, that 
it bears the marks of an indefatigable and honest examination of the 
whole subject. Nor can there be a doubt, that the annual produce is 
yet to be increased by returns from remote sections of the country, 
which have not hitherto reached the committee. 
The number of furnaces in operation during the year 1830, was 
239, and the quantity of iron yielded by them, was 191,536 tons; 
of which 112,566 tons were converted into bar iron. ‘The value of 
all which, according to the mode of estimation adopted by the com- 
mittee and explained in their report, was $13,329,760.
