INDUSTRIAL STATISTICS. 



617 



In the above tabulation the producing capacity of the iron 

 and steel works of the country has been stated by aggregat- 

 ing the individual returns of each establishment. Since, 

 however, in practice, blast-furnaces and rolling-mills can nev- 

 er be operated uniformly to their full capacity, these aggre- 

 gates with respect to them will never be actually realized. 

 With regard to the forges, bloomeries, and steel-works, how- 

 ever, the summary is believed to represent, without much 

 overstatement, their actual working capacity. 



THE WORLD'S PRODUCTION OF IRON AND COAL.

To the foregoing figures of pig-iron there should properly 

 be added the known and estimated make of iron direct from 

 the ore, by primitive methods, as practised in certain parts of 

 this country, in China, India, and other countries. This Mr. 

 Swank estimates at about 50,000 tons yearly; and if so add- 

 ed, would swell the figure of total production to 13,408,628 

 gross tons, or, in round numbers, 13,400,000 tons.
