Eisen, 1901, p. 291; see also p. 213. 4Id., 1901, p. 293. The cost of production of coke presents quite a different problem from the cost of coal. In the first place, the cost of coke depends chiefly on the cost of coal, and must rise and fall, generally speaking, in proportion with it. Leaving the cost of coal out of account, the manufacture of coke seems to be an industry of something like constant returns. But the addition of the manufacture of by-products greatly complicates the problem of the determination of cost. Most of the coke in the ...
