Which industry fell three rankings from 1879 to 1909?

The answer would be the leather product industry. During the period of 1879 to 1909, there was a rise in less expensive products overall. So it happened to the iron and steel industry which rose because it had just become cheaper to manufacture at high quantities; but what increased its presence in the economic field, was the cotton industry, that was rising quickly, which made the leather products, that were more costly and time-consuming to manufacture to fall three rankings from 1879 to 1909.
