When the Carnegie group began operations in the early seventies, American steel, as a British writer remarked, was a "hot-house product"; yet in 1900 the Carnegie partners divided $40,000,000 as the profits of a single year. They had demonstrated that the United States, despite the high prices that prevailed everywhere, could make steel more cheaply than any other country. Foreign observers have offered several explanations for this achievement. American makers had an endless supply of cheap and high-grade ore, cheaper coke, cheaper transportation, and workmen of a superior skill. We must give due consideration to the fact that their organization was more flexible than those of older countries, and that it regulated promotion exclusively by merit and gave exceptional opportunities to young men. American steel makers also had scrap heaps whose size astounded the foreign observers; they never hesitated to discard the most expensive plants if by so doing they could reduce the cost of steel rails by a dollar a ton. Machinery for steel making had a more extensive development in this country than in England or Germany. Mr. Carnegie also enjoyed the advantages of a high protective tariff, though about 1900 he discovered that his extremely healthy infant no longer demanded this form of coddling. But probably the Carnegie Company's greatest achievement was the abolition of the middleman. In a few years it assembled all the essential elements of steel making in its own hands. Frick's entrance into the combination gave the concern an unlimited supply of the highest grade of coking coal. In a few years, the Carnegie interests had acquired great holdings in the Minnesota ore regions.
