In 1869 an entirely new departure in Reading policy occurred. Whereas the road had previously owned no coal lands, with the advent of Mr. F. B. Gowen to the presidency it began to purchase on an enormous scale. “The repeated and serious interruptions of the business of the company,” said the annual report for 1871, “caused by strikers in the coal regions during the last few years, and the many fluctuations in the coal trade, produced by alternate periods of expansion and depression resulting therefrom, have attracted the attention of the managers of the company to the necessity of exercising some control over the production of coal, so as to prevent a recurrence of the difficulties heretofore experienced; and it was believed that the best way to accomplish this result, without injuriously affecting individual interests, was for the company to become the owner of coal lands situate upon the line of its several branches.”[156] Further, it was felt that some steps were necessary to retain for the Reading even the coal tonnage which it enjoyed. In 1871 every rival carrier had invested large sums in coal properties, and all the fields but the Schuylkill and Mahanoy (western middle) were occupied, while carriers had begun to enter the Mahanoy district, and it was reported to be their intention to build lines straight through to the Schuylkill fields. The anthracite coal regions of Pennsylvania lie in four main districts: the Northern or Wyoming; the Southern or Schuylkill; and two smaller intermediate fields known respectively as the Eastern Middle or Lehigh region and the Western Middle or Mahanoy and Shamokin basins. The Northern field is the more easily worked, and the Southern field is the richer.[157] Between 1869 and 1881 the Reading Railroad and its alter ego, the Coal & Iron Company, formed for the purpose, spent $73,326,668 for lands in the Schuylkill and Western Middle districts, securing 142 square miles, or 60 per cent of all the anthracite lands of these districts, and 30 per cent of all in Pennsylvania. Of the purchase money $69,816,204 were supplied either by the Railroad Company or by sale of Coal & Iron Company bonds which the Railroad Company guaranteed. The Coal & Iron Company incurred non-guaranteed liabilities for the rest.[158] This gave ample resources for the permanent supply of coal tonnage to the railroad, and was sufficient also to give a considerable measure of control over production in the Southern district. Independent operators did continue, however, and the Reading coal was subject to the competition of coal from other fields. More important still, in attaining control, “all kinds of coal properties, good, bad, and indifferent, were purchased without regard to original cost, location, or revenue producing capacity.”[159] In 1880 an engineer of reputation was appointed to evaluate the Reading coal lands, and recommended the surrender of five properties that
