However, demand for coal nationwide dropped precipitously and continually in the several years after World War I. In a response, Hillman closed its mines at Ella and Patterson, Allegheny County, and at Naomi, Fayette County, but maintained production at Boswell and Jerome. By mid-1921, the Company told its shareholders in its Annual Report, “…the demand coal became so small and the competition from non-union fields so severe that it was evident that the non-union mines of your Company could not continue to operate unless wages were readjusted. As a result of this condition, wages were reduced…at your Jerome Mines on July 16, 1921.” Hillman continued that the reduction allowed the Jerome mine to operate “on a competitive basis” and “with regularity,” with the result being that “earnings of the men at your non-union mines for the year 1921 are far in excess of those received by men at union mines….”, who, Hillman implied, suffered frequent short-term furloughs as the result of slack demand. Hillman told its shareholders that, prior to the pay cut, “men working by day were being paid $7.50 for eight hours work, and men working by the ton were able to earn $10.00 to $14.00 per day.” (Note that these wages reported by Hillman to its stockholders were flatly contradicted by other reportage, for instance, Blankenhorn maintained that union gross wages in 1922 more typically ranged from $14.60 to $17.50 per "week", and after deductions for goods purchased through company stores, a typical miner's weekly net take-home pay often was less than $1.00.) On all its coal operations, including Jerome and Boswell, Hillman Coal and Coke reported an operating profit of approximately $925,000, on revenues of $8.225 million in 1919, and an operating profit of approximately $336,000, on revenues of $4.475 million in 1921.
