TABLE 110.—Lignite produced in North Dakota, 1919–1923, in net tons • Bowman, Golden Valley, and Oliver in 1919; Adams, Bowman, Dunn, Golden Valley, and Oliver in 1920; Adams, Bowman, Dunn, Hettinger, and Oliver in 1921; Bowman and Oliver in 1922; and Billings, Bowman, and Oliver in 1923. Burleigh includes Mercer in 1919. No canvass of wagon mines for 1921 OHIO Ohio rallied in 1923 and produced more coal than in any previous year with the exception of 1917, 1918, and 1920. All the counties of any importance showed increases over 1922, and the gain for the State as a whole was 13,592,652 tons, or 50.4 per cent. Only two other States exceeded this rate of increase in 1923-Maryland and Pennsylvania-and no others approached it. The output amounted to 40,546,443 tons, and the value was $98,610,000, a gain over 1922 of $11,554,000, or 13.3 per cent. The number of employees was very nearly the same in the two years, but the days worked, like the tonnage, increased 50 per cent. Even this was the equivalent of only half a years' potential working days. The average daily output for a number of years and for the months of 1923 is shown in the accompanying diagram (fig. 52). In 1923 the range was from 148,000 tons in June to about 100,000 tons in December. The maximum monthly average did not equal the average for the entire year 1920. Spot prices in Ohio, as elsewhere, were declining in 1923. By December southern Ohio mine-run coal was quoted by Coal Age at $1.70 f. o. b. mines, and Pittsburgh No. 8 mine run at $1.91.

Data from Tables 78 and 79; spot prices as quoted by Coal Age TABLE 112.-Coal produced in Ohio, 1919–1923, in net tons • Gallia includes Morgan and Washington in 1921; Morgan, Scioto, and Washington in 1922. ▸ Morgan includes Scioto and Washington in 1919; Washington in 1920; and Scioto and Washington production, and Gallia decrease in 1923; no production in Gallia County in 1923. Portage includes Summit in 1920; Summit and Wayne in 1921; Wayne in 1922; and Summit and Wayne in 1923. No canvass of wagon mines for 1921. OKLAHOMA The production of coal in Oklahoma in 1923 showed a slight increase over that of 1922-82,527 tons, or 2.9 per cent, but the total value decreased $653,000, or 5.7 per cent. The average number of days worked was larger, but the number of employees fell off. The tons mined per day in the years 1918 to 1922 and the months of 1923 are shown in Figure 49. |
