NORTH CAROLINA

North Carolina has been listed as a coal-producing State at intervals since 1840, and its maximum production was reached in 1922, when 78,570 tons was recorded In 1923 only 36,019 tons was raised, and the value decreased from $388,000 to $132,000.

NORTH DAKOTA

North Dakota was one of those States which again broke all coalproduction records in 1923, though the rate of increase over 1922 was not large-4.4 per cent and the value declined nearly 7 per cent. The output, all lignite, was 1,385,400 tons, valued at $3,275,000. This larger output was achieved by working the mines more days, for the total number of employees was less than in the preceding year.

The daily output for the working year was about 4,500 tons in 1923, a higher average than for any other year, and ranged from 8,400 tons in January to 2,300 tons in June and 4,500 tons in December. (See fig. 51.) For the year 1918 the average was 2,300 tons; for 1922, 4,300 tons.

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.
