IOWA

The production of coal in Iowa in 1923 was 5,710,735 tons, with a value of $20,517,000, an increase over that of 1922 of 1,375,574 tons, or 31.7 per cent, in quantity, and of $4,398,000, or 27.3 per cent, in value. The number of employees, 11,448, was fewer than in 1922, but the average number of days worked was greater-181, as compared with 131.

The average quantity produced per day in Iowa and the neighboring trans-Mississippi States for the years 1918-1922 and for each month in 1923 is shown in Figure 49. Conditions were not unlike in these States, varying in degree only.
