Scores of "coal drags" containing sixty to a hundred railroad gondolas each ran daily from the field, and during most of these years the only factor which limited production was a shortage of cars. Sometimes the railroad companies were unable to provide the "empties" which the billing clerks requested, and idle tipples were more often caused by this failure than by lack of orders.
I do not mean to imply that the boom was wholly without interruption. Between 1920 and 1922 a recession struck the nation and its impact was felt severely in the coalfield.
