World Production of Coal in 1920

T HE year 1920 will be a memorable one in the history of the world's coal supply. The prices reached were the highest of modern times, and as usually happens at such a time, the quality of the output deteriorated. In the last two years of the war, the world's output had risen close to the pre-war level. After the armistice, however, the cessation of munitions manufacture and the delay in resumption of normal business curtailed the demand for coal. Industrial disputes both in Europe and America closed many mines late in 1919 and further reduced the supply. Thus when in 1920 the world set its face to work again and industrial activity was resumed where resumption was possible, consumers' reserves of fuel proved insufficient and an almost universal feeling of apprehension over the coal supply swept around the world. The reasons for this alarm-lately a thing of the past-become clear when the world's production in 1920 is cast up.
