Of the tar and flue-dust is also condensed, which is of importance where bituminous coal is employed for firing.
If bituminous coal is distilled at a low tempera- Destruc- ture, the tar is found to contain considerable quantities of tive dis- light paraffin oils; and there is no doubt that paraffin tillation hydrocarbons are present in the original coal.
Springfield is a trading and shipping centre for a prosperous agricultural region, and ships large quantities of bituminous coal from the immediate vicinity.
Coal, chiefly bituminous, occurs in large quantities in Nova Scotia, British Columbia and in various parts of the north-west (lignite), though most of the anthracite is imported from the United States, as is the greater part of the bituminous coal used in Ontario.
The true bituminous coal produced, which in 1897 was only equal to that of the lignitic and semi-bituminous varieties (1.75 million tons), had come by 1902 to constitute three-fourths (5.46 million tons) of the entire coal output.
The mineral wealth of Ohio consists largely of bituminous coal and petroleum, but the state also ranks high in the production of natural gas, sandstone, limestone, grindstone, lime and gypsum.
The bituminous coal of West Virginia is a particularly good coking coal, and in 1905, 1906, 1907 and 1908 West Virginia ranked second (to Pennsylvania) among the states of the Union in the amount of coke manufactured; the Flat Top district is the principal cokemaking region.
The production of bituminous coal has also increased very rapidly.
The state has two small areas in which bituminous coal occurs; one in the basin of the Dan and one in the basin of the Deep. Very little coal was produced in the state until the Civil War, when, in 1862 and again in 1863, 30,000 short tons were obtained for the relief of the Confederate government, an amount which up to 1905, when the yield was only 1557 short tons (falling off from 7000 short tons in 1904), had not since been equalled; in 1906, in 1907 and in 1908 no coal was mined in the state.
Anthracite is mined in the St Lucia Bay district, and bituminous coal is found in the Nqutu and Kyudeni hills.
