The first year coal production was listed for Texas was 1884, when 125,000 short tons was mined. Production declined from 1885 to 1888. It subsequently climbed at a high rate to 1,107,953 short tons in 1901, then gradually increased to a high of about million tons in 1913. After that year, coal and lignite production gradually declined.
