Previous to 1872, nearly all the calicoes of the world were dyed or printed with a coloring principle extracted from the root known as "madder"; the cultivation and preparation of which involved the use of thousands of acres of land in Holland, Belgium, Eastern France, Italy, and the Levant, and the employment of many hundreds of men, women, and children, and of large amounts of capital; the importation of madder into England for the year 1872 having been 28,731,600 pounds, and into the United States for the same year 7,780,000 pounds. To-day, two or three chemical establishments in Germany and England, employing but few men and a comparatively small capital, manufacture from coal-tar, at a greatly reduced price, the same coloring principle; and the former great business of growing and preparing madder with the land, labor, and capital involved is gradually becoming extinct; the importations into Great Britain for the year 1885 having declined to 2,472,000 pounds, and into the United States to 1,458,313 pounds.
