History, Use, Propagation, Culture,

1589. Indigofera. That is to say, a plant bearing indigo. The species are elegant little shrubs, free- 
flowerers, and of easy culture. Most of them will yield the dye, but those chiefly cultivated for this purpose 
are the I. Anil {.Alnyl, Arab.), in the West Indies, and the I. tinctoria, argentea, and some other species in 
the East Indies. The indigo is one of tlie most profitable articles of cultui-e in Hindustan ; because an 
immense extent of land is required to produce but a moderate bulk of the dye ; because labor and land here 
are cheaper than any where else ; and because the raising of the plant and its manufacture may be carried on 
without even the aid of a house. The first step in the culture of the plant is to render the ground, which 
should be friable and rich, perfectly free from weeds, and dry if naturally moist. The seeds are then sown in 
shallow drills about a foot apart. The rainv season must be chosen for sowing, otherwise if the seed is 
deposited in dry soil, it heats, corrupts, and is lost. The crop being kept clear of weeds, is fit for cutting in 
two or three months, and this may be repeated in rainy seasons every six weeks. The plants must not be 
allowed to come into flower, as the leaves in that case become dry and hard, and the indigo produced is of less 
value ; nor must they be cut in dry weather, as they would not spring again. A crop generally lasts two years. 
Being cut, tlie herb is first steeped in a vat till it has become macerated and parted with its coloring matter ; 
then the liquor is let of into another, in which it undergoes the peculiar process of beating, to cause the fecula 
to separate from the water. This fecula is let off into a third vat, where it remains some time, and is then 
strained through cloth bags, and evaporated in shallow wooden boxes placed in the shade. Before it is per- 
fectly dry, it is cut in small pieces of an inch square ; it is then packed in barrels, or sowed up in sacks for 
sale. Indigo was not extensively cultivated in India before the British settlements were formed there ; its 
profits were at first so considerable, that, as in similar cases, its culture was carried too far, and the market 
glutted with the commodity. The indigo is one of the most precarious of oriental crops ; being liable to be 
destroyed by hail storms, which do comparatively little injury to the sugar-cane and other plants. 
The indigo cultivated in the West Indies, thrives best in a free rich soil, and a warm situation, frequently 
refreshed with moisture. Having first chosen a proper piece of ground, and cleared it, hoe it into little
