The plant known as "Indigofera Tinctoria" is sown in March in soil carefully prepared, grows to about 5 feet, is cut down early in July, is fermented in vats, and the liquor is beaten till it precipitates the precious blue dye, which is boiled, drained, cut in small cakes, and dried. From first to last the growth and the manufacture are even more precarious than most tropical crops.
These shell fish are laid in a long trench, covered over with the large leaves of the panke tinctoria, over which a layer of stones is laid, on which a hot fire is kindled and kept up for several hours. The roasted fish are then taken out of the shells, strung upon lines, and hung up for some time in the smoke of wood fires.
A red precipitate is obtained, which fixes itself directly on cotton thread immersed in the liquid, and dyes it a delicate rose pink, which is, unfortunately, very fugitive. Silk can be dyed like cotton. The colour is not fast against light. Turmeric is the root portion of a plant called curcuma tinctoria, that grows in Southern Asia. The principle forming the colouring matter is "Curcumin."
They are commonly known by the name of brinjals, from the beringelhas of the Portuguese. Marsdenia tinctoria, OR BROAD-LEAFED INDIGO. E.W. Marsden delt. Swaine fct. It is afterwards drained off, and made use of in the liquid state.

The manufacturers of Cumanacoa, of San Fernando, and of Arenas, produce indigo of greater commercial value than that of Caracas; and often nearly equalling in splendour and richness of colour the indigo of Guatimala. It was from that province that the coasts of Cumana received the first seeds of the Indigofera anil,* which is cultivated jointly with the Indigofera tinctoria.
GENISTA tinctoria. The flowers are in use among the country-people for dyeing cloth yellow. GERANIUM sylvaticum. MOUNTAIN CRANESBILL. The Icelanders use the flowers of this plant to dye a violet colour. HIERACIUM umbellatum. HAWKWEED. The whole herb bruised and boiled in water gives out a yellow dye. HUMULUS Lupulus.
The flowers are few but pretty, and with the dwarf habit render the plant an excellent subject for rockwork. G. TINCTORIA. Dyers' Greenweed. This is a spineless species, and bears a profusion of yellow flowers from July onwards. The double-flowering variety, G. tinctoria flore-pleno, is, in so far as ornamental qualities are concerned, superior to the parent form.
His excursions were chiefly in the county of Surrey, and especially in the neighborhood of Guildford and the beautiful vale of the Sittingbourne, where he had the satisfaction of being the first to notice several plants of interest, as Polygonum dumetorum, Isatis tinctoria, and Impatiens fulva, an American species of balsam, affording a very remarkable example of complete naturalization in the Wey and other streams connected with the lower course of the Thames.
