 f. 1. Flowers large, yellow, with a purple spot at the base of 

 each petal, finally turning red. This is the species which is 

 generally cultivated in the West Indies, and forms a consider- 

 able branch of their exports. The seeds are sown in rows about 

 5 feet asunder, at the end of September or the beginning of 

 October ; at first but slightly covered, but after it is grown up 

 the root is well moulded. The soil should not be stiff nor 

 shallow, as this plant has a tap root. The ground is hoed fre- 

 quently, and kept very clean about the young plants until they 

 rise to a moderate height. It grows from 4 to 6 feet high, and 

 produces two crops annually ; the first is eight months from the 

 time of sowing the seed ; the second within four months after 

 the first, and the produce of each plant is reckoned about one 

 pound weight. The branches are pruned and trimmed after the 

 first gathering ; and if the growth is over luxuriant, this should 

 be done sooner. When great part of the pods are expanded, the 

 wool is picked and afterwards cleared from the seeds by a 

 machine, called a gin, composed of two or three smooth wooden 

 rollers of about one inch diameter, ranged horizontally, close, 

 and parallel to each other, in a frame ; at each extremity they 

 are toothed or channelled longitudinally, corresponding one with 

 the other ; and the central roller being moved with a treadle or 

 foot-lathe, resembling that of a knife-grinder, makes the other 

 two revolve in contrary directions. The cotton is laid in small 

 quantities at a time upon these rollers whilst they are in motion, 

 and readily passes between them, drops into a sack, placed un- 

 derneath to receive it, leaving the seeds which are too large to 

 pass with it, behind. The cotton thus separated from the seeds 

 is afterwards hand-picked and cleansed thoroughly from any 

 little particles of the pods or other substances, which may be ad- 

 hering to it. It is then stowed in large bags, where it is well 

 trod down, that it may be close and compact ; and the better to 

 answer this purpose, some water is every now and then sprinkled 

 on the outside of the bag ; the marketable weight of which is

 produce two hundred and forty pounds to that quantity, or two 

 hundred and seventy pounds on an average. Long's jam. iii. p.

N. B. There are 29 species described by Von Rohr, which 

 are probably varieties or synonymous with those described above. 

 There are 7 species described by Paris, which are also probably 

 synonymous with those above. 



Cult. The shrubby species may be increased by seeds, 

 or cuttings not too much ripened will root freely under a hand- 

 glass in a light soil. The annual and biennial species should be 

 sown in pots in spring, and placed in a hot-bed frame, and when 

 the plants are of sufficient size they should be planted in separate 

 pots and shifted into larger ones as they grow. A light rich soil 

 suits them best. The species require a moist heat.
