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 
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. l y 
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

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 ina 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.
