TOBACCO.— II. (p. 156). 
The Plant-— The Root is large, long, and fibrous. The Stem 
is upright, tall, round, and branching near the top. The Leaves are 
large, pointed, and hairy. The Seeds are very small and plentiful. 
How Grown. — The tobacco plant is raised from seed, but, 
after the first cutting, crops may be gathered from ratoons. The 
plants take very much plant-food from the soil. They grow best in 
a light soil, which has plenty of decayed leaves and plants in it. 
The caterpillar of a large moth feeds on the leaves and spoils them, 
if not sought for and killed. 
The Crop. — The leaves are cut when ripe. Then they are 
dried, and afterwards cured. 
THE CASTOE-OIL PLANT (p. 159). 
The Plant grows to a bush or small tree. Its handsome 
leaves have from seven to eleven lobes. Three-cornered husks 
contain the seeds of the plants, which grow so fast that on some of 
them the seeds are ready when the plant is about four months old. 
The Seeds are prized for the oil they contain. 
This is drawn from them in two ways : 
(1) By boiling the crushed seeds in water; then the oil floats to the 
top. 
(2) By squeezing the oil out by machines which press and crush 
the beans. This is the better way. 
The Oil is used : 
(1) As medicine. 
(2) For burning in lamps. 
(3) For oiling machines. 
(4) lu making soap. 
YAMS, COCOES, AND SWEET POTATOES.— I. & II. (p. 161). 
Yams. — The chief kinds are : 
(1) The white; ) , a ^ a 
(2) The negro- } heart-shaped leaves and very 
(3) The afou or yellow; ) ^^^^^ 
(4) The Indian; with leaves in three leaflets, and with small 
round tubers. 
Yam plants are reared by putting into the ground the head that 
has been cut away from the tubers. This head sends out several 
young shoots, which may be cut away and planted out.
