It is extensively grown in southern Europe, and may be seen in parts 
of America. The tree is very tender, being injured by a temperature 
of eight to ten degrees below freezing. In the United States) its culti¬ 
vation is limited to the southern part of Florida and the warmer parts 
of California. 
The flowers consist of a thick fleshy cylindrical or bell-shaped calyx- 
tube, with five to seven scarlet or crimson petals, and below them very 
numerous slender stamens, or pollen-bearing parts. The pistil is un¬ 
like those usually found in oranges, which have one row of carpels, or 
seed apartments. In the pomegranate it has two rows of carpels, one 
above the other. Each carpel contains numerous seeds which are 
part]y embedded in the inner surface of the calyx-tube. 
Each fruit usually attains the size of an orange. As it develops 
from the flower, the calyx-tube becomes enlarged and its wall forms the 
leathery rind, which is generally yellow with a rosy cheek. 
Tn some places the plant, is used for hedges. Also ornamental 
varieties with double flowers are grown. A kind of pomegranate pro¬ 
ducing fruit without seeds is cultivated in India and in Persia. The 
people highly prize this kind. The rind, the bark, and the outer parts of 
the root are valuable on account of the large quantity of tannin they 
contain. It is said that the finest morocco leather is tanned with the 
rind of the pomegranate. 
The most valuable product of the tree is the coat of sweet or mildly 
acid pulp, which encloses each of the many seeds in a separate apart¬ 
ment. The juice from the pulp is largely used to make cooling drinks.

I N COLORADO, Arizona, New Mexico, and Mexico, live several 
species of ants known as the honey-making ants. Like other ants, 
they live in colonies, in underground nests. 
The foraging workers obtain the honey at night from small galls 
on oak-leaves. After the other workers and the young are fed the 
honey that "is left over is communicated to a number of ants which 
simply serve as living receptacles. These live honey-hags cling to 
the roof of the nest-chamber and move very little, and in time their
