The height of an olive tree is usually 20

is exceedingly prolific under cultivation;
the fruit yields about 20 per cent of its
weight, exclusive of kernel in oil. Italy
is SAID to produce 33,000,000 and France

The busy season of farm work should by
no means be turned into a period of
! slavery and oppression. No one should

chrOnOmeter and get his right bearings.
