The fascinating interest Of the an
Client ruins in Rhodesia, South Africa,
drew the attention Of the psychologists
OF the British Association during its
recent meeting at Cape Town. Among
these ruins the most conspicuous is the
great Zimbabwe temple, which lies
about 200 miles inland from the Indian
Ocean. The oldest Of the ruined build
ings are believed to date back at least
to the days of King Solomon. It is
thought that they were constructed by
Semitic colonists, whose chief object
was gold-mining, and who have left
indications of their worship OF Baal and
Ashtaroth, as described in the Bible.
Experts believe that precious metal to
the value of three or four hundred mil
lion dollars must have been extracted
from the gold reefs of Rhodesia in an

value Of the fiber derived from 1t. The

the ground, where they take root This
process occurs when a plant is about 6
years old, but II the leaves are taken

A late French writer has shown that
it's usefulness has been greatly exag-
gerated. 1t affects only wills too weak
to be aided, and 1t can have no value
in systematic education. Grasset has
concluded that 1t is SO often harmful
that 1t should be employed only by
the practised physician. The same
authority has found that suggestion
may not be expected to cure purely
mental state, nor even grave and
profound nervous state, nor even a
profound nervous disease like hysteria,
and that its chief value In therapeutics
is In localizing nervous disorders, espe-
cially hysteria.
