sewage irrigation involves no danger.
An interesting fact concerning this
system is that the sewage passes into
drains only few feet below the sur :
face as perfectly clear water, but in
this fishes thrive sn surprisingly as to
indicate some irhuence of organic
matter that filtration through the soil
has not removed
DUALITY or THE MIND The idea
is held by DR.. b W Richardson that
the two lobes of the cerebrum give
every person two distinct brains; and
that any congregation of human be
ings, large or small, must be reckonod
at twice it's individual num5er before
| its mcutal constitution and strength
can be properly appraised The two
brains are never exactly balanced.
They sometimes work together, some
times diversity, and when one is dis
ordered there may be tendencies to
insanity, with lucid intervals if the
other is sound Com 'lete change of
personality may result from weakening
the stronger or Strengthening the
weaker. A lesson of this duality of
mn1 is that education should have for
its purpose The development Of the
physical aud mental powers without
over straining IN any direction, and
the leading to mental progress in ways
OF unity and purpose toward greatness
of life and character.
THE Projected WORLD MAJ The
need of good map OF all countries on
a uniform scale is 50 generally telt that
Prof Penck great scheme for prepar
ing such work deserves hearty
support The scale selected to
00,000-is almost exactly equiva-
lent to the Ii miles to an inch of
certain British and American surveys,
and the 20 versts to an inch OF Rus
sian maps is hoped that the pro
duction of the map may be divided
among the governments and societies
of the different countries. To repre-
sent the total land surface will require
169 sheets, each sheet containing .
square between the equator and so >
aud 5 . OF latitude and TO- OF
longitude between so and the polls
The British Empire would be respon
sible for 222 sheets, Russia for 1872,
the United States for 60, France So,
Scandinavia 81, China Is and other
countries for smaller number, the
share of Belgium, Switzerland and
Greece being only one each.
WORTH MORE THAN GOLD The
curious statement was not long ago
made that palladium is the most
valuable OF any Of the metals except
platinum A recent list of current
prices in New York gives the value of
platinum as somewhat mora than half
that Of gold, with the following rates
per troy pound for metals worth more
than gold Barium, + l,492; calcium,
1880; cerium, s2,79S, chromium,
1913; didymium, 50 3577; erbium,

prices being equivalents of quotations
by the gram, it is probable that for so
large a quantity as pound if
procurable "a considerable discount
would be made
THE MosT IMPORTANT ScIENoE.-
Chemistry, it is pointed out by Par
sons journal is the branch Of natural
science that has so far proved, beyond
all comparison, the most fertile in
benefits TO ma kind. There is absC -
lutely no branch of modern science or
art which does not directly or indi
rectly owe more or less of its develop
ment to chemistry. The manufac-
turer is no less indebted to it than
the physical and the artist and the
astronomer must alike confess its
enormous practical utility. In all the
arts, whether of peace or war, the
assistance of the chemist is an absolute
necessity. In union with optics.
chemistry has bestowed sixth sense
upon hunanity by making possible
the invention and use of the spectre
scope. 1t may even be said that the
