Teaching of Geography.
The teaching of geography in the
schools will not be revolutionized nor
materially changed by the shifting
boundary lines of European countries,
resulting from the world war and the
formation of new nations. in the opinion
of DR.. Mendel E. Branom of Harris
Teachers College, st. Louis.
The principles of geography will re- re-
main the same, regardless OF the
changes in boundaries" he said. ''The
people of the sandy plains will go right
along raising beets, the same as before
the war. The climates will not change.
The people will be the same and they
will speak the same languages. few
arbitrary boundary lines will be rear
ranged, but that will not affect the
study of peoples. resources and customs.
We now think in regions rather than
an political boundary lines"
The speaker said that originally the
singing method" was used in teach
ing geography, such as from Calais
to Dover is twenty-eight miles over
This he said was succeeded by the
descriptive method by which bounda
Jies of countries were considered
the important part of the lesson. This
in turn, he claimed. has been succeed
Ell by the interpretive styles Of
teaching.
The surprising speed in which
islands form in rivers when obstruc-
tions defect the current in the
channels was discussed by scientists
at the joint session of the Geological
Society of America and the Botanical
Society of America.
Stimulation of Production.
Results of an Investigation to de-
termine the most effective method of
stimulating production by the proper
use of the physical power of work
men were outlined today by Prof
=. S. Lee of Columbia University
New York. before the section on
physiology and experimental science
a the convention of the American
Association for Advancement of
Science here. Prof. Lee. who during
the war studied industrial conditions
abroad as a federal investigator. said
that industrial physiology is new
sc.ence, developed during the war.
J5y use of physiological rules it is
possible to determine at wha, period
IN the work day the workman is most
efficient in his duties, he said.
The old rule of industry has been
work a man to the limit and then
throw him aside. but that is not con-
sidered efficiency under present con-
ditions and methods of study, he as
serted.
Tests to Govern Plans
In studying the physical industrial
conditions to develop accurate rules
tests have been made in factories
showing the effect of holidays on en-
ployes, the effects of rest periods and
the effect of long hours on the num-
ber of accidents. he declared.
From these tests, he continued, eff
forts will be made to outline in
dustrial plans by which each line of
work may know whether the human
machine may reach it's greatest pro-
duction by working six, eight or ten
hours a day and at what period the
most efficient work can be done
Poisoned Bats for Grasshoppers"
and Organization for Grasshopper
Control were discussed by speakers
ing of the Association of Horticul-
Studies on the Effects of Arsenicai
and Other Insecticides on the Larvae
of the Oriental Peach Moth" was out
lined by Alvah Peterson of New
Brunswick. N: J..
The convention sessions will close
late today.
