MEANS FOR THE SCIENTIFIC DE- 
VELOPMENT OF MATHEMATICS 
TEACHERS! 
THE war just and justly closing has many 
lessons for teachers. One of these is that 
those who are best prepared intellectually and 
have a deep interest in their subject will win 
in the end. Pedagogy like militarism trains 
directly for the object, but knowledge of the 
subject like the development of the general 
resources of a country gives real power and 
endurance. I fear our schools, especially our 
universities, have lately tended towards the 
former type of training for teachers and it is 
hoped that one of the lessons of this war is 
that there is danger in this direction. Peda- 
gogy, as far as it enables the teacher to make 
students study what they do not want to study, 
is the militarism of the teaching profession. 
Among the other lessons which this war has 
taught us as teachers of mathematics is not to 
lose our confidence in the great usefulness of 
our subject. If any of us were discouraged 
during recent years by those who talked 
thoughtlessly but effectively about the useless- 
ness of algebra and geometry we doubtless 
have largely recovered from this discourage- 
ment. The courses for the Students’ Army 
Training Corps, as well as those given under 
the auspices of the Y. M. C. A. at the various 
naval stations, exhibit the extensive mathe- 
matical needs of those who aim to render the 
most efficient service under the most trying 
circumstances. Our new merchant marine 
will continue to make large demands for men 
with considerable mathematical training and 
will thus tend to emphasize the practical use- 
fulness of our subject.

Mathematics Teachers, which was to be held on 
November 8, 1918, but was postponed on account 
of the influenza epidemic.
