n be instilled only by the teacher himself, and no
amount of laying out courses on paper and giving directions, however
valuable they may be, can possibly take the place of an able, devoted,
enthusiastic teacher. Chemistry deals with things, and hence is always
best taught in the laboratory. The classroom and the library should
create interest and enthusiasm for further laboratory work, and in
turn the laboratory work should yield results that will finally
manifest themselves in the form of good written reports.

=The teacher must continue his researches=

Original work should always be carried on by the college teacher. If
he fails in this, his teaching will soon be dead. There will always be
some bright students who can help him in his research work. These
should be led on and developed along lines of original thought. From
this source there will always spring live workers in the arts and
industries as well as in academic lines. Lack of facilities and time
is often pleaded by the college teacher as an excuse for not doing
original work. There is no doubt that such facilities are often very
meager. Nevertheless, the enthusiastic teacher is bound to find the
time and also the means for doing some original work. A great deal
cannot be expected of him as a rule because of his pedagogical duties,
but a certain amount of productive work is absolutely essential to any
live college teacher.

=Future of chemistry in the college curriculum=

The importance of chemistry in daily life and in the industries has
been increasing and is bound to continue to increase. For this reason
the subject is destined to take a more important place in the college
curriculum. If well taught, college chemistry will not only widen the
horizon of the student, but it will also afford him both manual
training and mental drill and culture of the highest order.

THE TEACHING OF PHYSICS

The need of giving to physics a prominent place in the college
curriculum of the twentieth century is quite universally admitted. If,
as an eminent medical authority maintains, no man can be said to be
educated who has not the knowledge of trigonometry, how much more true
is this statement with reference to physics? The five human senses are
not more varied in scope than are the five great domains of this
science. In the study of heat, sound, and light we may
