-hi IL II. MoOTt, WIZ LOT lnTSe
years was science teacher at the
Dewey, and who is now at the head
of the science work in the Seattle
high school, has discovered an en-
tirely new method of teaching the
properties and characteristics of all
kinds of waves. The Seattle Post
lntelligencer in recent issue gives
the following explanations:
THE theory has existed for some
time that light came TO the eye, heat
10 the body, i'll the form Of waves in
the ether, which are thrown off in
rings from the producing body" said
Prof. Moore. "While this explana-
ton has almost been proved by scien.
lists, nevertheless they have arrived
at their conclusion by such intricate
methods of theory ard logic that in
structors have always found this part
of physics difficult to explain to stu
dents. Prof. MOore's system is in
tended TO remove this difficulty. The
apparatus consists OF projection
lantern, galvanized iron tank with
several inches of water III it, and a
large screen. With this apparatus
all wave motion is verified before
ones eyes. Mr.. Moore first sets up
the lantern, and in front of it places
the tank, and next the screen. BY
tapping the side Of the tank he por
trays on the ocreen the simple water
waves, and by tapping two adjacent
sides he demonstrates the principal
that waves from different directions
have no effect on each other. BY in
serting n convex object in the water
he gets convex waves on the screen,
and with a concaVe object obtains
concave ones The apparatus is in
use throughout the physics depart
ment of the high school. 1t has
greatly aided students in understand
ing the principals of reflection, diff
action and refracton. 1t is used to
illustrate wave lengths of one two
hundred thousandth of an inch, and
is a great help in explaining the
principals Of images, color, sound
pitch and Interference
MIR, Moore's many friends here will
be glad to learn of his success in the
west.
Mr. Shong has written an article

ton. Under the heading of "lhe
Good Things for May" that paper
says in it's April issue, "Our leading
article will be by Prin. A. Shong
of the Nelson Dewey high school,
Superior, on the Neglect of Wiscou-
sin and Local History in Our Schools
Mr. Shong makes n strong plea for
more attention to our home history
ough investigation of the subject in
this state. He strikes vital point.n
Miss Mccormick is n regular con
tributor to the Wisconsin Journal Of
Education. In the April issue she
has two articles on the following
subjects, "Use of Pictures in Schools"
and "Seasonable Questions.
