The Radium Liquid Air Wireless
Telegraphy lecture and experiments
given at the high school auditorium
by Prof. VIM. B Patty on last We'd
nesdsy evening was decided success
and the fair sized crowd seemed we'll
pleased and satisfied that all the DEM
OnstratiOns that had been promised
we're given. The lecturer gave very
clear explanation Of the wireless tele
graph, and those who have not had
the chance to make study Of the
matter without doubt got a very good
idea of how this marvel of the age is
explained. The samples of radium
which Prof. Patty had with him were
not OF so great interest as the spin
thari -cOpes, devices which made it
possible to zee the luminous effects
produced on q screen by the continu-
Gus bombardment of that screen by
the radium emanatiOns. OF course
this device consisted essentially OF q
microscope to magnify the spots of
light on the screen. The LIQUID air
experiments were the greatest inter-
est, but perhaps as interesting rs any
thing was the ease with which this
marvellous fluid at temperature Of
3l2 below zero was handled by the
lecturer. Rubber. flowers, berries,
alcohol. and mercury were frozen by
the liquid air, and it was noted that
after they had oeen thawed t'ey were
unchanged This was explained by
the fact that the cold Of liquid air is
absolutely dry. Prof. Patty was very
frank in his statements about these
wonderful substances. He said that
at the present % practical u>e was
being made of liquid air, and that the
value Of radium in medicine had not
yet been discovered Or proved.
The following is an extract from a
letter written by Prof. O. Q. Young
from Chicago under the date Of Mar.
18th: You will be glad to hear that
the Milbank high school was placed
upon the accredited list of the North
Central Association of Colleges and
Secondary Schools at the meeting of
the board OF inspectors today, as
am to tell you. Here's hoping that
the only changes the Milbank high
school will make from its present
state of efficiency will be in the direc-
ton of still! greater efficiency. Itw'll
be recalled that Mr.. Young was the
state inspector who visited the schools
about the holidays He reported at
that time that he would be able to
recommend the school for membership p
in this association and his recon.
| mendation has been given favorable
action by the board of inspectors.
Last Friday morning the high
| school and pupils of the 7th and 9Th
grades had the good fortune to listen
| to talks by the safe supt. of public
instruction, Mr.. C.. H. Lugg, and Pres.
+. G. Per,sho of the state college
at Brookings. Both speakers were
heard attentively by the pupils and
their suggestions ought to prove help
full to many. Supt. Lugg took occa-
sion in the course of his remarks to
explain The value of the study OF
Latin in the high school course. He
called attention to the fact that one
might have acquire d much of what is
called learning and still he short on
real education. Pres. Perisho taking
the great world war as illustrating the
effect of environment on the individu-
al urged the Importance Of taking ad.
vantage of the splendid opportunities
that are open to all. He called atten-
ton to the fact that strong purpose
| will able one person to accomplish
wonders by persistent effort. The
schools were not dismissed for the
afterr oon meeting at the opera house,
but the 9th, 7th and 9Th grades attend
ed in body in charge of their teach
ers. Some of the high school classes
reciting the last period were excused
in order that pupils and teachers
might hear part of the afternoon
| program
| Miss Vaughrjof the domestic science
| department acted as one of the judges
for the sewing exhibit of the Grant
county schools. She reported that
| some OF the work was of very high
order, and that the general excellence
OF the work indicates splendid inter-
est among the pupils.
