NOTICE TO INMATES
For the benefit of any inmates who appre-
ciate and see the opportunity that their spare
hours give toward means of self education
through correspondent school courses, study of
good literature, acquiring education in our
Night Schools, or, who need helpful informa-
ton in connection with their work in our var
ious departments, will herewith be privileged
to use the Query" column. You are well
come to send in any queries of serious inter.
est, to yourself, THE MIRROR with the kind
collaboration of Miss Miriam E. Carey, Su-
pervisor of Institutional Libraries, will gladly
endeavor to supply the requested information.
NOTICE-In order to regulate the conduct
register number and lock number to all queries
submitted for publication Inmates names, of
course, will not be published, only the initials
of each queriSt being used.-EditOr
O:-CD Can you inform me as to the
date of birth and birthplace of Victor
Hugo? (2) In what year did he write
"Les Miserables" Pc. De G.
A:-D Born in 1902 at Besancon,
France exact date not obtainable. (2) 1862.
OWL you tell me why the sun
seems larger in the morning than later in
the day? J.
A:-This is due to the refraction of the
suns rays through the vapors on the hori-
zon, and also to the fact that it is COM
pared at the time with visible objects on
the horizon, such as trees and houses.
Q:-Under proposed woman suffrage
amendment how old does woman have
to be before she can vote ?-D. B.
A:-She can vote at age of 81. In
England a woman must be 80 years of
age to vote.
O:-What is the name and title of the
Prince of Wales? "A. B.
A:-The name and titles of the Prince
of Wales are: His Royal Highness Prince
Edward Albert Christian George Andrew
Patrick David of Windsor, Prince of
Wales, Duke of Cornwall, Duke of Rothe-
say, Earl of Chester, Earl of Carrick,
Baron of Renfrew, Lord of the Isles and
Grand Steward or Seneschal of Scotland,

Justice of St. John of Jerusalem and THU
lar Prior of the Priory for Wales, High
Steward of Windsor, besides many mill
tary and naval titles.
OILS air as strong as steam? Is two
hundred pounds of steam equal in strength
to two hundred pounds of air?-H. S.
A-Air and steam are both gases. As
such their strength or the force with
which they expand when under compress
sion varies with the pressure. This pres
sure is measured in pounds per square
inch. They are both measured by the
same type of gauge. Steam, at 200
pounds pressure, merely means that it is
exerting pressure of 200 pounds per
square inch on all parts of the vessel con-
tanning it. The same applies to the air
when under the same pressure. Neither
the air nor steam would have any force
if carried at atmospheric pressure unless
they were acting on vacuum. The
strength of steam is derived from the
fact that its water is evaporated under
pressure. The heat required to boil the
water depends on the pressure on the
water. Thus only 212 degrees are re-
quired to boil water at 1877 pounds while
381 degrees are required for pressure of
200 pounds per square inch. In case of
the compressed air, outside force is re-
quired to compress the air.
O:-(1) Why is it that the sun is so far
north in July and so far south in January,
and why do suns rays strike northern
hemisphere perpendicularly in summer
and obliquely in winter?. (2) Why is it
that earth is 100000 miles nearer to sun
in winter than in summer? Scientists tell
us sun is stationary; I know it rotates on
its axis but has it forward movement
through space?-C. T.
A:-(1) Motions of earth will be found
fully described in any reference work or
text book. Change in height of sun at diff
ferent seasons is result of fact that earth's
axis is inclined at angle to its annual
path around sun. (2) The orbit of earth
is not an exact circle but is an ellipse or
slightly elongated circle; an ellipse has
two foci or "centers," and the sun is at
one of these. 1t happens that earth in
our northern winter is in that part of or
bit nearest to sun. The sun is far from
stationary" Nothing in universe is sta
