IL 1850 Mr.. Farsdav discovered tbs;
iwo pieces o. 10. piscei IN contact frure
together almos; Instantly. Mr.. Tyn-
dali says: "Dne hot summer day en-
tered q shop on the Strand. oathe sin

basin. The traiesman gave me per-
mission 10 take the pieces %. lce in NV

To IL. The thermometer wasth.n ssxiy
degrees. and ye, all The pieces were
frozen together" In this way Mr..
Tyndall formed \ chain Of ice. This
experiment NAV be made even in hos
water. Throw w. pieces of ice in n
pail full Of almost boiling water. keep
them in contact and they viii freeze to-
ge,her despite the high temperature
Mr.. Faradsy made another experiment
of the same sort. tie threw into = yes
sci full OF water several small pieces Of
ice. They ioated on the surface Of the
water. The moment one piece touched
another there was an instantaneous re-
freezing. Attraction o brought all
the pieces In contact. 80 tina; IN an IN
slant an ice-chain was formed.

what it was, the atoms resume their

Imposition ensues. In consequence of
this property ice is endowed with sin
gular Elasticity. A rope and a Knot or

be molded. The school boy VINO ILLS

ciently hard To be a dangerous pro-
~jectile.

freeze the particles together and trans
form the snow into Ice. IL snow be
compressed in molds, ice ~statuettes may
be obtained. Fill n hollow ball with
snow. pressed in as hard as possible,
and YOU NAV obtain ice balls admirably
translucid. Nothing would be- easier
than to dine with "A service made OF
nodded snow-plates, glasses. decant-
ers. all OF snow. A gentleman IN Paris
recently served sherry wine To his
friends before a hot fire in beakers
made of snow. Snow compressed IN
this way does not melt 80 rapidly as
might be thought. Ice requires a great
deal of heat before il melts. A layer OF
ice Otter becomes a protection against
cold. II you would prevent anything
from sinking To a temperature below
t%hirty-iwo degrees during the very
severest frosts. WI know you have but
to wrap it in wet rags. The process of
freezing gives to the ~environing bodies
all the heat necessary To destroy II.
The water in the rags slowly forms
small pieces of ice on the rag, and in
the meantime disenga ,es heat. which
warns the object wrapped in the rags.
A tree wrapped in rags. or in moss
saturated with water. does not freeze
even when the thermometer is several
degrees below the freezing point. The
slOwness with which ice melts is well
know. During the winter Of $40 TIE
Car built at St Petersburg a magnificent
palace Of lice. which lasted several years.
Since then have been made Of
ice. and they have been loaded with
balls and fired. They were fired ten
times without bursting. 1t is con-
%sequently indisputablc that ice melts
slowly. and may be turned to good &C
count in the polar regions. In Siberia
the windows have panes Of ice. The
remarkable property with which par,i-
Giles of ice are endowed Of molding
themselves into different shapes by re-
freezing easily explains how glaciers
make their way through narrow gorges
and expand in valleys. The ice is
broken into fragments which refreeze
