OLD TIN CANS.
The Way They Finally Disappear From
Human Siuht,

Human Sight.
Few people reHlizo what becomes Of
all the Old tin cams, tin pans. kettles,
buckets, coal hods and the like. They
finally disappear from human sight
and knowledge and are seen no more.
Science shows that they eyapOrate.
When a tin can is cast away and for
saken it begins its downward course
by becoming rusty. The tin oxidizes or.
in other words, unites with the oxygen
surrounding it in the atmosphere. and
the oxide Of tin gradually takes leave
of the iron by evapOrating into the air,
while some OF 1t is washed away by
the rain into the earth. After the tin
is gone the iron of the can follows the
same course that has been pursued by
the tin. 1t oxidiZes and becomes the
familiar reddish brown substance
known as iron rust. The metals have
no wills of their own, no affinties. no
understandings. and therefore no in
tentions as to their present or future
course. They do nothing of them
selves But electrical forces do their
work for them. These forces unite the
atoms of the metals with those of the
oxygen. Then the molecules of these
oxides are carried away by the atmos-
pheric electricity and disposed of &C

where they are as much at home as
salt. All metals can exist in a state
Of vapor; therefore they are to be
found not only in the atmosphere
around this earth. but also in the at
mospLere around the sun and the
stars. If ray OF sunlight is bent out

are formed also among the coors and
these lines represent shadows cast by
elemental substances in the atmos-
pheres of the earth and the sun. Light
