Printed matter may be copied on any
paper Of any absorbent nature by dampen-
ing the surface with 9 weak solution of
acetate of iron, and pressing in an ordi-
nary copying press, Old writing may al

a weak solution of sn1phate of iron. mixed
with small solution Of sugar syrup.
A mother who feared her son might i'll
herit taste for liquors from a drinking
ancestry gave him occasionally wine in
which small doses of tartar emetsc had
been mingled. He acquired such an aver
sion for the taste Of liquors of all sorts that
he could not be induced to touch them.
She put in just enough to nauseate him.
Lumber is now being manufactured
out OF paper, any the lumber is said to be
bett er than the timber that comes from
the woods for the reason that it will not
warp crack, split Or fall off. The only
tat tory in the world where this straw lum-
Der is made is at Long island City, The
lunber is now used for ceilings and walls

q series of very careful experiments upon
dogs. He found that of twenty animals

without accident.
Lake Michigan fisherman assert that
part of the bottom of the lake is covered
With forests. This discovery was made BY
means of their nets which cannot be used
further out then 90 miles from the shore.
Trees which have been washed ashore from
this forest bore evidence of having remain
ed under water for centuries. Though
seemingly in d perfect state OF perserVhtio
at first. they soon decuyed after exposure
to the atmosphere The wood also is said
to be Of a variety entirely unknown in this
country.
Thomas A. Edison, the electrician,
claims to have discovered another Won
derful invention-thae of being able to
send messages to and from railway trains
running at high rate OF speed. 'ihe
system was practically tested on the
Staten Island Railroad, and with great
success Messages were shot from train
running 25 miles an hour to the regular
B. & o. duplex wire over 100 feet away.
The answers leaped from the wires dowr
to the roof and were received in the usual
way much to the astonishment Of those on
board the train.
Prot c. A. Young, of Princeton College,
begs artists not to paint the crescent
moon upside down as Hogarth did in one
Of his pictures, and says: 1.-The moon is
the petrified daughter of the earth, for it
is destitute of life air, and water. The sun
and moon alone of all the heavenly bodies
affect appIeciably the earth. The temper
azure on the moon is extreme In the
dark spots, under the shadow of high
ranges OF mountains, the temperature is
about 200 degrees below zero, while in
places where the sunlight strikes the heat
is about that Of boiling water The moon
is potential in tidal influence, but beyond
this has almost no effect on the earth. If
she were annihilated it would make New
York one degree colder. But, swinging
along in her present orbit, she exercises
no influence on the weather,

shoe is made of bamboo, and this material
has proved it's superiority to its riyal, paper,

square strips. Girls round these off by
running them through dies until they look
like little broom straws. These are put
in crucibles with graphite and submitted
to white heat for several hours. This
