The advance in the price of paper
which presses hardest upon newsps-
per publishers, may be accounted for
in q measure by the varied and con-
tinued new uses to which that article
ia applied. Among the thousands of
articles Of this material, some of the
latest are car wheels, water buckets,
window shutters, boats, bath tubs,
wash basins, blankets, etc. Bat the
very latest use of this material is in
the manufacture of stoves, which is
being successfully accomplished by
German paper makers. A writer
says of this new invention, that FIRE
blazes cheerfully without inficting
the slightest damage to the paper

In the Ionian Islands, in the neigh
borhood of Argestute, water power
is utilized in peculiar manner. A
swift stream of water running through
rocky channel for short distance
into the island, suddenly sinks into
the earth, in downward course, and
goes, no one knows where. The
earth has been cleared away for
some distance down in a kind of
shaft, and the body of water being
conducted through an artificial tun-
mel, Is forced in single stream be-
meath an understood wheel. Thus
power enough has been obtained TO
drive two mills. which are now in
successful operation.
M. Pinart, French scientist, has
been working on the Pacific coast
for more than q year, gathering pre-
historic treasures from Alaska to
Panama, and it is said has already
sent over to Paris nearly shipload
of specimens. This field for explor-
alton has been considered one Of the
most important on the globe, but to
the present time no systematic effort
has been made by American scientists
to gather together the valuable treas
ures to be found along the Pacific
slope, and our country is sadly neg
Letting the treasuring up of its own
historical monuments.
A new street sweeping machine
has been invented, which promises
to greatly reduce the cost of keeping

two men and will it is claimed clean
over mile of st-aet in an hour, and
do its work thor, .hly. The dirt is
swept by revolving brushes upon
travelling canvas on which it is car

A new process for copying trac.
ings, drawings, pictures. writing, etc,
on the Photographic plan has been
recently introduced in this country
that is not only Of much valve in
many ways, but is an interesting
amusement and pastime for young
people in producing duplicate pic.
lures, portraits, DC. The process in
brief, is about as follows: The COPY
ing paper is prepared with a sensi.
tizing solution composed of IL ounces
citrate of iron and ammonia and s
ounces clean water; and also, II
ounces red prussiate of potash and 5
ounces clean water dissolve these
separately and mix them, keeping
the solution in a dark place. Apply
a coating of this to the paper with q
spor Keep this in q dark place
also until dry. Make your drawing
on thin or transparent paper or rem.
der picture to be copied transparent.
Place the drawing over the sensi.
tized sheet which has been stretched
on a smooth surface, place q glass
over the whole to keep paper down
smoothly and expose same to SUM-
light some four or FIVE minutes. This
having been done, wash the sensi-
tized sheet 10 clean water and the
result will be surprising.
