i've right to make use Of and vend
the invention or discovery in the
United States or its territories" for
seventeen years. In the patent Office
are forty-one divisions. These are
divided into some 240 general classes.
which In turn are subdivided into
many smaller classes.
One Of the chief objects of interest
OF the visitor to the patent Office is
the collection Of models, which were
saved by the action Of congress in
1907, after 1t had ordered the super
intendent to dispose Of them for econ
Gyms sake. Many Of these are his
torically valuable, and others are
simply curiosities, legacies Of dead
hopes;. but the model rooms is one of
the sights of the capital city. Some
of the miniature appliances have
come down from the early days when
the office was part Of the department
Of state.
Women have turned their Ingenuity
to profitable labor-saving inventions
for the household, and more than g.
900 patents have been issued to them
In twenty-five years. One model in
the Office, about the size OF a large
peanut. Is for q: fy-proof cradle
simply a hinged cylinder of wire net
ting. Many patents are issued for the
use of some common material for an
unusual purpose-for instance. bot
ties, collins and telegraph poles of pa
per. Some Of the most valuable are
for the smallest sort Of devise, such
as the c%an-opener. the automatic ink
stand, the glass lemon-squeezer and
the rubber change-mat for merchants.
Electrical c~ontrivances are legion.
One of the oldest Of all patents
was obtained by an Iowan, and was
designed to be a "self-tipping hat"
Much valuable energy is utilized
in tipping the hat repeatedly" says
the inventor, land my device will re-
iieve n OF it and at once cause the
hat to be lifted from the head in a
natural manner It is a novel de-
vice, In other words, for ~effecting po-
lite s%alutations by the elevation and
rotation Of the hat on the head of the
saluting party, when said person
bows to the person saluted, the actua-
ton of the hat being produced by
mechanism within it, and without the
use Of the hands in any. manner"
Another visionary but humanitarian
soul proposed spectacles for chickens
not as an aid for poor eyesight. but
as armor against the pecks of their
barnyard companions. An ingenious
inventor suggested, too, the applica-
ton OF the principle of the weather

be built in the shape Of a cigar, and
mounted on a pivot. with vanes to
keep its head into the wind. The de-
signer added all the details. such as
flights of steps travelling ON wheels.
In the long list Of American in
ventors, however, are hundreds who
are not akin to the White knight ex-
cept In ingenuity; whose practical
and truly epoch-making discoveries
have been of the greatest value TO
all human kind. The muster roll q
such men as Eli Whitney. Elias Howe,
Arkwright, Fulton, Franklin, Ericsson
Morse, Beel, Edison, Pullman, West
inghouse, Brush, Hoe Otis, Mccormick
and others Is an honored company,
BY their discoveries they have light
ened human labor, added to the an
nual produce Of land and labor which
is a nations real wealth, and have
harnessed the natural forces to mans
use. The powers of the two faculties
by which men hold communication,
speech and hearing, have been pro.

wireless telegraphy promises results
which none can foretell.
