tallic cartridges and numerous attempts have
been made, with varying success, to render
cartridges waterproof, without impairing their
efficiency OF sensibility.
Intimately concerned also with military
affairs il the invention Of magneto-eectric tel
egraph, which ia now in extensive use in the
army for field purposes and which is an inn
provement of the greatest practical Importance.
Mr.. Holloway says:
"This Is signal triumph in elecromechancs, for By the
motive power Of small misunderstanding machine, occupying
less than cubic foot dial index telegraph Is operated
through great distances. from FIVE 10 two bundled miles with
the prospect greater and indefinite ertendOn II found
with the Atlantic telegraph in 1885, that alternating or tosnd

machine of the telegraph before has the pc

noca telegraph adapted with equal facility to domestic and
public purposes much that the days Of tel
egsphing the gavsnc battery numbered and that the
magnetic electric machine will long take its place Tor tins
as well Is for many other purposes"
If this machine POSSESSED no ether value, the
fact that it protects the dispatches which it sends
over the wire from being read at any nterlnedi-
ate point of their passage, would make 1t ndis-
pensable for military uses. No one knows how
many well laid plans have been brought to
confusion by the treachery of the ordinary
Geographic wires
Not to 90 particularly into other inventions,
the actual condition Of those arts which seek
protection by patents may be judged from the
statement that notwithstanding the absorption
and, alas, the destructiOn--of so much talent
and energy by the war; and Notwithstanding
the exclusion from the account OF all the States
in rebellion, the applications for patents during
the last year have been equaled only in two
years preceding. The loss, or failure to increase,
from the former of these two causes, heavily
outweighs that from the latter, for 1T Is
well known that the number of patents granted
to natives or residents of Southern States has
always been small. =" 1t appears" says the
summary before us, " that in the year 1857
there were granted to citizens Of Massachusetts
i2l patents, being a proportion of ! to a popu-
laton OF 1902. In the same year there were
granted to citizens of Virginia s. patents, pro-
portion of to 2i,5ll; to North Carolina IA
patents, proportion Of to 62,064; and to-
South Carolina II, proportion Of to 55,70o! "
If we take Massachusetts and South Carolina
as the representatives Of the two social systems
the civilized and the -barbarouS-we find
in the former that one out of 1892 Of her popu-
laton produced an invention useful to the
world; in the latter one out Of 80, zoo, and II
inventions all told. Is there anybody who does
not now understand that this il the difference
between Slavery and Freedom between con-
diiion Of society in which labor is honorable,
and a condition in which it is deemed degrad-
