How Mechanical Ingenuity Yokes Itself
with the Theories Of the pedants In
the Effort to Achieve New
Wonders of Invention.
Rushing through the air at the rate
of 200 miles an hour on an airship pro-
PEELED by rapid explosions of nitro
gelatine Is the proposition made by Dr. |
Edwin Pynchon, NJ. D., of Chicago. He |
is the author of paper published In
TRANSPORTATION on High explosives as
a means of propulsion in aerial naviga-
ton" In the course of his discussion
he says: "In aerial travel, the great
desideratum is ceaseless and rapid on
ward motion, and at an altitude of
from 500 to 1000 feet the best results
should be attained. 1t is quite prob
able that q speed of $50 or 200 miles an
hour can be easily had, and will, in
fact, be necessary in order to insure
commercial success. l have estimated,
with q ship of the size mentioned, that
after a full speed Of 200 miles an hour
has been attained, 1t can be maintained
by the explosion every five seconds of
a pair of 60 per cent. nitro-gelatine
cartridges, each weighing two ounces.
There will thus be required about 100
pounds of the explosive for each 100
miles of the journey, and the cost, in
cluding very liberal allowance for
construction and insulation of the cart
| ridges, should not exceed 40 cents per
| pound. The expense would then be
$1.2O per minute, or $72 per hour, being
| less than 40 cents per mile Travelled.
| Three thousand pounds of fuel would
thus more than provide for transat-
lantic voyage, and the cost thereof
should not exceed $1,000, which would
would be inexpensive for a vessel of its
| probable carrying capacity, which, in
addition to fuel and supplies, should
easily transport 25 adults, consisting of
q crew of 10 and Is passengers. Let
man but partially succeed in the field
of aerial navigation, and there Is no
doubt but that the maximum of success
will follow in much less time than has
been required in the evolution of the
ocean steamer"
In the neighborhood of 200 delegates.
representing II states and territories,
Canada and Mexico, were present at
the third national Irrigation congress,
recently in session at Denver. Colo

half the area under successful irriga-

rado, $50, 1888; Montana, 35O,5S2; Utah

The French admiralty recently con
structed an aluminium torpedo boat
which, upon trial, gave great satisfac
tion. The material of which the hull o
this boat is constructed is not pur,
aluminium, but is san alloy consisting o
"a per cent. of aluminium and per cent
of copper. The adoption of this lighte
material enabled important changes t
be made In the general designs as com
pared with the usual methods of con
stuction; but the total weight of tn
5 hull Is only about one-half of what
steel hull would be. The boat is 60 fee
