greatest advance in the electric boat
building has been made, 1 suppose, IN
the line OF the launch. Its greatest eX-
qualification was witnessed at the chi
Cago exposition, where electric launcheS
were the most popular boats on the
lagoon. Some of these boats nave since
been shipped to Venice, and there are
now regular electric passenger boats
plying the Grand canal. John JACOB
Aston has several electric boats, not
ably the cruising launch Progressa ana
The smaller COcyra- The ProgreSso Is
The largest electric boat in America.
She is forty-six feet long and can de-
velop 2. sDeed of twelve miles an hour.
It is understood that Mr. Astor con-
templates building 2 still larger elec-
tric boat
aside from pleasure boats. the
greatest use to which electric Launches
can be put is as small boats for our
men-of-war The lines of Mr.. Astors
Cocyra were so successful that they
were adopted by the American ana
Russian naval authorities. While the

Russia, was at NEUTRALITY-SUSPICIOUS.

government had just completed for the
cruiser New York The navy depart
1nent, out of compliment to the grand
duke, presented the launch TO him and
constructed a duplicate for the New
York. It is now a feature of the Rus
sian navy. The British government
owns an electric boat which it uses as

Midway, between Sherness and Chat-
ham.
"AlI these boats get their power fror
storage batteries which are concealed
under the seats. They therefore carry
their power with them. The electricity

snventor Trouve has made an ingenious
arrangement which is a rudder, pro-
p5ller and motor combined. The motor
is situated on top of the rudder. The
propeller, connected by an endless
chain to the motor, is located in large

Electric Ships in Prospect.
It is barely possible that we may yet

ships might be worked by primary bat
ferries whose elements will be dipped
IN the salt water; the water to act as
an electrolyte. 1t would be curious if
