Psral and his assistants having carefully
guarded its secrets Storage batteries and
dynamos Of the latest pattern were i'm
ported from Paris and put into the hull, and
probably supply the motive power. En-
Zlish air-pumps and air compressors were
likewise imported and put into position
When the boat asceEds, its pumps can be, ,
heard forcing water out OF its interior,
from which it is easy 10 infer that, Ike
other submarine boats, the Peral has metal
yater-chaubers connected with its pumps.
The last trial occurred on Dec. II, 1859,
aud lasted from $50 a. N. to 5:45, nine
hours and a quarter. During this period IL
made the following record:
/. On the surface IL displayed speed
varying from seven TO twelve miles an
hour.
Q. When submerged it displayed speed
varying from six to eleven miles an
hour.
8. At full speed it turned in ten lengths;
at half speed in five lengths, and when
slowed down in to two leDgths.
T. It submerged itself in thirty, thirty
five and forty secondA
s. It remained below the water thirty
two minutes invisible and untraceable, dur
ing which time it assembled and descended,
turned, went at full speed, backed and re-
NAMED motionless at the will of Pera.
g. 1t remained sealed six hours above and
below the surface, showing that If neces-
sary it could stay below thewater for that
length Of time.
z. At the distance of mile it was impos-
sible 70 distinguish the tower when the body
OF the boat was submerged.
s. IL rose TO the surface in half
minute from depth of thirty feet.
While the inventor professed himself as
more than satisfied with the trial trip, he
announced that there were a number OF
points il which he could make improve
msnts upon the vessel. One of these was
increase in the speei; a second was an in
crease in theAmount Of compressed air car
ried and Of tna power Of the air-compres-
sors. and third was an improvement in
the optical facilities Of the coming tower.
Peral is still the hero of the hour. Before
the last success the government advanced
1000 - defray his expenses private citi-
zens added S23, 600 MORE and one ardent
patriot in Buenos .Ayres sent him the hand
some sum of $l00,000 for the same purpose.
If it were necessary he could now obtain a
concession of 81. OOO, 600 from the state and
twice as much more from his fellow
colntrymen. The effect of Perais inven-
ton upon foreign nations has been
more than noteworthy. Naval engineers,
constructors. mechanics, machinists, officers
and scientists from England, France. Ger
many, Russia, Italy. Austria. Portugal,
Turkey, Denmark, Holland, and even little
Greece, are as thick here as brigadiers were
in Washington during the war. 1t is ex-
pected that another trial trip will be had in
the latter part Of April this year.
