And they did go quick. They fitted up the Susquehanna for her
new destination. Her powerful machinery was brought to bear
upon the hauling-chains. The aluminum projectile only weighed
19,250 pounds, a weight very inferior to that of the transatlantic
cable which had been drawn up under similar conditions. The only
difficulty was in fishing up a cylindro-conical projectile, the
walls of which were so smooth as to offer no hold for the hooks.
On that account Engineer Murchison hastened to San Francisco,
and had some enormous grappling-irons fixed on an automatic
system, which would never let the projectile go if it once
succeeded in seizing it in its powerful claws. Diving-dresses
were also prepared, which through this impervious covering allowed
the divers to observe the bottom of the sea. He also had put on
board an apparatus of compressed air very cleverly designed.
There were perfect chambers pierced with scuttles, which, with
water let into certain compartments, could draw it down into
great depths. These apparatuses were at San Francisco, where
they had been used in the construction of a submarine breakwater;
and very fortunately it was so, for there was no time to
construct any. But in spite of the perfection of the machinery,
in spite of the ingenuity of the savants entrusted with the use
of them, the success of the operation was far from being certain.
How great were the chances against them, the projectile being
20,000 feet under the water! And if even it was brought to the
surface, how would the travelers have borne the terrible shock
which 20,000 feet of water had perhaps not sufficiently broken?
At any rate they must act quickly. J. T. Maston hurried the
workmen day and night. He was ready to don the diving-dress
himself, or try the air apparatus, in order to reconnoiter the
situation of his courageous friends.
But in spite of all the diligence displayed in preparing the
different engines, in spite of the considerable sum placed at
the disposal of the Gun Club by the Government of the Union,
five long days (five centuries!) elapsed before the preparations
were complete. During this time public opinion was excited to
the highest pitch. Telegrams were exchanged incessantly
throughout the entire world by means of wires and electric cables.
The saving of Barbicane, Nicholl, and Michel Ardan was an
international affair. Every one who had subscribed to the Gun
Club was directly interested in the welfare of the travelers.
