The Projectile weighs about 20 thousand pounds, or 10 tons ?" "Correct!" "Well, a pair of these buoys when inflated can raise a weight of 30 tons." "So far so good.

As soon as they are inflated the Projectile will come up like a cork." "Can the divers readily reach such depths ?" "That remains to be seen Mr.Marston." "Captain," said Morgan, now joining the party, "you are a worthy member of our Gun Club.

You have done wonders.
