But it was necessary to bring down the remains of the balloon from the tree, to place it in security, and this was no slight task.  Neb, Herbert, and the sailor, climbing to the summit of the tree, used all their skill to disengage the now reduced balloon.

The operation lasted two hours, and then not only the case, with its valve, its springs, its brasswork, lay on the ground, but the net, that is to say a considerable quantity of ropes and cordage, and the circle and the anchor.  The case, except for the fracture, was in good condition, only the lower portion being torn.

It was a fortune which had fallen from the sky.

“All the same, captain,” said the sailor, “if we ever decide to leave the island, it won’t be in a balloon, will it?  These airboats won’t go where we want them to go, and we have had some experience in that way!  Look here, we will build a craft of some twenty tons, and then we can make a main-sail, a foresail, and a jib out of that cloth.  As to the rest of it, that will help to dress us.”

“We shall see, Pencroft,” replied Cyrus Harding; “we shall see.”

“In the meantime, we must put it in a safe place,” said Neb.

They certainly could not think of carrying this load of cloth, ropes, and cordage, to Granite House, for the weight of it was very considerable, and while waiting for a suitable vehicle in which to convey it, it was of importance that this treasure should not be left longer exposed to the mercies of the first storm.  The settlers, uniting their efforts, managed to drag it as far as the shore, where they discovered a large rocky cavity, which owing to its position could not be visited either by the wind or rain.

“We needed a locker, and now we have one,” said Pencroft; “but as we cannot lock it up, it will be prudent to hide the opening.  I don’t mean from two-legged thieves, but from those with four paws!”

At six o’clock, all was stowed away, and after having given the creek the very suitable name of “Port Balloon,” the settlers pursued their way along Claw Cape.  Pencroft and the engineer talked of the different projects which it was agreed to put into execution with the briefest possible delay.  It was necessary first of all to throw a bridge over the Mercy, so as to establish an easy communication with the south of the island; then the cart must be taken to bring back the balloon, for the canoe alone could not carry it, then they would build a decked boat, and Pencroft would rig it as a cutter, and they would be able to undertake voyages of circumnavigation round the island, etc.

In the meanwhile night came on, and it was already dark when the settlers reached Flotsam Point, where they had found the precious chest.

The distance between Flotsam Point and Granite House was another four miles, and it was midnight when, after having followed the shore to the mouth of the Mercy, the settlers arrived at the first angle formed by the Mercy.
