Then these new continents will become, in their turn, uninhabitable; heat will die away, as does the heat from a body when the soul has left it; and life will disappear from the globe, if not for ever, at least for a period.

Perhaps then, our spheroid will rest--will be left to death--to revive some day under superior conditions! But all that, my friends, is the secret of the Author of all things; and beginning by the work of the insects, I have perhaps let myself be carried too far, in investigating the secrets of the future.
"My dear Cyrus," replied Spilett, "these theories are prophecies to me, and they will be accomplished some day." "That is the secret of God," said the engineer.
"All that is well and good," then said Pencroft, who had listened with all his might, "but will you tell me, captain, if Lincoln Island has been made by your insects ?" "No," replied Harding; "it is of a purely volcanic origin." "Then it will disappear some day ?" "That is probable." "I hope we won't be here then." "No, don't be uneasy, Pencroft; we shall not be here then, as we have no wish to die here, and hope to get away some time." "In the meantime," replied Gideon Spilett, "let us establish ourselves here as if forever.

There is no use in doing things by halves." This ended the conversation.

Breakfast was finished, the exploration was continued, and the settlers arrived at the border of the marshy region.

It was a marsh of which the extent, to the rounded coast which terminated the island at the southeast, was about twenty square miles.
The soil was formed of clayey flint-earth, mingled with vegetable matter, such as the remains of rushes, reeds, grass, etc.
