## Key lines

> Presently the reporter told the sailor to wait just where he was until he should come back, and without losing a moment, he walked back along the coast in the direction which Neb had taken some hours before, and disappeared quickly around a turn in the shore.

The reporter instructed the sailor to stay put, then hurried along the coast to find Neb, vanishing around a bend.

_Gideon Spilett leaves to search for Neb._

> These lithodomes were oblong shellfish, adhering in clusters to the rocks. They belonged to that species of boring mollusk which can perforate a hole in the hardest stone, and whose shell has the peculiarity of being rounded at both ends.

The lithodomes were oblong shellfish that cluster on rocks and can bore into stone, with rounded shells.

_Herbert identifies the lithodomes as edible mollusks._

> Pencroff and Herbert went down between the rocks, into those sandy corridors, lighted only by the huge cracks between the masses of granite, some of which only kept their equilibrium by a miracle.

They entered the sandy passages among the rocks, dimly lit by gaps in the granite, some rocks balanced precariously.

_Discovery of the Chimneys as a potential shelter._

> The river shall be our road and our carrier, too. Timber-floats were not invented for nothing.

The river will serve as both a road and a carrier for transporting wood via a float.

_Pencroff plans to use the river to move firewood._
