Night had closed in, and the temperature, which had modified when the wind shifted to the northwest, again became extremely cold. Also, the sea having destroyed the partitions which Pencroft had put up in certain places in the passages, the Chimneys, on account of the draughts, had become scarcely habitable. The engineer's condition would, therefore, have been bad enough, if his companions had not carefully covered him with their coats and waist-coats.
Supper, this evening, was of course composed of the inevitable lithodomes, of which Herbert and Neb picked up a plentiful supply on the beach. However, to these molluscs, the lad added some edible sea-weed, which he gathered on high rocks, whose sides were only washed by the sea at the time of high tides. This sea-weed, which belongs to the order of Sucacae, of the genus Sargussum, produces, when dry, a gelatinous matter, rich and nutritious. The reporter and his companions, after having eaten a quantity of lithodomes, sucked the sargussum, of which the taste was very tolerable. It is used in parts of the East very considerably by the natives. "Never mind!" said the sailor, "the captain will help us soon." Meanwhile the cold became very severe, and unhappily they had no means of defending themselves from it.
The sailor, extremely vexed, tried in all sorts of ways to procure fire. Neb helped him in this work. He found some dry moss, and by striking together two pebbles he obtained some sparks, but the moss, not being inflammable enough, did not take fire, for the sparks were really only incandescent, and not at all of the same consistency as those which are emitted from flint when struck in the same manner. The experiment, therefore, did not succeed.
Pencroft, although he had no confidence in the proceeding, then tried rubbing two pieces of dry wood together, as savages do. Certainly, the movement which he and Neb gave themselves, if they had been transformed into heat, according to the new theory, would have been enough to heat the boiler of a steamer! It came to nothing. The bits of wood became hot, to be sure, but much less so than the operators themselves.
After working an hour, Pencroft, who was in a complete state of perspiration, threw down the pieces of wood in dis-
