The children remarked the suddenness of nightfall, for indeed there had been little or no twilight. This convinced me that we must be not far from the equator, for twilight results from the refraction of the sun's rays: the more obliquely these rays fall, the farther does the partial light extend; while the more perpendicularly they strike the earth, the longer do they continue their undiminished force, until, when the sun sinks, they totally disappear, thus producing sudden darkness.
CHAPTER II
THE FIRST EXPLORING EXPEDITION
We should have been badly off without the shelter of our tent, for the night proved as cold as the day had been hot, but we managed to sleep comfortably, everyone being thoroughly fatigued by the labors of the day. The voice of our vigilant cock, which, as he loudly saluted the rising moon, was the last sound I heard at night, roused me at daybreak, and I then awoke my wife, that in the quiet interval while yet our children slept, we might take counsel together on our situation and prospects. It was plain to both of us that, in the first place, we should ascertain if possible the fate of our late companions, and then examine into the nature and resources of the country on which we were stranded.
We therefore came to the resolution that, as soon as we had breakfasted, Fritz and I should start on an expedition with these objects in view, while my wife remained near our landing-place with the three younger boys.
"Rouse up, rouse up, my boys," cried I, awakening the children cheerfully. "Come and help your mother to get breakfast ready."
"As to that," said she smiling, "we can but set on the pot, and boil some more soup!"
"Why, you forget Jack's fine lobster!" replied I. "What has become of it, Jack?"
"It has been safe in this hole in the rock all night, father. You see, I thought, as the dogs seem to like good things, they might take a fancy to that, as well as to the agouti."
