Presently he observed in the extreme distance, on his right hand, a line of mountainous hills, which he supposed to be the southern shore of the Lake, and that he was sailing into a gulf or bay.

He debated with himself whether he should alter his course and work across to the mountains, or to continue to trace the shore.

Unless he did trace the shore, he could scarcely say that he had circumnavigated the Lake, as he would leave this great bay unexplored.
He continued, therefore, to sail directly south.
The wind freshened towards noon, and the canoe flew at a great pace.
Twice he passed through similar mists.

There were now no islands at all, but a line of low chalk cliffs marked the shore.

Considering that it must be deep, and safe to do so, Felix bore in closer to look at the land.
