its sides were so steep all round, as far as the eye could reach, that there was apparently no landing-place except at the spot where they had been driven on shore. The elevated interior seemed as barren as the circumference, and no neighbouring island was to be seen in all the wide field of vision. The only living creatures visible were innumerable sea-birds which circled round the cliffs, and which, on espying the intruders, came clamouring overhead, as if to order them angrily away.
"Having come thus far we may as well go to the top and have a look all round," said Robin, "and see—here is something like a track worn on the rock."
Sam's drooping spirits revived at once. He examined the track carefully and pronounced it a "human" track. "The sea-gulls could not make it, Robin. Goats, sheep, and cows cannot live without grass, therefore it was not made by them. A track is not usually worn on hard rock by the passage of pirates only once or twice over them. There is mystery here, Robin. Come, on!"
It will be observed that Robin's spirit was more hopeful than that of his friend, nevertheless Sam being physically more energetic, was, when not depressed, prone to take the lead. He walked smartly forward therefore, followed humbly by his friend, and they soon reached what proved to be the summit of the island.
