Without replying, Sam followed Robin, but the next ridge revealed nothing more hopeful. Indeed the prospect thence was, if possible, more depressing, for it was seen that the island was small, that 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.

Here supreme astonishment was the chief ingredient in their feelings, for they stood on the edge of a slope, at the foot of which, as in a basin, lay what seemed to be a small cultivated garden in the midst of a miniature valley covered with trees and shrubs, through which a tiny rivulet ran. This verdant little gem was so hemmed in by hills that it could not be seen from the sea or any low part of the island. But what surprised the discoverers most was the sight of an old woman, bent nearly double, who was busily at work in the garden. Not far from her was an old man, who, from his motions while at work, appeared to be blind. Their costume being nondescript, besides ragged, did not betoken their nationality.

Sam and Robin glanced at each other in silence, then turned to have another gaze at the scene.

“We’ve found,” said Sam, slowly and impressively, “a robber’s nest!”

“D’you think so, Sam?”

“Think so! I’m sure of it. Just think. There is nothing on such an island as this to attract any one at all—much less robbers or pirates—except the fact that it is unattractive, and, apparently, far removed from the haunts of honest men. Depend upon it, Robin, that the pirates whom we saw have made this their head-quarters and place of deposit for their booty—their bank as it were, for it’s too small for their home; besides, if it were such, we should see a colony of women and children. No—this is the great Pirate Bank of the Southern Seas, and yonder we behold the secretary and cashier!”

“And what,” said Robin with a laugh, “if there should be a few clerks in the bank? We might perhaps find them troublesome fellows to deal with.”

“We might, Robin. Would it not be wise to return and let Slagg and Stumps know what we have discovered, and take counsel together before we act.”
