Their first objective was the hillock Burgoyne had previously noticed from farther along shore. It stood well above the palm tops, rising abruptly on three sides and shelving gradually towards the east. A few coco-palms grew on the southern side, but elsewhere it was covered with comparatively short grass.
Arriving at the summit, the explorers found that the island was but a mile or so broad but nearly twice that distance in length, the land on the north side forming a long tapering neck averaging but a hundred yards in width, with the whole of the neck thickly wooded. It was on this strip of land that Burgoyne, Hilda, and Minalto had come ashore.
The reef entirely surrounded the island, although there were numerous gaps affording a communication between the open sea and the lagoon. It was on the edge of one of these channels that the life-boat struck. Had she been a couple of yards more to the south'ard she might have driven ashore on the island with very little damage, or none at all had she been swept into the small harbour where Mostyn was fortunate enough to land.
As the tide was almost at its ebb all the outlying reefs were exposed, disclosing a veritable death-trap for any vessel unfortunate enough to become entangled in the intricate shoals. At high-water the reefs surrounding the smaller island that Burgoyne had previously noticed were awash, only the mere hummock crowned by three palm trees being visible.
"There's one disadvantage that this island has and which Porfirio's island hasn't," observed Burgoyne. "In calm weather a boat can land here almost anywhere. Properly we ought to maintain a look-out station on this hill, especially if the pirates do attempt to find us."
"Do you think they will?" asked Hilda.
"They may try," replied Alwyn. "That's almost a foregone conclusion. But they'll think we've tried to make Honolulu, which is the nearest known civilized town in this part of the Pacific. If so, they're right off their course."
"Why didn't we?" inquired the girl.
"Head wind and adverse current almost the whole distance," said Burgoyne laconically.
"I'm not questioning your seamanship, Mr. Burgoyne," Hilda hastened to add, imagining by the Third Officer's somewhat brusque reply that he thought she had cast aspersions upon his sound judgment.
