The botanist hesitated, and glanced round him.

“If I might make so bold, sir,” said Isaac Martin, “I would suggest that we go right up to the top o’ the mountains. There’s nothin’ like a bird’s-eye view for fillin’ the mind wi’ right notions o’ form, an’ size, an’ character.”

Following this advice, they traversed the lower ground, which was found very prolific everywhere. Then they ascended the undulating slopes of the mountain-sides until they reached the rugged and bare rocks of the higher ground.

On the way they found further and indisputable evidence of the island having been inhabited at some previous and probably long past era. Among these evidences were spear-heads, and axes of stone, and several warlike weapons.

“Hallo! here’s a circumstance,” exclaimed Martin, stopping in front of an object which lay on the ground.

On closer examination the “circumstance” turned out to be an image made of a hard and coarse red stone.

“It is evidently an idol,” said Christian; “and here are some smooth round stones, resembling those used by the Otaheitans in war.”

Not far from the spot, and in other places as they advanced, the exploring party found heaps of stone chips, as well as more images and tools.

“I’ve been thinking,” said Brown, turning for a moment to look down at the sea, which now lay spread out far below them like a blue plain, “I’ve been thinking that the proof of people having been here long ago lies not only in these stones, axes, spears, and images, but also in the fact that we find the cocoa-nut trees, bananas, plantains, breadfruit-trees, as well as yams and sweet potatoes, grow chiefly in the sunny and sheltered parts of the island, and gathered together as if they had been planted there.”

“Here’s the best proof of all,” exclaimed Martin, who had a tendency to poke about, with his long nose advanced, as if scenting out things.
