west rose Mount Franklin, which concealed a great part of the horizon. Herbert, from the height of his observatory, could examine all the yet unknown portion of the island which might have given shelter to the strangers whose presence they suspected.
The lad looked attentively. There was nothing in sight on the sea, not a sail, neither on the horizon nor near the island. However, as the bank of trees hid the shore, it was possible that a vessel, especially if deprived of her masts, might lie close to the land and thus be invisible.
Neither in the forests of the Far West was anything to be seen. The wood formed an impenetrable screen, measuring several square miles. It was impossible even to follow the course of the Mercy, or to ascertain in what part of the mountain it took its source. Perhaps other creeks also ran towards the west, but they could not be seen.
Yet, though all indication of an encampment escaped Herbert's sight, could he not catch some glimpse of smoke, the faintest trace of which would be easily discernible in the pure atmosphere? For an instant Herbert thought he could perceive a slight smoke in the west, but a more attentive examination showed that he was mistaken. He strained his eyes in every direction, and his sight was excellent. No, decidedly there was nothing there.
The two sportsmen returned to Granite House. There Cyrus Harding listened to the lad's account, shook his head and said nothing. It was very evident that no decided opinion could be pronounced on this question until after a complete exploration of the island.
Two days after the 28th of October—another incident occurred, for which an explanation was again required.
Whilst strolling along the shore about two miles from Granite House, Herbert and Neb were fortunate enough to capture a magnificent specimen of the order of chelonia. It was a turtle of the species Midas, the edible green turtle, so-called from the color both of its shell and fat.
Herbert saw this turtle as it was crawling among the rocks to reach the sea. "Help, Neb, help!" he cried.
Neb ran up. "What a fine animal!" said Neb; "but how are we to catch it?"
"Nothing is easier, Neb," replied Herbert. "We have
