Once or twice he heard the crackling of twigs on his left, and once he fancied that he could hear the Malays coming on behind him; but he was not sure, and he toiled on, bathed in perspiration, thinking how wonderfully still everything was out there, and how loud the rustling noise was he made with his boots in forcing his way through the scrub.

All at once, just as he was thinking what a likely place that steep stony hill-side looked for snakes, a magnificent butterfly sprang up within a yard or two of his feet, and as he stopped short, he saw it go fluttering on in a zigzag fashion, and then pounce down all at once, only a little way on before him, and right in the direction he had to go.

“I don’t see why I shouldn’t have a specimen too,” he said to himself, as, regardless of the heat, he took off his straw hat, and crept silently on with his eyes fixed upon the spot where the beautiful insect had disappeared. He was within a yard of it, with upraised hat ready to strike, when it darted up, and he made a bound forward, striking downward with his hat at the same time.

The result was unexpected. Ned’s step was on to nothing, and, letting go of his hat, he uttered a cry of horror as he felt himself falling through bushes, and then sliding along with an avalanche of stones, apparently right away into the bowels of the earth, and vainly trying to check himself by stretching out his hands.

One moment he saw the light dimmed by the green growth over the mouth of the opening, the next he was in utter darkness, and gliding down rapidly for what seemed, in his horror and confusion, a long period. Then all at once the rattling, echoing noise of falling stones ceased, and so did his progress, as he found himself, scratched and sore, lying on his side upon a heap of stones, some of which were right over his legs. It did not take him long to extricate himself, and stand upright with his hands resting on a cold rocky wall, and as he stood there in the darkness, he obeyed his first impulse, which was to shout for help. But at every cry he uttered there was so terrible a reverberation and echo, that he ceased, and began to try to climb back up the great crack to the light of day.

To his horror and despair he soon found that such a climb would be impossible in the darkness, and as a flood of terrible thoughts threatened to sweep away his reason, and he saw himself dying slowly there from starvation, it seemed to him that it was not quite so dark as he thought, and peering before him, he felt about with hand and foot, and changed his position slowly, finding that the stones beneath him were pretty level till he made one unlucky step on a loose flat piece, which began to glide rapidly down. Although he tried hard to save himself, he slipped and rolled again for some distance before he could check his way, when he sat up with his heart bounding with joy, for, about a hundred yards or so before him, he could see a rough opening laced over by branches, through which gleamed the sunlight.

And now, as he cautiously made his way toward the light, he began to realise that he was in a rough rift or chasm in the rock, whose floor descended at about the same rate as the hill-slope; and five minutes after, he forced his passage out through the bushes which choked the entrance, to hear, away on his left, a distant “cooey.”

He answered at once, and went on descending the hill, thinking how strange his adventure had been, and that after all it was only a bit of a fright, and that he had come part of the way underground, instead of above.

And now the heat of the sun reminded him that he had lost his hat, and he stopped short with the intention of going back, but another shout on his left warned him that he must proceed or he might be lost.

“And perhaps the Malays may find it,” he argued; so tying his handkerchief over his head with a great leaf inside, he trudged on, answering the “cooeys” from time to time, till he drew nearer, and at last, in obedience to a whistle, joined his uncle about the same time as Frank.
