CHAPTER V.
The island—The gigantic cockle-shell—Amongst the blacks—The Corroboree.

After getting out of the water, Mat and Tim remained stretched on the sand without moving a limb, enjoying the sense of perfect security from the sea; but at length they felt that they must commence to look for water, their thirst was so great after all the salt water that they had swallowed. On trying to rise, they found they could scarcely stand, so numbed and weary were their limbs; but by stamping and running, they caused the blood to flow through their veins, and were thus enabled to start on a small voyage of discovery.

The island, as it proved to be, consisted of large rocks full of caves with a few bushes and ferns growing here and there. There was no lack of water in the crevices of the rocks, and astringent though it was, it seemed like nectar to the thirsty lads. In one of the caves they found that the sand was deep, dry, and even warm, and in this spot they determined to take a good long rest, which they felt themselves sadly in need of. Tim had proceeded to explore one of these caves, when Mat heard him call, “Look here,” and proceeding to the spot, found his brother examining the floor of the cave, which was covered with oyster shells; a further search showed the remains of several small fires with more shells round them.

“Some one has had a good feast here, Mat; let us have a nap, and then we’ll look for oysters.”

So without more ado, they buried themselves in the sand up to their necks, and fell into a sound sleep.

How long they slept neither of them knew, but Mat was awakened by a cold feeling about his nose, and jumping up, found to his astonishment and delight, his faithful dog, which greeted him with short, sharp barks of delight; the noise woke Tim, who perceiving his favourite, seized him, and the two rolled over together with joy. They found to their surprise that Jumper’s coat was quite dry, and on emerging from the cave, perceived that whilst they had been sleeping, the storm had abated, and the sun was now shining, also that the tide had run out, leaving their island connected with the mainland by a spit of sand. The tracks of the dog plainly showed that, having landed farther down the coast, he had been trying along the edge of the water for his masters, until led to them by this streak of sand.

Congratulating themselves upon the recovery of their dog, which they had given up for lost, Mat and Tim proceeded to gather a supply of oysters—these being rock oysters were easily detached by the tap of a stone.

In the pools, left by the receding tide, amongst the rocks and coral, many kinds of fish were imprisoned, and there were quantities of crabs in a muddy belt of mangroves, so that there was no lack of food, which, however, had to be eaten raw.

“We’ve always eaten oysters raw,” quoth Mat, “and why not fish that swim?”
