"You two have quite outstripped me," said Elizabeth as they returned to the boat. "I'll go on with my mat after dinner, while you see what you can do to make some fishing-tackle."
"Right!" cried Tommy; "you shall have fish for supper, if you're good."
They dined on bananas and coffee, ruefully noticing that the tin of condensed milk was nearly empty. Then Mary and Tommy went up the stream to a place where they had seen a clump of canes, which would furnish any number of fishing-rods. They selected one about six feet long, and after a good deal of trouble, the wood being tough, cut it down. Tommy brought out of her pocket two or three pieces of string of unequal length and thickness, and knotted them together.
"There's our line," she said, "and it's lucky there's no one here to laugh at it."
"How can we fasten it on to the rod?" asked Mary.
Tommy proceeded to tie the string to the thinner end of the rod.
"Oh, bother!" she said, "the cane's so smooth the string slips down every time. This won't do."
"Let's make a hole in the rod, and put the string through it," suggested Mary.
"The cane is sure to split if we try to bore a hole with a knife," said Tommy. "I know! There's a sort of spike in my knife. We'll make it red-hot, and then I dare say we can bore a clean hole."
They ran back to their little camp on the beach, where Elizabeth was still at work on her mat.
"Faster now," replied Elizabeth. "I shall beat you both soon."
They told her what they had done, and Tommy thrust the spike into the fire, which they never allowed to go out. Meanwhile, Mary hunted for something that would serve as a hook. She gave a cry of delight when she discovered a strong safety-pin; and Tommy having by this time bored a hole neatly through the cane, they very soon had their rough-and-ready fishing-tackle complete. It only remained to bait the hook. They found plenty of small shellfish clinging fast to the rocks on the shore, and they prised these up with their knives, and provided themselves with a number of the little molluscs. Thus equipped, they went along the shore in search of a spot that promised success. They were both excited--and Elizabeth was so much interested in the experiment that she laid down her mat and followed her sisters. After a little time they came to an irregular line of rocks running from the base of the cliffs towards the reef on which they had nearly struck on approaching the island. They had already observed that some of the rocks always stood above water, while others were sometimes submerged. These latter were easily distinguishable by the seaweed and the limpets with which they were covered. At the present moment the tide was going down, and the girls thought that they would have a good chance of catching some of the fish that had probably come up with the tide.
