Now that people had really come at last to search the island the children were glad to carry out their plans, for the days of waiting had been very upsetting. They had laid their plans so well that everything went like clockwork. Daisy, the cow, did not seem a bit surprised to have Jack leading her to the inner cave again, and went like a lamb, without a single moo!

Jack got her safely through the narrow passage to the inner cave and left her there munching a turnip whilst he went to see if he could help the others. Before he left the outer cave he carefully rubbed away any traces of Daisy’s hoofmarks. He arranged the bracken carelessly over the entrance so that it did not seem as if anyone went in and out of it.

Mike arrived with the hens just then, and Jack gave him a hand. Mike squeezed himself into the little tiny cave that led by the low passage to the inner cave, for it had been arranged that only Jack and the cow should use the other entrance for fear that much use of it should show too plainly that people went in and out.

Jack passed him the sack of hens, and Mike crawled on hands and knees through the low passage and into the big inner cave where Daisy was. The hens did not like being pulled through the tiny passage and squawked dismally. But when Mike shook them out of the sack, and scattered grain for them to eat, they were quite happy again. Jack had lighted the lantern in the inner cave, and it cast its dim light down. Mike thought he had better stay in the cave, in case the hens found their way out again.

So he sat down, his heart thumping, and waited for the others. One by one they came, carrying odds and ends. Each child had done his or her job, and with scarlet cheeks and beating hearts they sat down together in the cave and looked at one another.

“They’re not at the island yet,” said Jack. “I took a look just now. They’ve got another quarter-mile to go. Now, is there anything we can possibly have forgotten?”

The children thought hard. The boat was sunk. The cow and the hens were in. The fire was out and well scattered. The hen-yard was covered with sand and heather. The yard-fence was taken up and stored in Willow House. The seed-patches were hidden. The milk-pail was taken from the spring.

“We’ve done everything!” said Peggy.

And then Mike jumped up in a fright. “My hat!” he said. “Where is it? I haven’t got it on! I must have left it somewhere!”

The others stared at him in dismay. His hat was certainly not on his head nor was it anywhere in the cave.
