“Yes, and tell them they’ll get well slapped for running off like this without finishing their work,” said his aunt in a rage.

Mike ran off, calling to his uncle that he was on an errand for his aunt. So Uncle Henry said nothing, but let him go. Mike tore across the fields to the lakeside and met the two girls there. They hugged one another in joy.

“Now, where’s Jack?” said Mike. “He said he would meet us as soon as he could.”

“There he is!” said Nora; and sure enough, there was Jack coming across the field, waving to them. He carried a heavy bag into which he had crammed all sorts of things at the very last moment - rope, an old mackintosh, two books, some newspapers, and other things. His face was shining with excitement.

“Good! You’re here!” he said.

“Yes, but we nearly couldn’t come,” said Nora, and she told Jack what had happened.

“I say! I hope this won’t mean that your uncle and aunt will start to look for you too soon,” said Jack.

"Oh no!” said Mike. “It only means that they will make up their minds to whip us well when we go back this evening, but we shan’t go back! They’ll think we’ve gone off on our usual Sunday picnic.”

“Now we’ve got a lot to do,” said Jack seriously. “This is all fun and excitement to us - but it’s work, too - and we’ve got to get on with it. First, all these things must be carried from the hollow tree to the boat. Mike, you get out some of them and give them to the girls. Then we’ll take the heavier things. I expect we shall have to come back to the tree three or four times before it’s emptied.”

The four of them set off happily, carrying as much as they could. The sun was hot, and they puffed and panted, but who cared? They were off to the secret island at last!
