The boys pulled strongly but without jerking. The raft slanted and Anne made a grab at the pile of clothes in the middle. Dick fell off into the water again.

He climbed back, spluttering. “Have to pull more smoothly,” he said. “I felt the sack give a bit, didn’t you?”

Julian nodded. He was shivering with cold, but his eyes were shining with excitement. Anne put a macintosh round his shoulders and one round Dick’s too. They never even noticed!

“Now - pull again,” said Julian. “Steady does it - steady - steady! It’s coming! Gosh, it’s really coming. Pull, Dick, pull!”

As the heavy bag came up on the end of the rope, the raft slanted again, and the boys pushed themselves back to the other side of the raft, afraid of upsetting everyone into the water. Timmy began to bark excitedly.

“Be quiet, Timmy,” said George at once. She knew how easily sound travels over water, and she was afraid the couple in the tents might hear him.

“It’s coming - it’s there, look - just below the surface!” said Anne. “One more pull, boys!”

But it was impossible to pull the heavy bag on board without upsetting the raft, As it was, the girls got very wet when the water splashed over the raft as it jerked and slanted.

“Look - let’s paddle back to the shore and let the sack drag behind us.” said Julian, at last. “We shall only upset the raft. Dress again, Dick, and we’ll get back to the old house and open the sack in comfort. I’m so cold now that I can hardly feel my fingers.”

The boys dressed as quickly as they could, They were shivering, and were very glad to take up their paddles and work hard to get the raft back to shore. They soon felt a welcome warmth stealing through their bodies, and in ten minutes had stopped shivering. They felt very pleased with themselves indeed.

They looked back at the bulky object following them, dragging along just under the surface. What was in that bag? Excitement crept over all of them again, and the paddles struck through the water at top speed as all the four strained to get back as quickly as possible. Timmy felt the excitement too, and wagged his long tail without ceasing as he stood in the middle of the raft, watching the thing that bobbed along behind them.

They came at last to the end of the lake. Making as little noise as possible they dragged the raft under its usual bush. They did not want to leave it out on the bank in case Maggie and Dirty Dick saw that it had been used again, and started wondering.

Dick and Julian dragged the waterproof sack out of the water. They carried it between them as they went cautiously back to the house. It looked a most miserable, grotesque place with its burnt-out roof, doorways and windows - but the children didn’t notice its forlorn appearance in the moonlight - they were far too excited!
