Then the engine was started up and the three lads clambered on board.
"Good bye!" they cried to the Sandersons.
"Good bye and good luck!" answered the farmer.
"Let us know how you arrive," added his daughter.

"Oh, this is simply glorious!" cried Tom.

He had his flag in one hand and his horn in the other, and Sam was similarly equipped.
"Of course you know the way, Dick," said the youngest Rover.
"Oh, yes, it's easy.

I'll simply follow the road.

But I am going up a bit," added Dick.
