have liked some weeks of thought. The dog, too. Just as there is only one

He lay back and fanned himself.

Then he pulled two pennies from his pocket and gave them to Gregory, and
told him to go to the station bookstall and bring back the _Exchange_ and

magic-lanterns for sale, and cameras for sale, and bicycles for sale, and
guinea-pigs for sale,--all at a bargain,--and it tells you also who wants
to buy rabbits and cameras and guinea-pigs; and it also tells you who wants
to exchange rabbits for a gun, or a dog for a fishing-rod, or a gramophone
