"Yes," replied Jonas. "But there is one thing you can do--I did not think of it before. There is a good large box in the barn, and I can put some shelves into it, and make the cover into a door; and if you want to collect a museum, you can do it in that. You can keep it out in the play room, and so it will not trouble any body in the house." Jonas meant, by _the play room_, a pretty large room, in the barn, made originally for a sort of granary, but which the children were accustomed to use for a play room. Rollo was very much pleased with this plan. He determined to collect a museum, and to put his hornets' nest in it for the first thing. As soon as he got home, as he found that dinner was not quite ready, he and Jonas went out into the barn to look at the box. It was a large box, which had been made to pack up a bureau in, so that the bureau should not get injured in the wagon which it was brought home in. As it happened, the box was smooth inside and out, and the cover of it was made of two boards, which Jonas had taken off carefully, when he took the bureau out, and had then tacked them on again; thinking that he might perhaps want it some time or other,--box, covers, and all. Now it happened, as it generally does to persons who take care of things, that the article which Jonas thus preserved, came into use exactly. The box, he said, would be just the thing. He showed Rollo how he could place it so that it would make a convenient sort of cabinet. "I can put it upon its end," said he, "and then I can put on the two cover boards with hinges,--one pair of hinges on each side; then the covers will make little doors, and it will open like a book case, only it will not be quite so elegant." "I think it will be very elegant indeed," said Rollo; "and you can make it for us this afternoon." "No," said Jonas; "not this afternoon." "Why not?" said Rollo. "O, I must attend to my work in the meadow." "O, no," said Rollo. "I mean to ask my father to let you make it this afternoon." "No; I'd rather you wouldn't," said Jonas. "Why not?" asked Rollo. "I know he will let you." "Yes, I suppose he would let me, if you were to ask him; but that would spoil the museum." "Spoil it?" said Rollo. "Yes," said Jonas. "The way to spoil any pleasure is to neglect duty for the sake of it. Work first, and play afterwards. That's the rule." "Well, but, Jonas, we want to begin our museum this afternoon." "Very well," said Jonas; "you may begin collecting your curiosities, you know; and you can put them all in a safe place, and have them all ready to put in when I get the case made." Rollo did not quite like this plan; but he knew that Jonas was always firm when it was a question of right and wrong, and so he said no more; only, after a moment's pause, he asked Jonas when he _would_ make the cabinet. "The first rainy day," replied Jonas.
