At first, you know, they will only play. They will roll on the soft carpets, and listen to the fountain and the birds, and wander from room to room to see new beauties everywhere; but some day a boy, full of curiosity, prying here and there into nooks and corners, will touch one of the hidden springs; a door will fly open, and one storehouse of treasures will be revealed. How he will shout, and call upon his brothers and sisters to admire with him; how they will pull out the treasures, and try to learn how to use the new and strange materials. What did my father mean this for? Why did he give that so odd a shape, or so strange a covering? And so through many questions, and many experiments, they learn at last how to use the contents of this one storehouse. But do you imagine that sensible children, after one such discovery, would rest satisfied? Of course they would explore and explore; try every panel, and press every spring, until, one by one, all the closets should be opened, and all the treasures brought out. And then how could they show their gratitude to the dear father who had taken such pains to prepare this wonderful house for them? The least they could do would be to try to use every thing for the purposes intended, and not to destroy or injure any of the precious gifts prepared so lovingly for their use. Now, God, our loving Father, has made for us, for you and for me and for little Mage and Jenny, and for all the grown people and children too, just such a house. It is this earth on which we live. You can see the blue roof, and the arched ceilings of the rooms, with their canopy of leaves and drooping boughs, and the velvet-covered floors, and the lights and birds and fountains; but do you know any of the secret closets? Have you found the key or spring of a single one, or been called by your mother or father or brother or sister to take a peep into one of them? If you have not, perhaps you would like to go with me to examine one that was opened a good many years ago, but contains such valuable things that the uses of all of them have not yet been found out, and their beauty is just beginning to be known.
