The Chief Gardener laughed.

"No, Davy, I don't believe it would," he said. "And I think the sun is the only one who could answer your question. It is a chemistry which no one of this world has been able to explain. Chemistry is a magic which you will understand by and by, and you will know then that the sun is the greatest of all chemists. Suppose we go down into your gardens and see what he is doing there."

"SOMETIMES THE GARDENER TAKES UP THE POLLEN ON A SOFT BRUSH AND LAYS IT GENTLY ON THE STIGMA OF ANOTHER ROSE"

They all went down the little steps that led to the Chief Gardener's enclosure, where Prue and Davy had their gardens, side by side with his. There just as they entered was a great mass of morning-glory vines that every morning were covered with a splendor of purple, and pink, and white, and blue, and just beyond these was a mass of dianthus pinks of every hue and shade. Bachelor-buttons, petunias, and verbenas were all there, too, besides Prue's sweet-pease by the fence, and her alyssum and mignonette. Then came Davy's things, all fresh and growing, and beyond these the Chief Gardener had ever so many things, from beets to beans, from parsley to parsnips, from carrots to corn. In one small corner by the strawberry-bed there grew a little bed of pepper plants, and near-by a row of tomatoes. The Chief Gardener stopped in the midst of all these things.

"Here is the sun's chemistry," he said. "We put some tiny bits of life in the ground. The same earth holds them, the same rain wets them, the same air is above them. Then the sun shines, and with that earth and water and air and that tiny seed, it makes something different of its own. Of one it makes a flower, of another a fruit, and of another a vegetable. Of the flowers it makes many kinds and colors—of the fruits and vegetables it makes many shapes and flavors. The sweet red strawberry and the fiery red pepper grow side by side. It makes food of the roots of the beet, and the parsnip, and carrot, and of the seed of the bean, and of the corn. It fills the mustard, and the horseradish, and the pepper, with a flavor so that we may season our meats and soups, and it gives to thyme, and marjoram, and fennel, a sweet savor that is like an odor of by-gone days. Into the flowers it pours the color and perfume that make them delicious and beautiful, and into the fruit and vegetables the starch and phosphates that make them pleasant to the taste and nourishing to our bodies. Where do all these things come from? We do not see the colors, or smell the perfumes, or taste the sweet and the sour and the bitter in the air and water, and we could not see, or smell, or taste, them in the earth. Yet they must be there, and only the sun knows just how and where to find them, and how to make the best use of them for the world's good, and comfort, and happiness. Without the sun the earth would be bare and cold, and there would be no life—at least, not such life as we know. Every breath we draw, every bite we eat, every step we take, every article of clothing we wear, comes to us through the sun."

"Papa, we can see the sun's colors," said Davy. "When it shines through the cut-glass berry-dish it makes all its colors on the table-cloth."

"So it does, Davy, I didn't remember that. A glass prism shows us all the colors in the sunlight, and these are the colors that it puts into the flowers and fruit—just how, I am afraid we shall never know, though like all great wonders, I suppose, it is really a very simple thing. When plants grow without sunlight, they grow without color, and it is the same with little boys and girls. Open air, sunlight, fresh water, and good food—these are what make plants and people strong and happy and beautiful."

And so June passed and half the year was gone. Prue and Davy were brown from working and playing out of doors, and were growing so fast that Davy said it was hard for his corn to keep up with him. They took great pride in the flowers and vegetables that came to the table from their gardens and always wanted them in separate dishes from those that came from the larger garden. When any of their friends came to dine with them, it was Prue's flowers that were to be worn and Davy's vegetables that were first to be served. By the end of June some of the early things were gone, and had been replanted. Other things had grown so big that they were beginning to crowd in their rows and beds, so that by the first of July, the little gardens that grew side by side, and could be seen like a picture through the windows where the winter gardens had been, reminding little Prue of Alice's garden in Wonderland, had become almost a wonderland jungle.
