But since then I have learnt that there are many, many things about which we grown people, as well as you children, may ask questions, and say, "How do they come?" and there is no answer ready for us except that old wise answer--God has made them to be. I daresay you may have a little garden of your own. Did you ever, in spring-time, make a hole in the soft brown earth, and drop into it a little black round seed? Perhaps last March you put in a good many sweet peas, and then covered each one up in its earthy bed, and left them. People told you not to forget to take care of your garden, and so you often watered the place where the seeds lay hidden, and at last you saw something very tiny, but fresh and green and full of life, where only the dark brown earth had been the day before. You clapped your hands for pleasure, and ran to tell everybody: "My sweet peas are coming up!" You see you can tell when the seeds are growing, but you cannot tell how they grow; you can water the ground where they are lying hidden from your sight, but when you have done all you know how to do, you must still leave them to God's care; for He alone can make those little dark balls spring up and grow, and blossom in sweetness and beauty. What wonderful thing it was that went on underground so quietly, while you were asleep or at play, neither you nor I can tell; and this dead-like seed coming to life and springing up into beauty is only one of the many things which go on in this world all around us, seen and known only by God, who says of the seed of His word, sown by His servants--not in the ground, but in the hearts of people--that it is He who "giveth the increase." We speak of vegetable life as well as of animal life, for I am sure you have not forgotten that plants breathe through their leaves--they drink in water by their roots, and some plants even show that they are sensitive to touch by shrinking if anything comes in contact with them; but how a daisy, with its hardy little stem and its fresh green leaves and "crimson-tipped" flower, comes to grow out of the earth, we do not know at all. The beautiful leaves, fringed with downy hairs, are the lungs of the plants; and just as the blood runs through the veins at the back of your hand, the sap: which is the life-blood of the plant, runs through some fine veins which you see at the back of the leaf. If this sap were to cease flowing up the stem, the leaves and flowers would soon droop and die. [Illustration: GREEN PASTURES.] Look at the sheep, cropping the grass so busily that they hardly lift their heads from the ground. Every time they breathe, they give out air which feeds all the green things around them; and as the green things breathe this air, by the very act they purify it, and give it back to the sheep, fit for them to inhale again.
