We go to the wood and lie down on the dried leaves from last year, and watch the flowers and talk about them and the little mice who live in the undergrowth. Sometimes, if we are not too lazy, the Elf makes us pick primroses and daffodils and violets to send to children we know in town--pale-faced children who think we must be dull in the country, with nothing to do, and no pantomimes. Really, of course, there is such a lot to do in the country that we have always got the next thing planned before we have done what we are doing. And as for pantomimes this very wood is just like a theatre, with mice and rabbits and birds for actors, and the most beautiful transformation scenes. Why, just now in Spring it is yellow with primroses and daffodils, with pale larches wearing their new green dresses. But soon all the trees will be green, and the whole wood will be carpeted in blue, deep rich blue, the colour of the wild blue-bells, whose leaves we can see coming up all over the place. Spiky green leaves they are, and the children see them at once. "Blue-bells are coming," sing the Imp and the Elf, and so they are, and with the blue-bells comes Summer. Besides the lark and cuckoo, who is going to be talked about in a minute, besides the flowers, there are other things we watch for signs of Summer, and those are the trees themselves. We watch the trees for flowers and for buds. From the high windows of the house we can see over the fields to the woods, and see them change colour from the dead bareness of Winter very early in the Spring. And when we go to the woods in daffodil time we all three of us watch the buds coming out on every branch farthest out on the lowest boughs, which for Imps and Elves are also easiest to see. Earlier than this we look for catkins on the hazel trees. The Elf calls the hazels "the little children of the wood" because they grow low, and the other trees, the oaks, and beeches, and elms, and chest-nuts, and birches, tower above them. In some parts of the country catkins are called lambstails, because they hang down just like the flabby little tails of the Spring lambs. What do you think they really are? The Elf would not believe me when I told her they were hazel flowers. "Trees don't have flowers," she said. I reminded her of hawthorns and wild roses, and she said, "Oh, yes, but these things are greeny-brown and not like flowers at all." But they _are_ flowers. They are the flowers of the hazel tree, and they are almost the very first of the Spring things that we see. If you look about when you are in the woods you will find that lots of other trees have green flowers, too, and many of them just the same shape as the lambstails.
