get a little nearer. I see I am right; there the little bird is, running rapidly up the tree; now he stops, as if examining the bark; now he is off again. How very like a mouse, to be sure! It is one of the smallest of our British birds, and, though common enough, is not very often seen, except by those who, caring for such things, use their eyes well. Now he has gone to the opposite side of the tree; off he goes again and explores another trunk. By means of its long curved claws and stiff forked tail-feathers, this prettily marked bird is enabled to climb with great rapidity. It remains in this country all the year, and is more abundant in plantations and parks where there are plenty of trees. It makes its nest in a hollow tree, or on the inner side of the bark of a decayed one. The little bird lays many eggs, from six to nine, in the month of April; they are nearly white, with a few pinkish spots, generally at the larger end of the egg. It utters a few pleasing but feeble notes. The young ones are, as you may suppose, tiny little things. You should notice the curved pointed beak of this bird, and the stiff tail-feathers it presses against the tree as a fulcrum to aid it in its ascent. [Illustration: TREE-CREEPER AND YOUNG.] We will go into this adjoining field, which will soon be ready to mow. We will keep by the hedge--for it would not be right to trample down the tall grass--and gather a few grasses. Few people know more about grass than that it is good pasturage for cattle and sheep. Let us gather a lot, and take care, as far as we can, to gather only one kind each. How graceful and beautiful they are, and what difference there is amongst them; some have a stiff spike-like head of flowers, others have pretty drooping heads; some are harsh and rough to the touch, others soft as satin. Some, again, are of great value as pasturage and for making into hay; others are positively noxious weeds. You know the twitch or couch grass, that gives the farmer so much trouble; it is most rapid in its growth and difficult to kill; its underground creeping stems spread in all directions, and, if left to itself, would soon take sole possession of the whole soil. So the farmers are very careful to rake together all they can; they then collect it in heaps and burn it. Here is the rough "cocksfoot grass," with its head or "panicle" as it is called, upright and tufted. Look at its large yellow stamens; it is a very productive species and enters largely into all hay-grass. Here is the common quaking grass, with its slender, smooth, spreading branches. See how the numerous little heads tremble with the slightest motion; we do not see much of it in these meadows. It is an exceedingly pretty grass, and often seen on the chimney-pieces of cottagers, but is by no means a valuable agricultural grass; on the contrary, it is a sign, when abundant, of poor land.
