The leaves of the trees have so vulgar a contrast in the black of stems, branches, and twigs, that they are from the first obviously not the leaves of the woods. They are all the better admired by many eyes, for whom the modest contrasts of nature are not enough; and you may hear the black and green of the parks praised for this same immoderate effect of colour. But the grass has nothing to tell that tale of the London winter which the branch tells; it is this year's; it has no past; it is innocent, and answerable to the sun for merely its few inches of simple green. It might be supposed to have the graces of an alien in London. But it has them not at all; it comes up a Londoner. You cannot be really intimate with it; and when it puts up its little flower, and your child brings it home to you hot from a clenched hand, even then it has nothing, nothing whatever, of the fields. You put it into water to flatter the child, but even there, given by that little alien hand, and so isolated from its park and its railings, it is unmistakably the grass of its own soil; it manifestly could never have been romping with little young dandelions on the side of a village road, or tossed by visiting winds scented with meadows. The London spring is a good thing, but it is another thing. It is only because of the accident by which the real spring and the London spring appear at the same time of the year that they have come to bear the same name, and even to be confused together by the insensitive. A handful from the hedgerows twenty miles away--a handful, already half faded, of mingled things at random, grass and herbs, not free from traces of white and warm rustic dust--an authentic little heap from the real spring, would show at once to all apprehensive eyes what the difference really is. And yet there must be careless or worldly birds that do not know it. Otherwise we should not hear such songs from the remotest river-sides sung within Kensington Gardens. Let no one pretend, however, that the bees are deceived or indifferent.
