They could hardly have built their nests far from this maze of little streams, or from these narrow dykes and ditches, arched with the scented tracery of limes and willows. They needed this long, dull, chilly winter in which to gather their unsuspected fund of yearning and readiness for joy; so that when high summer comes at last they may mount with virgin confidence and ardour through these sunlit spaces, to pour their souls out at heaven's gate. At heaven's gate, but not in heaven. The sky, as these larks rise higher and higher, grows colder and thinner; if they could rise high enough, it would be a black void. All this fluid and dazzling atmosphere is but the drapery of earth; this cerulean vault is only a film round the oceans. As these choristers pass beyond the nether veils of air, the sun becomes fierce and comfortless; they freeze and are dazzled; they must hurry home again to earth if they would live. They must put fuel in their little engines: after all it was flesh and blood in them that were praising the Lord. And accordingly, down they drop to their nests and peck about, anxious and silent; but their song never comes down. Up there they leave it, in the glittering desert it once ravished, in what we call the past. They bore their glad offering to the gate and returned empty; but the gladness of it, which in their palpitation and hurry they only half guessed, passed in and is a part of heaven. In the home of all good, from which their frail souls fetched it for a moment, it is still audible for any ear that ever again can attune itself to that measure. All that was loved or beautiful at any time, or that shall be so hereafter, all that never was but that ought to have been, lives in that paradise, in the brilliant treasure-house of the gods.
