They had been walking up hill, and had now descended a little, and had come to a seat above a waterfall in the grounds. They did not sit down--neither proposed that--but they stood a moment at this spot. The waterfall was an artificial feature in the grounds, and bore about as great a resemblance to the reality as a glass eye does to the living orb, or a drawing-room polka to the wild war-dance of a tribe of savages. The water fell smoothly and peacefully over a smooth ledge of masonry, then got up quietly and went on its way again, as if slightly ashamed of its tumble; a wild green bank sloped up toward the seat, but as the gardener had planned and made it, it was in keeping with the waterfall: there, however, the primrose showed its richly-embossed leaves and clusters of pale stars, the first love of the year. How is it that all first things are so delicate and pure? Overhanging the bank behind the seat stood what the gardener had not planted, a gigantic Scotch fir, its arms spread out hither and thither, scarred and weatherbeaten: if it had clung to a mountain-side over a raging torrent, it might have seemed the genius of the storm: even as it was, in the afternoon light of the spring day, it had a haggard, weird effect; but the pale green spines at the end of every twig, contrasting with the dark green of a former year, showed that, bare and battered as it looked, it was strong with the strength of renewed life. On the other side of the stream was a smooth green haugh; the clouds of the early part of the day had vanished, and the blue sky stretched overhead; innumerable crows flying homeward dotted it all over and patterned the azure dome. "Don't those crows flying often look like a lady's veil floating and fluttering against the blue?" said Lady Louisa. "I like to watch the flight of birds. 'Oh, had I the wings of a dove!'" "What would you do?" asked Dr. Brunton. "I should be pretty frequently absent from Birns Castle." "Should you?" "Yes, but a railway-train does equally well, only it is a fussier way of traveling than merely spreading one's wings would be. I am not at all romantic. Good-bye," she suddenly said, flinging a bright glance at him, and running down the narrow winding path that led to the side of the stream. "Oh, stay," he cried in a tone of entreaty--"stay only a moment!" But she heard as if she heard not, and running on crossed a little rustic wooden bridge below the fall, when she turned round and waved her hand to him, still standing where she had left him: then she disappeared through a gate and went up the gardens to the castle. "When or how is this to end?" he said to himself.
