So the children descended to the main hall and marched through it, defying Lang, the second man, refusing hats and overshoes; and presently were digging blissfully in a flower-bed under the delighted directions of Schmitt. "What are these things, anyway?" demanded Scott, ramming down the moist earth around a fragile rootlet from which trailed a green leaf or two. "Dot vas a verpena, sir," explained the old gardener. "Now you shall vatch him grow." The boy remained squatting for several minutes, staring hard at the seedling. "I can't see it grow," he said to his sister, "and I'm not going to sit here all day waiting. Come on!" And he gave her a fraternal slap. Geraldine wiped her hands on her knickerbockers and started after him; and away they raced around the house, past the fountains, under trees by the coach-house, across paths and lawns and flower-beds, tearing about like a pair of demented kittens. They frisked, climbed trees, chased each other, wrestled, clutched, tumbled, got mad, made up, and finally, removing shoes and stockings, began a game of leapfrog. Horror-stricken nurses arrived bearing dry towels and footgear, and were received with fury and a volley of last year's horse-chestnuts. And when the enemy had been handsomely repulsed, the children started on a tour of exploration, picking their way with tender, naked feet to the northern hedge. Here Geraldine mounted on Scott's shoulders and drew herself up to the iron railing which ran along the top of the granite-capped wall between hedge and street; and Scott followed her, both pockets stuffed with chestnuts which he had prudently gathered in the shrubbery. In the street below there were few passers-by. Each individual wayfarer, however, received careful attention, Scott having divided the chestnuts, and the aim of both children being excellent. They had been awaiting a new victim for some time, when suddenly Geraldine pinched her brother with eager satisfaction: "Oh, Scott! there comes that boy I told you about!" "What boy?" "The one who asked me if I was too rich and proud to play with him. And that must be his sister; they look alike." "All right," said Scott; "we'll give them a volley. You take the nurse and I'll fix the boy.... Ready.... Fire!" The ambuscade was perfectly successful; the nurse halted and looked up, expressing herself definitely upon the manners and customs of the twins; the boy, who appeared to be amazingly agile, seized a swinging wistaria vine, clambered up the wall, and, clinging to the outside of the iron railing, informed Scott that he would punch his head when a pleasing opportunity presented itself. "All right," retorted Scott; "come in and do it now." "That's all very well for you to say when you know I can't climb over this railing!"
