On the afternoon of the following day the two-horse wagon, surmounted by the hay-rack, went into the barn again and again with its fragrant burden; but at last Amy was aroused from her book by a heavy vibration of thunder. Going to a window facing the west, she saw a threatening cloud that every moment loomed vaster and darker. The great vapory heads, tipped with light, towered rapidly, until at last the sun passed into a sudden eclipse that was so deep as to create almost a twilight. As the cloud approached, there was a low, distant, continuous sound, quite distinct from nearer and heavier peals, which after brief and briefer intervals followed the lightning gleams athwart the gloom. She saw that the hay-makers were gathering the last of the clover, and raking, pitching, and loading with eager haste, their forms looking almost shadowy in the distance and the dim light. Their task was nearly completed, and the horses' heads were turned barnward, when a flash of blinding intensity came, with an instantaneous crash, that roared away to the eastward with deep reverberations. Amy shuddered, and covered her face with her hands. When she looked again, the clover-field and all that it contained seemed annihilated. The air was thick with dust, straws, twigs, and foliage torn away, and the gust passed over the house with a howl of fury scarcely less appalling than the thunder-peal had been. Trembling, and almost faint with fear, sho strained her eyes toward the point where she had last seen Webb loading the hay-rack. The murky obscurity lightened up a little, and in a moment or two she saw him whipping the horses into a gallop. The doors of the barn stood open, and the rest of the workers had taken a cross-cut toward it, while Mr. Clifford was on the piazza, shouting for them to hurry. Great drops splashed against the window-panes, and the heavy, monotonous sound of the coming torrent seemed to approach like the rush of a locomotive. Webb, with the last load, is wheeling to the entrance of the barn. A second later, and the horses' feet resound on the planks of the floor. Then all is hidden, and the rain pours against the window like a cataract. In swift alternation of feeling she clapped her hands in applause, and ran down to meet Mr. Clifford, who, with much effort, was shutting the door against the gale. When he turned he rubbed his hands and laughed as he said, "Well, I never saw Webb chased so sharply by a thunder-shower before; but he won the race, and the clover's safe." The storm soon thundered away to parts unknown, the setting sun spanning its retreating murkiness with a magnificent bow; long before the rain ceased the birds were exulting in jubilant chorus, and the air grew still and deliciously cool and fragrant. When at last the full moon rose over the Beacon Mountains there was not a cloud above the horizon, and Nature, in all her shower-gemmed and June-clad loveliness, was like a radiant beauty lost in revery.
