A strange and oppressive silence seemed to have come over the whole city; not so much a silence, perhaps, as an unusual muffling of all the ordinary sounds of traffic and activity. The swish of the sleet against the window was almost continuous, but when it ceased for a moment there was heard no rattle of the streets, no rumble of the horse-cars, no clatter of trains on the elevated railroad. Instead of these familiar sounds, a wide, deep, and ominous murmur filled the air. This was not a loud and heavy sound, like the roar of the ocean, nor yet shrill, like the rush and whistling of a gale, but had a peculiar low and muffled quality that made a weird accompaniment to the dramatic situation of the artist and sitter in the storm-and-serpent-beleaguered studio. There was a horrible fascination in watching the movements of the snakes as they restlessly glided from one part of the studio to another, the scales on their thick repulsive bodies glistening in the strong light, and flashing a variety of colors. The stove was now red-hot, and the fire was roaring loudly. In spite of the intense cold outside, the heat became oppressive at the height where they sat, and Miss Van Hoorn, whose nerves were much shaken by her fright, and kept in a flutter by the movements of the snakes below, began to feel faint. The house-servants had standing orders never to interrupt the sittings on any excuse until the artist rang for luncheon. It was now half-past eleven, and Seymour, despairing of the return of the maid, at last resolved to shout as loudly as possible, and to stop the servant from opening the door by calling out to him as he came along the passageway. He explained this plan to Miss Van Hoorn, and proceeded to shout and halloo with the full strength of his lungs. He waited a few moments, but no sound of footsteps was heard, and then he shouted again and again. Still the roaring of the fire, the grumble of the storm, and the hideous rustling of the snakes alone greeted their eager ears. At last he was obliged to conclude that the noise of the storm prevented his cries from reaching the house. What to do next he did not know, but as he was fanning Miss Van Hoorn with a letter out of his pocket--indeed, with one of her own notes to him--he struck upon a plan of letting in air, and at the same time attracting the attention of some one. When the brief faint turn had passed off, he climbed down to the shelf, gathered up his tubes of color, and returned to his perch. After a few vigorous throws with the heaviest tubes, he succeeded in breaking one of the panes of the large window, and a fierce gust of wind blew upon them. To their great disappointment the opening in the glass disclosed only the blank wall of the opposite extension; and as he had wasted all his heavy ammunition, he could not break another pane higher up in the window. He tried shouting again, but with no result.
