For Stern, trying to readjust his position, laid his right hand on the wall above his head.
A little fragment of loose marble, long since ready to fall, dislodged itself and bounced with a sharp click against the steel I-beam over which they were both peeking.
The sound, perhaps, was no greater than you would make in snapping an ordinary lead-pencil in your fingers; yet on the instant three of the Things raised their bulbous and exaggerated heads in an attitude of intense, suspicious listening. Plain to see that their senses, at least, excelled those of the human being, even as a dog's might.
The individual which, alone of them all, had been standing, wheeled suddenly round and made a step or two toward the building. Both watchers saw him with terrible distinctness, there among the sumacs and birches, with the beauty of which he made a shocking contrast.
Plain now was the simian aspect, plain the sidelong and uncertain gait, bent back and crooked legs, the long, pendulous arms and dully ferocious face.
And as the Thing listened, its hair bristling, it thrust its villainous, apelike head well forward. Open fell the mouth, revealing the dog-teeth and the blue, shriveled-looking gums.
A wrinkle creased the low, dull brow. Watching with horrified fascination, Stern and Beatrice beheld--and heard--the creature sniff the air, as though taking up some scent of danger or of the hunt.
Then up came the right arm; they saw the claw-hand with a spear, poise itself a moment. From the open mouth burst with astounding force and suddenness a snarling yowl, inarticulate, shrill, horrible beyond all thinking.
An instant agitation took place all through the forest. The watchers could see only a small, fan-like space of it--and even this, only a few rods from the building--yet by the confused, vague noise that began, they knew the alarm had been given to the whole Horde.
Here, there, the cry was repeated. A shifting, moving sound began. In the visible group, the Things were getting to their handlike feet, standing unsteadily on their loose-skinned, scaly legs, gawping about them, whining and clicking with disgusting sounds.
