Stern could easily have poked his pistol muzzle through the crack in the wall and shot down many of them. For an instant the temptation lay strong upon him to get rid of at least a dozen or a score; but prudence restrained his hand.
"No use!" he told himself. "Nothing to be gained by that. But, once I get my proper chance at them--!"
And again, striving to observe them with the cool and calculating eye of science, he studied the shifting, confused picture out there before him.
Then he realized that the feature which, above all else, struck him as ghastly and unnatural, was the color of the Things.
"Not black, not even brown," said he. "I thought so, last night, but daylight corrects the impression. Not red, either, or copper-colored. What color, then? For Heaven's sake, what?"
He could hardly name it. Through the fog, it struck him as a dull slate-gray, almost a blue. He recalled that once he had seen a child's modeling-clay, much-used and very dirty, of the same shade, which certainly had no designation in the chromatic scale. Some of the Things were darker, some a trifle lighter--these, no doubt, the younger ones--but they all partook of this same characteristic tint. And the skin, moreover, looked dull and sickly, rather mottled and wholly repulsive, very like that of a Mexican dog.
Like that dog's hide, too, it was sparsely overgrown with whitish bristles. Here or there, on the bodies of some of the larger Things, bulbous warts had formed, somewhat like those on a toad's back; and on these warts the bristles clustered thickly. Stern saw the hair, on the neck of one of these creatures, crawl and rise like a jackal's, as a neighbor jostled him; and from the Thing's throat issued a clicking grunt of purely animal resentment.
