"A cloud of dust that grows and grows and grows."
"Where?"
"In the southeast."
"I can't see it and I have pretty keen eyes."
"The naked eye won't reach so far, but the dust cloud is there just the same. It's moving in a course almost parallel with us and it grows every second I look at it. It may be the dust kicked up by a band of Sioux horsemen. Take a look, Jim, and tell us what you make of it."
Boyd looked through the glasses, at first with apprehension that soon changed to satisfaction.
"The cloud of dust is growing fast, just as you told us, Will," he said, "and, while it did look for a moment or two like Indian horsemen, it isn't. It's a buffalo herd, and the tail of it runs off into the southeast, clean down under the horizon. Buffaloes move in two kinds of herds, the giant herds, and the little ones. This is a giant, and no mistake. In a few minutes you'll be able to see 'em, plain, with your own eyes."
"I kin see thar dust cloud now," exclaimed the Little Giant. "Looks ez ef they wuz cuttin' 'cross our right o' way."
They rode forward at ease and gradually a mighty cloud of dust, many miles in length and of great width, emerged from the plain, moving steadily toward the northwest. Will, with his glasses, now saw the myriads of black forms that trampled up the dusty typhoons, and was even able to discern the fierce wolves hanging on the flanks in the hope of pulling down a calf or a decrepit old bull.
