The truth of this last remark was so self-evident and incontrovertible that it elicited no reply, and the three friends rode on for a considerable time in silence.

It was now past noon, and they were thinking of calling a halt for a short rest to the horses and a pipe to themselves, when Joe was heard to give vent to one of those peculiar hisses that always accompanied either a surprise or a caution.  In the present case it indicated both.

“What now, Joe?”

“Injuns!” ejaculated Joe.

“Eh! fat you say?  Ou is dey?”

Crusoe at this moment uttered a low growl.  Ever since the day he had been partially roasted he had maintained a rooted antipathy to Red-men.  Joe immediately dismounted, and placing his ear to the ground listened intently.  It is a curious fact that by placing the ear close to the ground sounds can be heard distinctly which could not be heard at all if the listener were to maintain an erect position.

“They’re arter the buffalo,” said Joe, rising, “an’ I think it’s likely they’re a band o’ Pawnees.  Listen an’ ye’ll hear their shouts quite plain.”

Dick and Henri immediately lay down and placed their ears to the ground.

“Now, me hear noting,” said Henri, jumping up, “but me ear is like me eyes—­ver’ short-sighted.”

“I do hear something,” said Dick as he got up, “but the beating o’ my own heart makes row enough to spoil my hearin’.”

Joe Blunt smiled.  “Ah! lad, ye’re young, an’ yer blood’s too hot yet; but bide a bit—­you’ll cool down soon.  I wos like you once.  Now, lads, what think ye we should do?”

“You know best, Joe.”

“Oui, nodoubtedly.’

“Then wot I advise is that we gallop to the broken sand hillocks ye see yonder, get behind them, an’ take a peep at the Redskins.  If they are Pawnees, we’ll go up to them at once; if not, we’ll hold a council o’ war on the spot.”

Having arranged this, they mounted and hastened towards the hillocks in question, which they reached after ten minutes’ gallop at full stretch.  The sandy mounds afforded them concealment, and enabled them to watch the proceedings of the savages in the plain below.  The scene was the most curious and exciting that can be conceived.  The centre of the plain before them was crowded with hundreds of buffaloes, which were dashing about in the most frantic state of alarm.  To whatever point they galloped they were met by yelling savages on horseback, who could not have been fewer in numbers than a thousand, all being armed with lance, bow, and quiver, and mounted on active little horses.  The Indians had completely surrounded the herd of buffaloes, and were now advancing steadily towards them, gradually narrowing the circle, and whenever the terrified animals endeavoured to break through the line, they rushed to that particular spot in a body, and scared them back again into the centre.
