“Fire!” said the doctor loudly, and crackcrackcrack with measured slowness the rifles of all three rang out, to raise a fresh set of echoes, and as these were still repeating themselves another and a fiercer yell rang out, for three of the mounted men had gone down and their horses had dashed forward, charging right at the barrier, snorting and tossing their manes, but only to turn back, startled by the heap of rocks piled-up before them, and returned at a fierce gallop, to confuse the crowd they had left, when the rifles from the other side flashed out fire and white puffs of smoke, and three more of the enemy went down, to free their startled and plunging ponies from their riders’ reins.

A yell more fierce than ever arose from the little crowd of Indians, whose mounts began to partake of the excitement imparted by the ponies that had begun to tear to and fro in the narrow gulch, while after discharging another innocuous flight of arrows against the barrier of stones, about a dozen of the savages came on, yelling and belabouring their mounts, driving them nearly frantic as they urged them forward.

The riders were evidently imbued with a mad belief that their half-wild steeds would surmount the barrier by leaps and climbing, as after a short wild career they were forced right at the rugged mass of stones. Fully half breasted it, some to fall, others to wrench themselves round, while others again flung their riders, to gallop back snorting with excitement, as they returned to dash into the halting mob they had left and add fresh confusion there.

They were exciting moments at the barrier. One Indian pitched upon his head to lie senseless, but three more regained their feet, tore their knives from their belts, and placing them between their teeth to leave their hands free, began to climb up the slope of rough jagged stones to take vengeance upon the whites who had dared to oppose their attack. But not one of them reached the top of the hurled-down masses of rock, which were, after all, not half-way up to where the little party crouched, patient, cool, and watchful, as they obeyed their leader’s orders not to waste a shot.

The result of the desperate attack was that one man stopped short, tottered, and fell back, to roll over to the bottom and then begin to crawl slowly back, leaving his comrades motionless where they had fallen.

There was a few moments’ pause as the one man crept painfully back, and then about a dozen of the Indians dismounted and joined in driving the frantic ponies that were galloping about through an opening made for them by the waiting band.

This done the party remounted, and set up another furious yell to frighten the defenders from their posts.

Needless to say, this was as vain as the next and larger flight of arrows, which splintered amongst the stones or glanced off to fly far overhead.

There was no firing now by the defenders, for the need was not urgent. “Let them exhaust themselves,” cried the doctor, “and find out that their efforts are vain.”
