"Och! it's only a kaymal!" cried Old Bill, as soon as the daylight enabled him to get a fair view of the animal. "What on hearth is it doin' 'ere?" "Sure enough," suggested Terence, "it was this beast that stepped over us while we were asleep! It almost squeezed the breath out of me, for it set its hoof right upon the pit of my stomach." "The same with me," said Colin. "It sunk me down nearly a foot into the sand. Ah, we have reason to be thankful there was that drift-sand over our bodies at the time. If not, the great brute might have crushed us to death!" There was some truth in Colin's observation. But for the covering of sand,--which acted as a cushion,--and also from that which formed their couch yielding beneath them, the hoof of the great quadruped might have caused them a serious injury. As it was, none of them had received any hurt beyond the fright which the strange intruder had occasioned them. The singular incident was yet only half explained. They saw it was a camel that had disturbed their slumbers; that the animal had been on its way up the ravine,--perhaps seeking shelter from the sand-storm; but what had caused it to return so suddenly back down the slope? Above all, why had it made the downward journey in such a singular manner? Obscure as had been their view of it, they could see that it did not go on all-fours, but apparently tumbling and struggling,--its long limbs kicking about in the air, as if it was performing the descent by a series of somersaults. All this had been mysterious enough; but it was soon explained to the satisfaction of the four castaways, who, as soon as they saw the camel by the bottom of the gorge, had rushed down and surrounded it. The animal was in a recumbent position,--not as if it had lain down to rest, but in a constrained attitude, with its long neck drawn in towards its forelegs, and its head lying low and half-buried in the sand! As it was motionless when they first perceived it, they fancied it was dead,--that something had wounded it above. This would have explained the fantastic fashion in which it had returned down the slope,--as the somersaults observed might have been only a series of death struggles. On getting around it, however, they perceived that it was not only still alive, but in perfect health; and its late mysterious movements were accounted for at a single glance. A strong hair halter, firmly noosed around its head, had got caught in the bifurcation of one of its fore-hoofs, where a knot upon the rope had hindered it from slipping through the deep split. This had first caused it to trip up, and tumble head over heels,--inaugurating that series of struggles which had ended in transporting it back to the bottom of the ravine,--where it now lay with the trailing end of the long halter knotted inextricably around its legs.
