All at once, as he was riding cautiously along, his rifle slung behind him, and his head bent forward to peer into the darkness, there was a sharp flash, and what seemed to be a great star of fire struck the rock, shedding a brilliant light which revealed all around for a short distance, as if a light had suddenly appeared from an opening in the mountain; and then, close in beneath where the electric bolt had struck, he could see a knot of about a dozen Indians, who uttered a tremendous yell as they caught sight of him, making Black Boy tear off at full speed, while the next moment there was a deafening crash, and it seemed to Bart that a huge ma.s.s of the mountain-side had fallen crumbling down.

That one flash which struck the mountain seemed as if it had been the signal for the elements to commence their strife, for directly after the heavens were in a blaze. Forked lightning darted here and there; the dense clouds opened and shut, as if to reveal the wondrously vivid glories beyond, and the thunder kept up a series of deafening peals that nearly drove the little steed frantic.

As to his direction, Bart was ignorant. All he knew was that he ought to have ridden some distance farther before turning off, but that awful flash had made the cob turn and bound away at once; and as far as the rider could make out, they were going straight for the lake with the dismounted Indians running and yelling madly behind.

At least that was what he fancied, for, as he listened, all he could hear was the deafening roar of the thunder, and the sharp crackling sound of the lightning as it descended in rugged streaks, or ran along the ground, one flash showing him the lake right ahead, and enabling him to turn a little off to the left, so as to pa.s.s its end.

He knew now that the pealing thunder would effectually prevent the Indians from hearing him, but the lightning was a terrible danger when it lit up the plains; and as he peered ahead, he fully expected to see a body of hors.e.m.e.n riding to cut him off. But no; he went on through the storm at a good swinging gallop, having his steed well now in hand, a few pats on its arching neck and some encouraging words chasing away its dread of the lightning, which grew more vivid and the thunder more awful as he rode on.

After a time he heard a low rushing, murmuring sound in the intervals when the thunder was not bellowing, so that it seemed to rock the very foundations of the earth. It was a strange low murmur, that sounded like the galloping of hors.e.m.e.n at a great distance; and hearing this, Bart went off at a stretching gallop, crashing through bushes and tall fleshy plants, some of which pierced the stout leggings that he wore, giving him painful thrusts from their thorns, till, all at once, the rushing sound as of hors.e.m.e.n ceased, and he realised the fact that it was the noise of a storm of rain sweeping across the plain, borne upon the wind to fall almost in sheets of water, though he pa.s.sed quite upon its outskirts, and felt only a few heavy pattering drops.

He had pa.s.sed the end of the lake in safety, and was beginning to be hopeful that he would escape the Indians altogether, but still he could not understand how it was that the little dismounted body of men had not spread the alarm, for he knew that they must have seen him, the ball of light that struck the rock having lit up everything, and he knew that he seemed to be standing out in the middle of a regular glare of light; but after the deafening crash that followed he had heard no more--no distant shouts--no war-whoop. They would be sure to communicate with their nearest scouts, and their bodies of mounted men would have begun to scour the plain in spite of the storm; for he could not think that the Apaches, who were constantly exposed to the warfare of the elements, would be too much alarmed to attempt the pursuit.

"They would not be more cowardly than I am," he said with a half laugh, as he galloped on, with Black Boy going easily, and with a long swinging stride that carried him well over the plain, but whether into safety or danger he could not tell.

All he knew was that chance must to a great extent direct his steps, and so he galloped on with the rain left behind and a soft sweet breeze playing upon his face, the oppression of the storm seeming to pa.s.s away, while it was plain enough that the thunder and lightning were momentarily growing more distant, as if he were riding right out of it towards where the air and sky were clearer. Before long, he felt sure, the stars would be out, and he could see his way, instead of galloping on in this reckless chance manner, leaving everything to his horse.

"I can't quite understand it," said Bart; "there must have been some mistake. Of course, I see now. I was riding straight along under the mountain-side when Black Boy swerved almost right round and went off in another direction: that and the darkness threw them off the track, but they will be sure to strike my trail in the morning. Black Boy's hoof-prints will be plain enough in the soft earth where the rain has not washed them away, and they'll come on after me like a pack of hungry wolves. How I wish I knew whether I was going right! It would be so valuable now to get right away before morning."

Bart was getting well ahead, but not in the best direction. He had, however, no occasion to fear present pursuit, for the knot of dismounted Indians whom he had seen close under the rock when the lightning fell lay crushed and mangled amongst a pile of shattered rocks which the electric discharge had sent thundering down, while as Bart was cantering on, full of surmises, where not a drop of rain was falling, the storm seemed to have chosen the mountain as its gathering point, around which the lightning was playing, the thunder crashing, and the water streaming down, so that in places regular cascades swept over the sides of the rock, and tore away like little rivers over the plain.

For the time being, then, Bart had nothing to fear from these unfortunate Apaches; but, as the storm lulled, and another little body of dismounted Indians crept cautiously up to the fallen rocks, their object being to surprise the guards at the gateway, they learned from one of their dying friends of the appearance of the young chief upon his little black horse, and that he had gone right off over the plain.

The sequel to this was that the dead and dying soon were borne away, and a party was formed at daybreak to take steps that would have made Bart had he known, feel terribly uncomfortable, instead of growing hour by hour more confident and at his ease.

CHAPTER THIRTY EIGHT.

HUNTED BY INDIANS.

There's something wonderfully inspiriting in sunshine--something that makes the heart leap and the blood course through the veins, raising the spirits, and sending trouble along with darkness far away into the background.

As the sun rose, flooding the wild plains with heat, and Bart drew rein and looked about after his long night-ride to see that there was hardly a cloud in sight, and, better still, no sign of Indians, he uttered a cry of joy, and bent down and smoothed and patted his brave little steed, which had carried him so far and so well.

Then he had a good look round, to see if he could make out his position, and, after a while, came to the conclusion that he was not so very far out of his way, and that by turning off a little more to the west he would soon be in the direct route.

In patting and making much of Black Boy, Bart found that the little horse was dripping with perspiration, many, many miles running having been got over in the night; and if the journey was to be satisfactorily performed, he knew that there must be some time for rest.

With this idea, then, Bart turned a little to the east, and rode straight for a clump of trees about a couple of miles away, a spot that promised ample herbage and shade, perhaps water, while, unseen, he could keep a good look-out over the open plain.

The patch Bart reached was only of a few acres in extent, and it offered more than he had bargained for, there being a pleasantly clear pool of water in an open spot, while the gra.s.s was so tempting that he had hardly time to remove Black Boy's bit, so eager was he to begin. He was soon tethered to a stout sapling, however, feeding away to his heart's content, while, pretty well wearied out by his long night-ride, Bart sat down beneath a tree where he could have a good view of the plain over which he had ridden, and began to refresh himself, after a good draught of pure cool water, with one of the long dry strips of bison-meat that formed his store.

Nature will have her own way. Take away from her the night's rest that she has ordained for man's use and refreshment, and she is sure to try and get it back. And so it was here; for as Bart sat munching there in the delicious restfulness of his position, with the soft warm breeze just playing through the leaves, the golden sunshine raining down amongst the leaves and branches in dazzling streams, while the pleasant whirr and hum of insects was mingled with the gentle _crop, crop, crop_ of Black Boy's teeth as he feasted on the succulent growth around, all tended to produce drowsiness, and in a short time he found himself nodding.

Then he roused himself very angrily, telling himself that he must watch; and he swept the plain with his eyes. But, directly after, as he thought that he must hurry on, as it was a case of life and death, he was obliged to own that the more haste he exercised the less speed there would be, for his horse could not do the journey without food and rest.

That word rest seemed to have a strange effect upon him, and he repeated it two or three times over, his hand dropping wearily at his side as he did so, and his eyes half closing while he listened to the pleasant hum of the insects all around.

Then he started into wakefulness again, determined to watch and wait until a better time for sleep; but as he came to this determination, the sound of the insects, the soft cropping and munching noise made by Black Boy, and the pleasant breath of the morning as it came through the trees, were too sweet to be resisted, and before poor Bart could realise the fact that he was ready to doze, he was fast asleep with his head upon his breast.

The sun grew higher and hotter, and Black Boy, who did not seem to require sleep, cropped away at the gra.s.s till he had finished all that was good within his reach, after which he made a dessert of green leaves and twigs, and then, having eaten as much as he possibly could, he stood at the end of his tether, with his head hanging down as if thinking about the past night's storm or some other object of interest, ending by propping his legs out a little farther, and, imitating his master, going off fast asleep.

Then the sun grew higher still, and reached the highest point before beginning to descend, and then down, down, down, all through the hot afternoon, till its light began to grow softer and more mellow, and the shadows cast by the tree-trunks went out in a different direction to that which they had taken when Bart dropped asleep.

All at once he awoke in a fright, for something hard was thumping and pawing at his chest, and on looking up, there was Black Boy right over him, sc.r.a.ping and pawing at him as if impatient to go on.

"Why, I must have been asleep," cried Bart, catching at the horse's head-stall and thrusting him away. "Gently, old boy; your hoofs are not very soft. You hurt."

He raised himself up, stretching the while.

"How tiresome to sleep like that!" he muttered. "Why, I had not finished my breakfast, and--"

Bart said no more, but stood there motionless staring straight before him, where the plain was now ruddy and glowing with the rays of the evening sun.

For there, about a mile away, he could see a body of some twenty or thirty Indians coming over the plain at an easy rate, guided evidently by one on foot who ran before them with bended head, and Bart knew as well as if he had heard the words shouted in his ear that they were following him by his trail.

There was not a moment to lose, and with trembling hands he secured the buckles of his saddle-girths, and strapped on the various little articles that formed his luggage, slung his rifle, and then leading the cob to the other side of the patch of woodland, where he would be out of sight of the Indians, he mounted, marked a spot on the horizon which would keep him in a direct line and the woodland clump as long as possible between him and his enemies, and rode swiftly off.

The inclination was upon him to gaze back, but he knew in doing so he might swerve from the bee-line he had marked out, and he resisted the temptation, riding on as swiftly as his cob could go, and wondering all the while why it was that he had not been seen.

If he had been with the Apaches he would have ceased to wonder, for while Bart was galloping off on the other side, his well-rested and refreshed horse going faster and faster each minute as he got into swing, the Indians began to slacken their pace. There was no doubt about the trail, they knew: it led straight into the patch of woodland; and as this afforded ample cover, they might at any moment find themselves the objects of some able rifle-firing; and as they had suffered a good deal lately in their ranks, they were extra cautious.

The trail showed that only one fugitive was on the way, him of whom their dying comrade had spoken; but then the fugitive had made straight for this clump of trees, and how were they to know but that he expected to meet friends there, whose first volley would empty half the saddles of the little troop?

Indians can be brave at times, but for the most part they are cowardly and extremely cautious. Naturally enough an Indian, no matter to what tribe he belongs, has a great objection to being shot at, and a greater objection to being hit. So instead of riding boldly up, and finding out that Bart had just galloped away, the Apaches approached by means of three or four dismounted men, who crept slowly from clump of brush to patch of long gra.s.s, and so on and on, till first one and then another reached the edge of the woody place, where they rested for a time, eagerly scanning each leaf and tree-trunk for an enemy at whom to fire, or who would fire at them.

Then they crept on a little farther, and found Bart's halting-place and the feeding-ground of the horse. Then they came by degrees upon his trail through the wood, all very fresh, and still they went on cautiously, and like men to whom a false step meant a fatal bullet-wound, while all the time their companions sat there upon the plain, keen and watchful, ready for action at a moment's notice, and waiting the signal to come on.

At last this came, for the advanced dismounted scouts had traced the trail to the farther edge of the wood, and seen even the deep impression made by Bart's foot as he sprang upon his steed.

Then the mounted Apaches came on at a great rate, dashed through the wood and came up to their friends, who triumphantly pointed to the emerging trail, and on they all went once more, one man only remaining dismounted to lead the party, while the rest followed close behind.

This little piece of caution had given poor Bart two hours' start, and when the Indians came out of the wood, he had been a long time out of sight; but there was his plainly marked trail, and that they could follow, and meant to follow to the end.

CHAPTER THIRTY NINE.

THE END OF THE RACE.

Bart had the advantage of his enemies in this, that as long as he could keep well out of sight across the plains, he could go on as fast as his horse could gallop, while they had to cautiously track his every step.

Then, too, when he came to dry, rocky, or stony portions, he took advantage thereof, for he knew that his horse's hoof-prints would be indistinct, and sometimes disappear altogether. These portions of the trail gave the Apaches endless difficulty, but they kept on tracking him step by step, and one slip on the lad's part would have been fatal.

Fortune favoured him, though, and he pressed on, hitting the backward route pretty accurately, and recognising the various mountains and hills they had pa.s.sed under the Beaver's guidance; and every stride taken by the untiring little horse had its effect upon the lad, for it was one nearer to safety.

Still it was a terrible ride, for it was only after traversing some stony plain or patch of rock that he dared draw rein and take a few hours' rest, while his steed fed and recruited its energies as well.
