Tim's rush had been so swift, so silent, so effectual, that he was already running beside his cycle and preparing to mount before the three men down the track, more than a quarter of a mile away, became aware that something was wrong. The first intimation was the pounding of the horses' hoofs as they took flight. They looked up to see the cause of the sudden stampede, but Tim was hidden from them by the galloping animals, which were dashing downhill at so desperate a pace that the troopers, if they waited for them, must be almost inevitably swept off the narrow track over the precipice. Though they now heard the yells of the mounted trooper above, they durst not delay, but promptly wheeled round and set off to head the race, intending to pull up as soon as the frantic beasts behind them had recovered from their fright.
Meanwhile the shouts of their comrade had brought the other men hurriedly to the mouth of the cave, which they reached just in time to see Tim disappear round a curve in the track. They plunged through the scrub, and screamed with rage when they caught sight of the crowd of horses headed by the three troopers far down the hill to their right. Men of southern blood make little attempt to control their feelings, and these Peruvians, their vision of £500 vanished, stamped and gesticulated and wept, venting bitter curses upon the hapless trooper whom Tim had felled, and who was now sitting up and dizzily feeling his chin.
It was the presence of the three men on the track that had determined Tim to ride northward. With them waiting for him, ready to shoot as he passed, or before, there would have been little chance of successfully running the gauntlet. He had not reckoned on the stampeding of the horses; nor had it occurred to him at the first moment to follow at their heels and snatch an opportunity of slipping through in the confusion. When he did think of it, he felt very much annoyed with himself for being so stupid. Not that he could have run past them: his experience on the track soon proved that the attempt would have been hopeless. Paradoxical as it may appear, this only deepened his annoyance. Three of the horses had started up instead of down the hill. The ascent being rather steep, they were more fatigued than frightened before they had run a mile. The gallop became a trot, the trot a walk, and they were making up their simple minds to stop and refresh themselves with herbage from the side of the track when a creature on two wheels came up to meddle. At the appearance of the bicycle they kicked up their heels and fled, all their terrors revived.
It was now that Tim was angry with himself. If this was the effect uphill, what would it have been in the other direction? Flying downhill after the troop, with a judicious use of his hooter he might have kept them all madly on the run, and even driven them before him into the arms of his amiable commander. It was too late now. Tim was unreasonably irritated. An older person might have consoled himself with the reflection that it is easy to be wise after the event.
He had intended, when he started from camp, to ride northward along this very track; but he wished now that he had remained at the cross-roads, even though that might have involved playing nap with Colonel Zegarra, or making himself amiable to that gentleman's lady friends. There was danger behind him; there might be still graver danger ahead. Other parties of the enemy might be coming down; perhaps the junction of the tracks was held by them. It was a good defensible position, covering any possible attack on the Inca camp by way of the eastern route. If there had been any other path home, Tim might have taken it and bolted, without any reason to feel that he was a coward. But there was none; he was compelled to follow this only track--committed to an attempt to make the round.
There was not much reason to fear pursuit. The men whom he had tricked at the cave had lost their steeds; the other three would perhaps have to ride for many a mile in the wrong direction. Like John Gilpin, they could not help it. By the time they had checked the stampeded animals and brought them up the hill, a good many miles would separate them from the quarry who had baffled them. Tim felt quite easy on that score.
He began to take a little amusement in the chase in which he was, for his own part, involuntarily engaged. The riderless horses in front of him were not at all happy. They would gallop up the steeper inclines, out-distance the strange thudding creature behind them, and when they no longer heard its snorts, slow down and begin to take things easy. But on the more level portions of the track, and the occasional downward gradients, the machine made four or five yards to their one. They had no sooner settled down into an amble than the pertinacious pursuer came panting at their heels, and taking fresh alarm, they dashed on frantically until another rise gave muscle the advantage of mechanism. So it went on for eight or ten miles, until the horses must have thought--if horses think--that they were doomed to drop at length from exhaustion, and fall a prey to the modern centaur.
But Fate, after all, was kind to them. Tim suddenly became aware of that unpleasant sensation, abominable to every cyclist, which announces a punctured tyre. There was no loud bang, like the report of a monster pop-gun, such as sometimes startles pedestrians in the street, and makes horses tremble or prance. The air was oozing gradually away; moment by moment the rear tyre became softer and slacker; and Tim had to stop at once before irreparable damage was done.
Here was a disaster, the more serious because the track was no longer flanked by a cliff on one side and a precipice on the other, but ran along the crest of an exposed ridge, from which he could see a long way before and behind and on either hand. He could see--he might also be seen. The track afforded no cover, the country at either side very little. If he wheeled the cycle to right or left in search of a sheltered nook in which to make his repairs, he would spend much time in getting there and back again. The enemy were doubtless now hot in pursuit. Missing the tracks of his wheels they would hunt for him, and here there was no cave, no waterfall, only a scattered bush or two. They would easily find him, and then!...
Tim sprang off the machine in a hurry. His only chance was to mend it on the track. He rested it against a rock, shot a glance around, then knelt to examine the tyre. Now, as every one knows, it is sometimes not easy to locate a puncture. Tim hoped that it would not be a case of immersing the tube in water, for that would involve going down to the river half a mile away. Luckily the puncture was a fairly large one, and easily seen. The outer cover of the tyre was cut through for about two inches, and the perforation had extended to the inner tube.
He opened the pouch in which he carried a few small tools and material for making temporary repairs. From it he took a phial of rubber solution, a strip of canvas, and a "gaiter"--a thickness of rubber vulcanised to two or three layers of strong canvas, shaped to the tyre, with hooks at the bottom. The first step was to repair the inner tube. This he did by smearing the cut with the solution and sticking on a rubber patch. Then he fastened the canvas by means of the solution to the inside of the outer cover, over the rent, to prevent the inner tube from being chafed by the rough edges made by the cut. The last operation was to fix the gaiter to the rim by its hooks. All this took some time. In tyre mending, as in other things, the more haste the less speed. Tim worked with deliberate care, glancing up and down the track from time to time. At last, after about half an hour's work, he straightened himself, satisfied that the tyre was good for a few hundred miles, and much relieved that he had been able to complete the repairs without interruption.
It only remained to inflate the tyre. He had just inserted the pump when a succession of faint irregular clicks fell on his ear. Turning hastily, he looked down the track. He had a good view of it for half a mile. At that distance it curved out of sight, but was visible again for a short stretch a mile lower down, and still farther in patches. The air was very clear; every tree and hillock was sharply defined in the sunlight; there was nobody in sight.
But the clicks were growing louder; they seemed to be the sounds of iron-shod hoofs upon the rocky ground. He gazed down the track, passing from patch to patch over the intervening bluffs and the stretches of rough country where it was not visible. The sounds came beyond question from his left; still he could see nobody.
Meanwhile he was pumping hard, keeping his head turned in the direction of the sounds. All at once he caught sight of six or seven dark specks moving towards him along the sunlit track. He guessed that they were about a mile away. There was just time to fill his tyre before they came up with him.
The pursuers were now hidden by a curve in the track. He pumped on; the tyre was almost fully inflated. Suddenly he heard a shout, and saw a horseman round the bend half a mile below. He instantly whipped off the pump, turned the petrol tap, and had run a yard or two with the machine when he remembered that in his haste he had left his pouch on the ground. He could not afford to lose that. Backing, he recovered it, thrust it into his pocket, and in another twenty seconds was running slowly up the hill.
Glancing over his shoulder, he saw five men galloping after him. They were no more than a quarter-mile away, shouting, urging their horses to their utmost speed, gaining on him. But the crest of the hill was near; then the track was level for a while; then had a downward incline. The engine worked well; the cycle breasted the slope, gained the flat, and sped on at forty miles an hour.
A minute after Tim topped the crest, the horsemen reached the same spot on their panting steeds. They yelled with rage and disappointment when they saw their quarry bowling along at a speed that a Pegasus might envy. One took a shot at him, but Tim, bending over the handle-bar, offered a low target, and escaped injury. In two minutes he had turned a corner and was out of sight.
