"Forward, my men," shouted the officer. "In an hour or two we shall be out of this ill-conditioned spot, and find rest and refreshment."

The soldiers lighted their cigars and urged on their horses, while they dealt their blows freely on the backs of the Indians to quicken their speed.

I observed a peculiar smile on the countenance of Ithulpo, as the officer spoke of soon reaching a place of rest. Our attendant had, I found, managed to distribute a supply of the highly prized cacao among his countrymen; and while their features wore a look of sullen indifference as they received the ill-merited blows, I remarked that they seemed to bear up against the fatigue better than they had before done. As the sun rose higher the heat increased, till it became almost insupportable. The officers spoke earnestly together for some time, and were evidently growing anxious as to the road we were taking. At length their voices grew louder and louder, as if disputing on the point, for there was very little semblance of discipline among them. Then they called up several of their men one after the other, but could not gain the information they required. Some of the prisoners were next brought up, but they either could not or would not say whether we were pursuing the proper course, their countenances a.s.suming an expression of the most perfect ignorance and apathy. Still we pushed on, the Spaniards trying to urge their horses still faster through the heavy sand. Before us rose a bright glittering haze, through which objects every now and then appeared seemingly in the far distance--hills, and trees, and rocks, and lakes, and streams of pure water; but as we advanced they vanished, and a few barren mounds and loose stones alone were found, while the supposed water was altogether a mocking deception. To the right hand and to the left, the same inhospitable desert seemed to stretch out far away; and we had already advanced so deeply into it, that the officers probably supposed that there would be as much risk in returning as in going on. On therefore we went, the soldiers having no mercy on the prisoners, whom they urged forward, whenever they attempted to slacken their pace, with the points of their swords, till the blood trickled in streams down the backs of these miserable beings. We were riding just behind the main body of the soldiers, followed by Ithulpo and the baggage mules. The generous, kind heart of my father was almost bursting with indignation, as he saw this piece of cruelty.

At last, as an Indian more weary than the rest sunk to the ground, and a soldier was about to plunge his sword into his body, he could restrain himself no longer.

"Hold, wretch!" he exclaimed. "Add not murder to your cruelty."

The soldier, taken by surprise, did not strike the fatal blow till his horse had carried him past the fainting Indian; but, balked of his prey, his anger was kindled against my father, and turning round, he made a cut at him with his sword. Fortunately I carried a heavy riding-whip, with which I was able to parry the blow. The man did not attempt to repeat it, for the junior officer turning round, observed the act, and called him to order; but it showed us what we were to expect if we excited the anger of our captors. I could not withstand the despairing look the poor wretch cast on us as he thought we were about to pa.s.s him and to leave him to his fate; so throwing myself from my horse, I lifted his head from the ground. My father stopped also, and so did Ithulpo.

"On, on!" shouted the rear-guard of the Spaniards. "On, or we will fire at you."

"We will follow immediately," replied my father. "On my word of honour--on the word of an Englishman."

The Spaniards had never known that word broken, so they allowed us to stop to help the Indian. One of our baggage mules was lightly laden, and in spite of the threats of the soldiers we lifted him upon it. I had, as I mentioned, filled a small spirit-flask with water, and unseen I poured a few drops down his parched throat. This much revived him, and by urging on our animals, we were soon able to overtake the already weary horses of the Spaniards.

The time for breakfast had long since pa.s.sed, but still no signs of a resting-place appeared. On the contrary, the sand became finer and deeper, and the dreary expanse before us seemed to lengthen out to the horizon. As the sun also rose higher in the sky, his un.o.bstructed rays darted down with greater force upon our heads. There had been a slight breeze in the morning, blowing fresh from over the snowy summits of the Cordilleras; but that had now died entirely away, and not a breath of air stirred the stagnant atmosphere. The heat at length became almost insupportable, while our eyes could scarcely bear the glare of the sun on the white glittering sand.

To do the Spaniards credit, they bore up bravely for a long time against the heat and thirst and fatigue which a.s.sailed them. The horses, however, which had only been scantily supplied with water the night before, began to knock up--their ears dropped, their heads hung down, and their respiration became thick and fast. Ithulpo had supplied my father and me with cacao, by chewing a piece of which occasionally, we avoided any feeling of hunger; and as we also wetted our lips, when they became parched, with the water from our flasks, we did not suffer much from thirst. Still the sensation of oppression and fatigue was very painful. We received too, ere long, a warning of what might be our fate, in the spectacle which met our sight. The sun had reached his meridian height, and was descending towards the waters of the Pacific, and still it appeared that we had made no more progress than in the morning, when we came upon the bleached bones of several mules and horses, and by their side appeared, just rising above the sand, the skeletons of three human beings. It appeared as if they had all been struck down together by the same fiery blast. The soldiers, as we pa.s.sed, turned their looks aside, without uttering a word, each one feeling that he might shortly become like those ghastly remnants of mortality. I observed that the heads of the animals were all turned towards the south, by which I judged that thus they had probably travelled over a greater distance of the burning desert than we had yet pa.s.sed, so that we were yet not half over our difficulties.

"Those skeletons show that we are on the high road across the desert," I remarked to my father.

"I am afraid not, David," he answered. "They may have lost their way, and we have stumbled on them by chance."

Such, I at once saw, was too likely to be the case.

The gauze-like mist of which I had before spoken, now appeared to grow more dense, and to lose its transparent appearance; at the same time that the rays of the sun struck down with fiercer heat, and the atmosphere grew more stagnant and oppressive. Some of the soldiers had lighted their cigars, in the hope that the fumes of tobacco would alleviate their thirst; and as the tiny jets of smoke left their mouths, they went straight up towards the sky, not a breath existing to blow them aside. Suddenly, as I turned my head to the left, I saw what appeared to be a dark cloud rising from the earth. I pointed it out to my father. Ithulpo had at the same time observed it.

"m.u.f.fle up your heads in your ponchos, and push on for the love of life," he exclaimed. "It is the sand-drift swept before a whirlwind.

On! on! or it will overwhelm us!"

It was indeed an object to appal the stoutest heart. On it came, like a black wall, rising higher and higher, and curling over our heads, till the sky and the sun himself were obscured. The soldiers saw it and trembled, for they knew its deadly power; whole regiments had before been buried beneath that heavy canopy. Their only chance of safety, they fancied, was to gallop through it. With frantic energy they dug their spurs into the sides of their panting steeds. They no longer thought of their miserable prisoners. Without a sensation of commiseration, they left them to the dreadful fate they themselves strove to escape. Neither could we do anything for them: if we stopped, we also should lose our lives. As we followed the soldiers, we found the Indians all huddled together, with looks of despair on their countenances, watching the approach of the sand-drift. They had no prospect of extricating themselves either; for the Spaniards had not even cut the cords which bound them all together. I glanced at the black wall of sand; it was still some way off. Could I leave my fellow-creatures thus to perish horribly, without an attempt to save them? No burning thirst, thanks to Ithulpo's precautions, had yet dried up the sympathies of my heart.

"What are you going to do, David?" asked my father, as he saw me throw myself from my horse.

"To give these poor fellows a chance of life," I answered, drawing out my knife, and cutting away at their cords.

"Your mother and sisters, my lad, must not be forgotten," he muttered; "but stay, I will help you."

As he said this he set to work to release the Indians, in which we were directly joined by Ithulpo; the rear-guard, as they pa.s.sed by, bestowing many curses and threats of vengeance on our heads for our interference; but they were too anxious to save their own lives to prevent us.

Scarcely a minute was lost.

"Mount! mount! and ride on!" cried Ithulpo.

Throwing our knives to the Indians, we leaped on our horses, and again followed the direction we supposed the soldiers had taken. We had not proceeded many yards when the wall of sand seemed to wheel round like an extended line of infantry, and then to advance at double speed. To escape it by galloping from it was now hopeless; so we turned our horses' heads to face it. As we did so, a clear break appeared in one part.

"Let us make for yonder lighter spot," shouted my father.

We did so. On came the dark wall; the sand swept by us, whirling round and round our heads, blinding our eyes, and filling our ears and nostrils. It was with difficulty even that we could breathe, as with each respiration our mouths became choked with the sand. I endeavoured, as well as I was able, to keep close to my father, though for a time it was only by our voices, as we shouted to each other, that we were aware of each other's position. We did our utmost to keep our horses' heads in the direction the sand-storm came from, that we might the more speedily pa.s.s through it. They breasted it bravely, though their thick-drawn breath showed the pain they suffered; but they seemed to be as well aware as ourselves of the necessity of exertion. It was with difficulty, however, that we could even keep our seats, as, with our hats pressed over our eyes, our ponchos drawn tight around us, and our bodies bent down over their necks, we encouraged them to proceed with bit and rein. We were making all the time, in reality, but little real progress, as I soon discovered; their utmost exertion being required to lift their legs out of the sand, which was rapidly collecting round us.

On a sudden, a dark ma.s.s swept towards us. I know not how it was,--I believe I must have turned to my right,--I kept calling to my father as before; but oh, what horror--what agony seized my soul when he did not answer! and as I endeavoured to pierce the thick ma.s.s of sand which surrounded me, I could nowhere see him. I could not tell which way to turn. I felt lost and bewildered, and I believed that my last moment had arrived--a dreadful death was to be my lot. I did not regard myself; it was for my n.o.ble father I felt. "O that I could have died with him!" I thought. My brave horse, however, still exerted himself to save his own life and mine, when I had ceased to care what became of me, by continuing to lift his feet above the overwhelming sand-drifts.

My only wish was to find my father; but so completely was I bewildered that I knew not whether to turn to the right hand or to the left. His horse might have sunk down, I thought, and then in a few moments he would for ever have been covered up from mortal sight; or, overcome with fatigue and the suffocating atmosphere, he might have fallen, and been unable to regain his steed. Or happily he might have pa.s.sed through the sand-drift in safety, and have been all the time suffering with anxiety for my sake. But this hope was very transient; the predominant feeling was that my father was lost, and that I was about to share his fate. I was thus giving way to despair, when I was aware of a considerable decrease in the density of the sand-laden atmosphere; the last breath of the fierce whirlwind pa.s.sed by; the sun shone forth bright and clear, and I stood alone amid a sea of glittering sand. Oh, with what an aching anxious heart I looked around, to see if the one object I sought was visible on that dreary white expanse! Before me, there was nothing; a few mounds and rocks alone were to be seen between me and the horizon; but as I turned round just as the column of sand swept on, not thirty paces behind me, with joy such as I cannot describe, I saw my father stooping down and endeavouring to extricate his horse from the sand, which had partially covered him. I hurried towards him, and leaping to the ground, threw myself into his arms. For the moment all sensations of fatigue or thirst were forgotten in the joy of recovering him.

Knowing that my horse was strong, he had felt less anxiety on my account than I had on his. With some exertion we cleared away the sand, and once more got his horse upon his feet, though the poor animal appeared scarcely able to move, much less to bear a man of my father's weight.

We had still one flask of water untouched. We drank a little, and with a portion of the remainder washed the mouths and nostrils of our horses, and poured a few drops down their throats, still keeping a little for any further emergency. This very much revived them; and once more mounting, we endeavoured to find our way across the desert.

Since the sand-drift first overtook us, scarcely as much time had elapsed as it has occupied to read the account I have given; but so dreadful were the sensations I experienced, and so intense my anxiety, that to me it appeared an age. The heat soon became almost as great as before the storm, and the atmosphere as oppressive, warning us that, though thus far preserved, we were still placed in a position of great peril. It was now that I felt the benefit of the firm reliance in the goodness of Providence, which my father had ever inculcated, and which at this juncture supported him.

"Courage, my dear boy," he exclaimed. "G.o.d has thus far preserved us.

He will still find the means of rescuing us."

As he spoke, the dark wall of sand, which had been receding from us, after whirling in various directions, seemed to settle down in a line of undulating mounds in the distance; and on every side the horizon once more became entirely clear.

We naturally first tried to discover any traces of the Spanish cavalry; and after straining my eyes for some time, I perceived a few dark objects which seemed to be moving on towards the point which, from the position of the sun, we judged to be the north. Some other objects beyond them afforded us a fair hope of being able to find our way out of this dreadful desert. I could not doubt that what I saw were the tops of some tall trees, though at such a distance that their base was not visible; indeed my father, who agreed with me that they were trees, was of opinion that they grew on ground somewhat elevated above the sandy plain.

Towards them, therefore, we steered our course, as the Spaniards were also probably doing. Our horses, we fancied, must have seen them likewise, or their instinct told them that water was to be found in the neighbourhood. We looked round in vain for Ithulpo and the Indians.

Not a sign of them could we perceive, and it would have been madness to have attempted to search for them. Indeed, had we found them, we could have rendered them no a.s.sistance. I was in hopes, indeed, that Ithulpo, whose horse was strong, and who I suspected knew the country better than he pretended to the Spaniards, would have found some means of escaping, and of aiding his countrymen. We had, in truth, still too much to do in attempting to preserve our own lives, to allow us to think much of others. It would be a.s.suming to be above humanity, did I not confess this.

The sun was already sinking low; and should we be unable to reach the trees before dark, and be compelled to rest on the plain or wander about it all night, we could scarcely hope to survive. The ground we pa.s.sed over was as smooth as if the receding tide had just left it. Not the sign of a footstep of man or beast was to be seen, though here and there a slight rise showed that some harder substance had offered an impediment to the drifting sand. After toiling onwards for half an hour at a very slow pace, we came upon a horse's head just rising from the sand. He had died probably in attempting to extricate himself. Several heaps showed that others--human beings, too probably--also lay beneath.

They, at all events, were beyond all help. The horse I recognised, from the head-trappings, as belonging to the officer commanding the party.

We were pa.s.sing on, when we observed, a little on the right, a man extended on his back. A movement of his arm showed me that he was not dead, and that probably he was endeavouring to call our attention to himself.

"Though he is one of those who showed no pity to the poor Indians, we must try what we can do for him," said my father; and we turned our horses towards him.

As he saw us approach, he mustered all his strength and tried to rise.

"Water, water!" he muttered. "In mercy give me a drop of water!"

It was the cruel officer himself. Still he was a fellow-creature. We had a small portion of water in the flask. We might want it ourselves, but still we could not leave him thus to die. So I dismounted, and approached him with the flask, while my father held my horse, who showed signs of an eagerness to rush on to the oasis we had discovered. The officer, when he saw the flask, would have seized it, and drained off the whole of its contents; but I held it back, and pouring out a few drops in the cover, let them trickle down his throat. I thought of what Ithulpo had said of water being of more value often than gold. Truly those drops were more precious to the dying man; they had the effect of instantly reviving him. Brightness came back to his glazed eyes, his voice returned, and he was able to sit up, and even to make an attempt to rise on his feet; but to do so was more than his strength would allow.

"Give me more water or I shall die," he said as he saw me replacing the flask in my pocket. "My rascally troopers have deserted me, to try and save their own worthless lives, and I have only you foreigners to depend on."

"I cannot give you more water," I answered. "I have but a few drops left to moisten my father's and my own lips."

"O leave them for me. I will give you your liberty, I will give you all I possess in the world, for that small flask of water," he exclaimed.

"You will not require it, for beneath yonder trees, in the distance, you will find a fountain where you may drink your fill. Have mercy, stranger, have mercy!"

It was difficult to withstand the poor wretch's earnest appeal. I poured out a little more water, which he drank off at once. I then gave him a small lump of cocoa; and sc.r.a.ping up a heap of sand, I placed him leaning against it, so that he might feel any breath of air which might blow; promising faithfully to return to bring him to the oasis, if we were fortunate enough to reach it in safety.

"But the voracious condors and the lions will come and destroy me, if I remain here during the night alone," he shrieked out. "O take me with you, generous Englishman, take me with you!"

To do this was utterly impossible. My horse could scarcely carry me, much less another person in addition.

"Come, David," said my father; "you have done your utmost for this miserable man. We risk our own lives by further delay."

In spite, therefore, of the entreaties of the Spaniard, I again mounted my horse. It just then occurred to me that if he had his pistols, he might defend himself against any wild beasts. On my offering to load them for him, he told me that he had thrown them away. So I gave him one of my own, with a little ammunition, that he might reload it, if required. He seized the weapon eagerly as I presented it.
