"But if you were away for a year difficulties might arise. It would be better for you only to determine the course of the lode, its thickness and value, to trace it as far as possible, and then hide all signs of the work, and not to make your claim until you return here."

"Very well, I will take your advice, Dias. And now about the real object of our journey."

"I have been thinking it over deeply," Dias said. "First as to mines; at present almost all the gold that is obtained is acquired by washing the sands of rivers. Here and there gold has been found in rocks, but not in sufficient quant.i.ties to make mining pay. The rivers whose sands are richest in gold are in the mountains that lie behind Lake t.i.ticaca, which lies to the south of Cuzco and on the border of Bolivia. No one doubts that in the time of the Incas there existed gold mines, and very rich ones; for if it had not been so it is impossible to account for the enormous amount of gold obtained by the Spanish conquerors, and no one doubts that they got but a small portion of the gold in existence when they arrived. It is of no use whatever for us to search the old ruins of the Incas in Cuzco, or their other great towns; all that can be found there has already been carried away.

"Now you see, senor, Huanuco, Jauja, Cuzco, and Puno all lie near the eastern range of the Andes, and when the alarm caused by the arrogant conduct of the Spaniards began, it was natural that the treasures should be sent away into the heart of those mountains. The towns on the western sides of this plateau, Challhuanca, Tanibobamba, Huancavelica, would as naturally send theirs for safety into the gorges of the western Andes, but all traditions point to the fact that this was not done by the Incas. As soon as the Spaniards arrived and struck the first blow, the great chiefs would naturally call together a band of their followers on whose fidelity they could rely, load the treasures on llamas, of which they possessed great numbers, and hurry them off to the mountains.

"It is among the mountains, therefore, that our search must be made.

All our traditions point to the fact that it was along the eastern range of the Cordilleras, and the country beyond, that by far the greater portion of the treasures were taken for concealment. At any rate, as we have but eighteen months for the search it is on that side that we must try, and ten times that length of time would be insufficient for us to do it thoroughly. As to the gold mines, it is certain that they lie in that portion of the range between Cuzco and Lake t.i.ticaca. It was near Puno, a short distance from the lake, that the Spaniards, owing to the folly of an Indian, found great treasures in a cave. They would probably have found much more had not a stream suddenly burst out which flooded the whole valley and converted it into a lake. Which do you think we had better look for first, gold mines or hidden treasures?"

"Of course that must depend on you, Dias, and how much you know about these matters. I need not say that a hidden treasure would be of vastly more use to me than the richest gold mine in the world. To obtain the gold from a mine an abundance of labour is required, besides machinery for crushing quartz and separating the gold from it. In the bed of a river, if it is rich and abounding in nuggets, three or four men, with rough machinery, could wash out a large quant.i.ty of gold in a short time, and a place of that sort would be far better than a rich mine, which could not be worked without a large amount of capital."

"I have heard tales of such places on the other side of the mountains to the south. From time to time gold-seekers have returned with as much as they could carry, but not one in a hundred of those that go ever come back; some doubtless die from hunger and hardship, but more are killed by the Indians. Most of the tribes there are extremely savage, and are constantly at war with each other, and they slay every white man who ventures into their country."

"Then is it not probable, Dias, that the gold could have come from their country?"

"Not from the plains, but from the streams running down into them; and although the Incas never attempted to subdue the tribes beyond the mountains, they may have had bodies of troops to protect the workers from incursions by these savages."

"Are there many wild beasts there?"

"In some parts of the mountains pumas and jaguars abound."

"That is not altogether satisfactory, though I should not mind if we fell in with one occasionally. But how about game, Dias?"

"The chief game are the wild vicunas, which are very numerous in some parts; but they are very shy and difficult to hunt. Deer are plentiful, and there are foxes, bears, and hogs; but the great article of food is fish. On the plains the manatee, which is very like the seal, is caught; turtles are found in great numbers, and the people make oil from their eggs; and the buffo, a sort of porpoise, also abounds. The natives do not eat these, except when very pressed for food; they catch them for the sake of their oil. There are many kinds of fish: the sunaro, which I heard an English traveller say are like the fish the English call the pike; these grow to the length of seven or eight feet.

And many smaller kinds of fish are caught by throwing the juice of the root of the barbasto into small streams. This makes the fish stupid, and they float on the surface so that they may easily be caught by hand. There are also many sorts of fruit."

"Well, then, we ought to do fairly well, Dias."

"Yes, senor; but many of these creatures are only found in the forests and in the rivers of the plains, and they are so much hunted by the savages there that they are very shy. But there are some creatures with which we certainly do not wish to meet, and unfortunately these are not uncommon. I mean the alligators and the great serpents. The natives fear the alligators much, for their weapons are of no avail against them, and they would never venture to attack a great snake."

"And besides these, what other disagreeables are there, Dias?" Bertie asked cheerfully.

"There is one other disagreeable," Dias replied, "and it is a serious one. There are in the mountains many desperate men. Some have slain an enemy who had friends influential enough to set the law in motion against them, or have escaped from prison; some have resisted the tax-collectors; many have been suspected of plotting against the government; and others are too lazy to work."

"And how do they live?" Harry asked.

"They live partly on game and partly on plunder. They steal from cultivators; they are paid a small sum by all muleteers pa.s.sing through the mountains; they rob travellers who are worth robbing; and sometimes they carry off a proprietor of land, and get a ransom for him.

Occasionally they will wash the sand, and get gold enough to send one of their number into a town to buy articles they require."

"And do they go in large bands?"

"No, senor; as a rule some ten or twelve keep together under the one they have chosen as their chief. Sometimes, if people make complaints and troops are sent against them, they will join to resist them; but this is not often. The authorities know well enough that they have no chance of catching these men among the mountains they are so well acquainted with, and content themselves with stationing a few troops in the villages."

"And is it through the robbers or the savages that so few of the gold explorers ever return?"

"It is chiefly, I think, from hardship," Dias said; "but undoubtedly many who venture down near the Indians' country are killed by them.

Some who have done well, and are returning with the gold they have acc.u.mulated, fall victims to these robbers. You must not, of course, suppose that there are great numbers of them, senor. There may be some hundreds, but from Huancabamba--the northern frontier of the western Cordilleras, where the Maranon crosses the eastern range--down to Lake t.i.ticaca on the one side, and Tacna on the other, is nigh a thousand miles, and the two ranges cover more square leagues than can be reckoned, and even a thousand men scattered over these would be but so many grains of sand on a stretch of the sea-sh.o.r.e."

"It certainly sounds like it, Dias; but perhaps those worthy people congregate chiefly in the neighbourhood of the pa.s.ses."

"That is so, senor; but even through these a traveller might pa.s.s many times without being troubled by them."

"Have you fallen in with them often, Dias?"

"Yes; but, as you see, they have done me no harm. Sometimes, when I get to the end of my journey, the mules are not so heavily laden as when I started; but generally the people for whom I work say to me, 'Here are so many dollars, Dias; they are for toll.' There are places in the villages at the foot of the most-frequented pa.s.ses where it is understood that a payment of so many dollars per mule will enable you to pa.s.s without molestation. In return for your money, you receive a ribbon, or a rosette, or a feather, and this you place in your hat as a pa.s.sport. You may meet a few men with guns as you pa.s.s along, but when they see the sign they salute you civilly, ask for a drink of wine if you are carrying it, then wish you good-day. It is only in little-frequented pa.s.ses that you have to take your chance. I may say that though these men may plunder, they never kill a muleteer. They know that if they did, all traffic on that road would cease, and the soldiers would find guides who knew every path and hiding-place in the mountains."

"Anyhow, I think it is well, Dias, that I took your advice, and handed over my gold to Senor Pasquez, for if we do fall into the hands of any of these gentry, we can lose practically nothing."

"No money, senor, but we might lose everything else, except perhaps the mules, which they could not use in the mountains. But if they were to take our blankets, and tents, and provisions, and your firearms, we should be in a bad way if we happened to be a couple of hundred miles in the heart of the mountains."

"Well, I don't think they will take them," Harry said grimly, "without paying pretty dearly for them. With your gun and our rifles, and that old fowling-piece which you got for Jose, which will throw a fairly heavy charge of buck-shot, I think we can make a very good fight against any band of eight men, or even one or two more."

"I think so," Dias said gravely. "It is seldom I miss my mark. Still, I hope we shall not be troubled with them, or with the Indians. You see, it is not so much an attack by day that we have to fear, as a surprise at night. Of course, when we are once on the hills, Jose and I will keep watch by turns. He is as sharp as a needle. I should have no fear of any of these robbers creeping up to us without his hearing them. But I can't say so much for him in the case of the Indians, who can move so noiselessly that even a vicuna would not hear them until they were within a spear's-throw."

"The spear is their weapon then, Dias?"

"Some tribes carry bows and arrows, others only spears, and sometimes they poison the points of both these weapons."

"That is unpleasant. Are there remedies for the poisons?"

"None that I know of, nor do I think the savages themselves know of any. The only chance is to pour ammonia at once into the hole that is made by an arrow, and to cut out all the flesh round a spear-wound, and then to pour in ammonia or sear it with a hot iron."

"That accounts for your buying that large bottle of ammonia at Lima. I wondered what you wanted it for. When we get into the country these unpleasant people inhabit, I will fill my spirit-flask with it, so that it will always be handy if required. Now we understand things generally, Dias. It only remains for you to decide where we had best leave the plain and take to the mountains."

Dias was silent for a minute. "I should say, senor, that first we had better journey down to Cuzco and then down to Sicuani, where the western Cordilleras, after making a bend, join the eastern branch, and there cross the Tinta volcano. On the other side are many gorges. In one of these I know there is some very rich gold sand. Explorers have sought for this spot in vain, but the secret has been well kept by the few who know it. It has been handed down in my father's family from father to son ever since the Spaniards came. He told it to me, and I swore to reveal it to none but my son. I have no son, and the secret therefore will die with me. Whether it has been pa.s.sed down in any other family I cannot say. It may be, or it may not be; but as I owe you my life, and also the debt of grat.i.tude to Senor Barnett, I feel that you are more to me than a son. Moreover, the secret was to be kept lest it should come to the knowledge of the Spaniards. The Spaniards have gone, and with them the reason for concealment, so I feel now that I am justified in taking you there."

"I am glad of that, Dias. a.s.suredly the gold can be of service to no man as long as it lies there, and it would be better to utilize it than allow it to waste. I need not say how grateful I shall feel if you can put me in the way of obtaining it."

"That I cannot absolutely promise," he said. "I have the indications, but they will be difficult to find. Three hundred years bring great changes--rocks on which there are marks may be carried away by torrents, figures cut in the cliffs may be overgrown by mosses or creepers. However, if but a few remain, I hope to be able to find my way. If I fail we must try elsewhere; but this is the only one of which I have been told all the marks. I know generally several places where great treasure was hidden, but not the marks by which they could be discovered, and as we may be sure that every measure was taken to hide the entrances to the caves, the chances would be all against our lighting upon them. I may say, senor, that, great as was the treasure of the Incas, that of the Chimoos or Chincas, a powerful people who inhabited part of this country, was fully as large; and traditions say that most of the treasures hidden were not those of the Incas, but of the Chimoos, who buried them when their country was invaded by the Incas.

"This is certainly the case with most of the treasures hidden to the west of the mountains. It was so at Pachacamac; it was so at Truxillo, where the Spaniards found three million and a half dollars of gold; and it is known that this was but a small h.o.a.rd, and that the great one, many times larger, has never been discovered. Probably the secret has long been lost; for if there are but few who know where the Incas buried their gold, it may well be believed that the exact locality of the Chimoo treasures, which were buried more than eight hundred years ago, is now unknown, and that nothing but vague traditions have been handed down."

"That one can quite understand," Harry agreed, "when we consider how many of the Chimoos must have fallen in the struggle with the Incas, and how more than half the population were swept away by the Spaniards, to say nothing of those who have died in the wars of the last thirty years. It seems strange, however, that the treasures in the temple of Pachacamac were left untouched by the Incas and allowed to acc.u.mulate afterwards."

"It was so generally regarded as the sacred city," Dias said, "that, powerful as they were, the Incas did not attempt to interfere with it, as to do so would certainly have stirred up a formidable insurrection of the natives throughout the whole of their territory; and instead, therefore, of taking possession of the temple and dedicating it to their own G.o.d, they allowed it to remain untouched and the worship of the old G.o.ds to be carried on there, contenting themselves with building a temple of their own to the Sun-G.o.d close at hand."

"Whether any treasure we find belonged to the Incas or to the Chimoos is of no consequence whatever. I certainly think that before entering upon what would seem to be almost a hopeless search for such stores, we should try this place that you know of. In that case it seems to me, Dias, that if we had gone down the coast to Islay, and up through Arequipa to Cuzco, our journey would have been considerably shorter."

"That is true, senor, but we should have found it difficult to take a pa.s.sage for our mules; the steamers are but small craft, with poor accommodation even for pa.s.sengers. And besides, until we had made all our arrangements for the journey from Lima, I could hardly say that I had made up my mind to bring you to this place. Only when you and your brother saved my life did I feel that I was bound to aid you, even to the point of divulging the secret. It is different now from what it was when it was first handed down. At that time the Spaniards were mercilessly slaying all known to be in the possession of any secret connected with gold, and every discovery of gold entailed the forced labour of thousands more of the natives. Well, senor, all that is changed; we are our own masters, and those who find mines are allowed to work them on payment of certain royalties. There is, therefore, no good in keeping a secret that has been useless for hundreds of years."

"Certainly, Dias, you will have the satisfaction of knowing that you are injuring no one by the act, and are besides doing a very good action to my brother and myself.

"Well, Bertie," Harry said when Dias had left the room, "I think we may congratulate ourselves. For the first time I really think there is a chance of the expedition turning out a success."

"It certainly looks like it," Bertie agreed. "For your sake I hope it will be so. As for me, I am quite content; what with Indians and brigands, wild beasts, alligators, and snakes, the journey is likely to be an exciting one."
