"Now, Dias," Harry said, "we must talk over our plans. You said that we would not decide upon anything till we got here."
"In the first place, señor, I think it would be well to go to the north to see the Cerro de Pasco silver mine, they say it is the richest in the world. It is well that you should see the formation of the rocks and the nature of the ore; we may in our journeyings come across similar rock."
"It is gold rather than silver that one wants to find, Dias. I do not say that a silver mine would not be worth a very large sum of money, but it would be necessary to open it and go to a large expense to prove it. Then one would have to go to England and get up a company to work it, which would be a long and difficult matter. Still, I am quite ready to go and see the place."
Dias nodded.
"What you say is true, señor. I could take you to a dozen places where there is silver. They may be good or may not, but even if they were as rich as Potosi the silver would have to be carried to Lima, so great a distance on mules' backs that it would swallow up the profits. And it would be almost impossible to convey the necessary machinery there, indeed to do so would involve the making of roads for a great distance."
"At the same time, Dias, should you know of any silver lodes that might turn out well, I would certainly take some samples, and send two or three mule-loads of the stuff home. They might be of no good for the purpose for which I have come out here, but in time I might do something with them; the law here is that anyone who finds a mine can obtain a concession for it."
"That is so, señor, but he must proceed to work it."
"I suppose it would be sufficient to put two or three men on for that purpose."
"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 quantities to make mining pay. The rivers whose sands are richest in gold are in the mountains that lie behind Lake Titicaca, 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, señor, 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 Titicaca. 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 quantity 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 vicuñas, 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, señor; 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."
