“On the contrary, it is very light, just sufficient to meet the expenses of the government mining bureau. The tax is fifteen dollars a year for every mine,—gold, silver, nitrate of soda, salt, petroleum,—no matter what it may be.”

“And how would we ‘prove a claim,’ as they say in the States?”

“Did you inquire in Lima whether any mines had been reserved in the locality where we intend prospecting?”

“No, señor, for we did not wish to attract attention to that section of the state.”

“You were doubtless right. It was perhaps unnecessary. In all probability no one has sought treasure in that region. Still, that point must first be definitely settled. The government issues a quarterly statement, called the ‘padron,’ in which are given the boundaries of all new claims. These padrons are indexed, and it is possible to learn the location of all mines in a given region. If we discover valuable properties where old Huayno said they were located, or anywhere else, we will at once stake off the land, just as is done in the United States, then return to Lima, examine the padron index, and if no one else has a claim we will notify the Deputy Commissioner of Mining that we desire title.

“He will issue us a document, upon our payment of the first year’s tax, which will be similar to the ‘patent applied for’ paper given in the United States. Within ninety days after receiving this, it will be necessary to return to the mine with one of the officials of the mining department and an official surveyor, whose expenses for the trip we shall be compelled to meet. These will fix the actual boundaries, and upon their return to Lima a document will be issued giving us the right to mine the property, and guaranteeing our sole possession so long as we pay the annual tax.”

“That all seems very simple,” said Harvey.

They had few adventures during this stage of the journey. Several times wild animals crossed their paths, but the young men had learned wisdom on the trip from Chicla to Huari, and Señor Cisneros was an old woodsman, so they were always on the lookout. Game continued plentiful, although the country grew more open each day.

The Marañon changed from a slow-running stream to a broad, rapid-coursing river; in places were cataracts, and the shore line became uneven, boulders being piled so high that the way between them was difficult to find. In this rough country they were once all day going three miles and were exhausted when night came. Harvey and Ferguson had large blisters on their feet, and the other two proposed that they rest for the twenty-four hours following; but the Americans were too anxious to proceed, being so near the journey’s end, and the next morning, binding pieces of a handkerchief around the bruised places, they announced themselves able to push ahead.

This was the twelfth day from Huari, and all agreed that at any time they might come upon the great rock that marked the way to the mine. They were certain they had not passed it unobserved, for since the fifth day from the village they had not moved a step forward after dusk or until morning was well advanced. When compelled to make detours, one or more of them had ascended every half hour to some eminence, like a tree or a high mound, and had carefully surveyed the right bank to the water’s edge.
