A Tropical Forest
It took them over three weeks to reach Cuzco. They did not hurry, for they wished to keep the mules in good condition for the serious work before them. They were travelling across a plateau thickly dotted with villages and small towns, and everywhere richly cultivated. Near the summit of the mountains large flocks of alpacas were grazing, and lower down herds of cattle and sheep, while near the plain were patches of wheat, barley, and potatoes, which in turn were succeeded by fields of maize, apple and peach trees, and prickly-pears. At the foot were fields of sugar-cane, oranges, citron, pine-apples, cacao, and many other tropical fruits; while in the deeper ravines cotton was grown in abundance for the wants of the population. Here, in fact, were all varieties of climate, from the perpetual snow on the summits of the lofty mountains to a tropical heat in the valleys.

"If the Incas had been contented with this glorious plateau, which for centuries constituted their kingdom, and had passed a law against the gathering of gold and the mining for silver, they might still have been lords here," Harry said one day. "There would have been nothing to tempt the avarice of the Spaniards, for owing to the distance of the mines from the coast, the cost of carriage would have been immense, and the long sea journey would have rendered the exportation of the natural products of the country impossible. Some of the more sober-minded of the Dons might have settled down here and taken wives from among the daughters of the nobles, and, bringing with them the civilization of Spain, become valuable colonists. The Incas, before they extended their conquest over the whole of the west of South America, must have been a comparatively simple people, and would have had none of the habits of luxury and magnificence that tempted the Spaniards. The gold of South America was the ruin of the Incas, as it was afterwards the chief cause of the ruin of Spain."
