The treatment of the copper-colored Indians was accompanied by the same acts of inhumanity that later were meted out to the black Africans, with the same consequences of making both conquered and conquering wilder. From that time wars between the Indians became more common; prisoners were dragged from the interior to the coasts to be sold to whites who chained them to their boats. Yet the Spaniards at that period, and long after, were one of the most civilized nations of Europe. The light that art and literature shed over Italy was reflected on every nation whose language stemmed from the same source as that of Dante and Petrarch. One might have expected a general sweetening of manners as the natural consequence of this noble awakening of the mind, this soaring of the imagination. But across the seas, wherever the thirst for riches led to the abuse of power, the nations of Europe have always displayed the same characteristics. The noble century of Leo X was marked in the New World by acts of cruelty that belonged to a barbaric past.

A journey to the Tenerife volcano's summit is not solely interesting for the amount of phenomena available for scientific research but far more for the picturesque beauties offered to those who keenly feel the splendors of nature. It is a hard task to describe these sensations for they work on us so much more powerfully the more they are vague. When a traveler must describe the highest peaks, the river cataracts, the tortuous Andes valleys, he risks tiring his readers with the monotonous expression of his admiration. It seems better suited to my intentions in this narrative of my journey to evoke the particular character of each zone. We get to know the features of each region better the more we indicate its varying characteristics by comparing it with others. This method enables us to discover the sources of the pleasures conferred by the great picture of nature.
