He saw a large stream of beautiful water falling from the mountains above, with a loud noise....  Just then the sailor boys called out that they had found large pines.  The Admiral looked up the hill and saw that they were so wonderfully large, that he could not exaggerate their height and straightness, like stout yet fine spindles.  He perceived that here there was material for great store of planks and masts for the largest ships in Spain ... the mountains are very high, whence descend many limpid streams, and all the hills are covered with pines, and an infinity of diverse and beautiful trees.

November 27th: 

The freshness and beauty of the trees, the clearness of the water and the birds, made it all so delightful that he wished never to leave them.  He said to the men who were with him that to give a true relation to the Sovereigns of the things they had seen, a thousand tongues would not suffice, nor his hand to write it, for that it was like a scene of enchantment.

December 13th: 

The nine men well armed, whom he sent to explore a certain place, said, with regard to the beauty of the land they saw, that the best land in Castille could not be compared with it.  The Admiral also said that there was no comparison between them, nor did the Plain of Cordova come near them, the difference being as great as between night and day.  They said that all these lands were cultivated, and that a very wide and large river passed through the centre of the valley and could irrigate all the fields.  All the trees were green and full of fruit, and the plants tall and covered with flowers.  The roads were broad and good.  The climate was like April in Castille; the nightingale and other birds sang as they do in Spain during that month, and it was the most pleasant place in the world.  Some birds sing sweetly at night, the crickets and frogs are heard a good deal.

All this shews a naive and spontaneous delight in Nature, as free from sentimentality as from any grasp of landscape as a distinct entity.

In a letter about Cuba, which Humboldt gives, he says: 

The lands are high, and there are many very lofty mountains ... all most beautiful, of a thousand different shapes, accessible and covered with trees of a thousand kinds of such great height that they seemed to reach the skies.  I am told that the trees never lose their foliage, and I can well believe it, for I observed that they were as green and luxuriant as in Spain in the month of May.  Some were in bloom, others bearing fruit, and others otherwise according to their nature.  There were palm trees of six or eight kinds, wonderful in their beautiful variety; but this is the case with all the other trees; fruits and grasses, trees, plants and fruits filled us with admiration.  It contains extraordinary pine groves and very extensive plains.

Humboldt here comments that these often-repeated expressions of admiration prove a strong feeling for the beauty of Nature, since they are concerned with foliage and shade, not with precious metals.  The next letter shews the growing power of description:
