The Baron in the Trees by Italo Calvino:
Cosimo was in the magnolia. Although its branches were close together, this tree was easily accessible to a boy like my brother, expert in all species of trees; and the branches stood up to his weight, although they weren’t very large and were of soft wood that the tips of Cosimo’s shoes scraped, opening white wounds in the black bark; it wrapped the boy in a fresh scent of leaves as the wind stirred them, turning them to a green that was now opaque, now bright.
But it was the whole garden that gave off a perfume, and although it was so irregularly dense that Cosimo still couldn’t see it all, he was exploring it with his sense of smell, and he tried to distinguish its various scents, which had been known to him ever since, carried by the wind, they reached our garden and seemed to us one with the secret of that villa. Then he looked at the foliage and saw new leaves, some as big and shiny as if a film of water were running over them, some tiny and composite, and trunks that were all smooth or all scaly.
