In the cold of Europe, under prudish northern fogs, except when slaughter is afoot, you only glimpse the crawling cruelty of your fellow men. But their rottenness rises to the surface as soon as they are tickled by the hideous fevers of the tropics.

The true theater of history is therefore the temperate zone.

Warmest climes but nurse the cruelest fangs: the tiger of Bengal crouches in spiced groves of ceaseless verdure. Skies the most effulgent but basket the deadliest thunders: gorgeous Cuba knows tornadoes that never swept tame nothern lands.

Nobody is so constituted as to be able to live everywhere and anywhere; and he who has great duties to perform, which lay claim to all his strength, has, in this respect, a very limited choice. The influence of climate upon the bodily functions … extends so far, that a blunder in the choice of locality and climate is able not only to alienate a man from his actual duty, but also to withhold it from him altogether, so that he never even comes face to face with it.
