- "The Valley of Decision", Edith Wharton.
The site of the village, from a sanitary point of view, was a very bad one, not only because it was low and confined, but because in the valley immediately back of it there were a number of stagnant, foul- smelling ponds and pools, half overgrown with rank tropical vegetation, and so full of decaying organic matter that when I passed them for the first time on my way to the front I instinctively held my breath as much as possible because the very air from them seemed poisonous.- "Campaigning in Cuba", George Kennan.
