“At first sight, especially if seen from a boat, Green Hell is just a wood, silent, empty, a little aloof as it paddles its roots in the river. Except for an occasional palmtree, it might be a slice of England such as Symonds Yat on the Wye, or some parts of the Devon and Somerset border. Shady, cool and green, motionless in the sunlight, it gives an impression of beauty and security that has lured many a novice to his death. During the next seven months I began to know that forest, and to understand the fiendish, callous power that underlay the calm exterior. Under the shadow of its leaves I was tired, elated, thirsty, hungry and afraid. It hedged us in, dared us to venture through its bowers, coyly hid its water-holes from our sight, and loosed a covey of vampire bats when our animals could ill afford the blood. I make no claims against the snakes and jaguars that we met, for we sought them deliberately for our own ends. And the Indians that surrounded us were poor, driven creatures who knew no better“.
