I don’t know why, but I keep remembering snake stories from days in the oil industry. Here are two related by area and outcome.
First, Dr Walter Blow, palaeontologist extraordinaire, was writing monographs on single cell foraminifera at the end of a long career which involved several years in Trinidad. He was a war hero, badly injured and so had a wooden leg fitted. While working in the swamps in central Trnidad he saw a fer de lance swimming toward him. The snake attacked and hit his leg, then swam away. You guessed, the snake chose the wrong leg.
Second, Peter Hardwick was general manager of BP Singapore when I arrived in 1974. He had worked in the Llanos area of Colombia where he had a field crew of locals. Again he was attacked by a fer de lance and bitten. However he survived, much to the surprise of the field crew. His explanation was that the snake had recently used up its venom on another attack. He was treated with awe from then on and could do no wrong!
