Every now and then one of the salmon in the pool would lazily roll out of water, or spring high into the air and fall back with a heavy splash. What is it that makes salmon leap? Is it pain or pleasure? Do they do it to escape the attack of another fish, or to shake off a parasite that clings to them, or to practise jumping so that they can ascend the falls when they reach them, or simply and solely out of exuberant gladness and joy of living? Any one of these reasons would be enough to account for it on week-days. On Sunday I am quite sure they do it for the trial of the fisherman's faith.
