Others who have spent nights in an Indian jungle will have noticed this period of rest, which varies a little according to the season of the year and the phases of the moon, and which as a rule extends from midnight to 4 a.m. Between these hours killers sleep. And those who go in fear of them are at peace. It may be natural for carnivores to sleep from midnight to 4 a.m., but I would prefer to think that Nature had set apart these few hours so that those who go in fear of their lives can relax and be at peace.
