thing, and never looked into it further, it would be a very stupid, discourteous treatment of the inventor. We often treat the Maker of all things no better. When the Creator produces, as he always does, vast numbers more than can live, then we may well inquire by what means some survive, and through what causes others die before reaching adult life. We shall find that the fittest survive, those that have some advantage of teeth, or strength, or swiftness, or weapons, or ability to get food, or keep out of sight, etc. The smallest advantage will be of great service, and may win the race of life, when competition is so close. When one thou-sand men start together for a foot-race, it will be decided by perhaps less than a quarter of an inch ; had there been but ten, the victor would probably have gained by many feet.
