It has been said that you can judge persons by their enemies as well as by their friends. Every ship is a romantic object, except the one in which we sail. Unlike other animals, bats do not require a nest or cave or covered shelter. All they need is something from which they can hang by their claws. The young bat, or batling, clings to the breast of its mother when she searches for food.
Bats cover themselves with their wings when at rest, thus providing their own shelter.
Scientists of the nineteenth century believed that matter and energy were two different things, neither of which could ever be destroyed. With the development of much more exact measuring instruments, present-day scientists have proved that when a chemical change, such as the burning of coal, takes place the mass of ashes and carbon dioxide is not exactly the same as the mass of unburned coal, since a tiny amount of the matter or mass has been changed into energy in the form of light or heat. It is difficult to convince first-year students that education does not consist of a curriculum in a business administration, in engineering, or in the liberal arts. Education is a process that should continue for an entire lifetime. There are many who appear to live merely to hinder happiness, and whose descendants can only tell of long life that it produces suspicion, peevishness, and persecution.
