One of the results of the World War has been a widespread desire to see the forces of science which proved so mighty in destruction employed generally and systematically for the promotion of human welfare. World Book Company, whose motto is The Application of the World's Knowledge to the World's Needs, has been much in sympathy with the movement to make science an integral part of our elementary education, so that all our people from the highest to the lowest will be able to use it for themselves and to appreciate the possibilities of ameliorating the conditions of human life by its application to the problems that confront us. We count it our good fortune, therefore, that we are able at this time to offer Common Science to the schools. It is one of the new type of texts that are built on educational research and not by guess, and we believe it to be a substantial contribution to the teaching of the subject.
