ABSTRACT
Science originates in man's endeavor to answer the eternal question "why." In answer to this question, thinkers are ever on the alert to detect agreements and differences among things. The surest road to failure as an economist is for the student to begin with a special branch of the subject and pursue it to the exclusion of other studies. Specialization there must be, but this does not imply ignorance of all excepting one's chosen field. An economic fact is never an isolated datum; it is always the result of a combination of forces. Different conjectures have been made as to how or why man came to domesticate animals. The "pet theory" seems to prevail; namely, that some of the savages who caught young animals would prefer to amuse themselves by playing with the captives rather than destroying them for food. The ancient herdsmen have taught us yet another lesson, namely, that the pressure of numbers is a cause of progress.
