Society will take over unto itself the oversight not only of physical training and of providing that children shall be well born but also more and more the oversight of the treatment of disease, as a public necessity. We shall train the sound to care for the unsound. 7. To come with personal succor as well as with money and goods in time of flood and disaster, to visit the sick and the afflicted, to relieve the poor and unfortunate. We shall learn how to organize the vast resources in men and women who are willing but do not know how, who are undiscovered and untrained, yet who could be shaped into a great army of assistance. 8. To respond promptly to the call of societies or groups that act in the public interest; to participate in the many neighborhood coöperations. As an illustration of the manner in which a military equivalent may be determined, an illustration has been taken from some agricultural activities. Before considering the military equivalent in farm work it is necessary to give a brief description of the basis upon which the Military Training Commission will probably work in this matter. The basis, in brief, is the "man work unit" idea as developed by Dr. George F. Warren, Professor of Farm Management, New York State College of Agriculture. A man work unit is the _average_ amount of work accomplished by a man in ten hours. A horse work unit is the _average_ amount of work accomplished by a horse in ten hours. For New York conditions, _an acre_ of the following crops represents the man and horse units indicated below. In a majority of cases the numbers which follow are based upon cost accounts. In some instances, where data were limited, the results are more or less an estimate.
