The author addresses some typical questions of overseas societies concerning the various roles and activities and the factors to be considered in constituting a voluntary organisation. It is concluded that while it is impossible to foresee every combination of circumstances which may surround the birth of a voluntary TB association, personal enthusiasm, patience, and mental flexibility can overcome every obstacle. In creating a voluntary society, the first step to educate the community as a whole, is being taken. Such a voluntary association can be thought of as a working model which reflects the state of general enlightenment. For this slow process of education, there is no substitute. No hygiene or medical services will be really effective unless the will-power and interest of a significant number of ordinary people are aroused.
