tors in each squad must hand in written reports, once a week to their district leader, besides reporting every Saturday morning in person to the assistant chief of the division. These reports show the number of vaccinations, the character of dwelling vis- ited, its exact location, etc., and are properly filed. Each vac- cinator is expected to do a full day's work, and his results are judged rather by the number of vaccinations secured than by the territory covered.

These two methods may be illus- trated as follows :
