Directions, i . The class may divide itself into three com- 

 mittees, a water committee, a milk committee, and a food com-

 with reference to its topic and report to the class. The water 

 committee will collect information regarding the source of water 

 supply, possibility of contamination, means taken to purify it or 

 to prevent contamination, means of distribution, cost, measure-

 supply. If possible the committee may visit the filter plant, 

 pumping station, or watershed.

 the source of milk, sanitation of dairies, inspection given by 

 city, conditions under which licenses are granted, need for 

 further care on the part of the city. They may perhaps visit 

 some of the dairies and report on the conditions found.

 foods used in town, inspection given foods by federal, state, 

 and local authorities, the local ordinances, care exercised by 

 local dealers in handling food supply, other steps that should be 

 taken to further protect the food supply.

 on present conditions has been presented, special attention 

 should be given to the things that still need to be done and to 

 the ways in which the members of the class can help to bring 

 these about.
