is the only known means of transmission of the disease. 

 In conclusion it would be well to show what is gained 

 beyond the improvement in health of the community 

 which is alone sufficient " excuse " for the expendi- 

 ture of many times the cost of the present cam-

Fruit growing is the most important industry of 

 Penryn, and like all forms of agriculture is dependent

 spread the report that the district is malarial, making 

 it increasingly difficult to obtain labor, and therefore 

 fruit may be spoiled or not even picked for lack of 

 men to gather and pick it, another direct loss to the 

 employer. Finally, the district having the name of 

 being malarial, real estate values depreciate, a loss to 

 the owner. A typical case of the latter is personally
