 MOSQUITOES. 



6. Keep your well thoroughly covered by a screen, especially 

 at night; mosquitoes are seldom active during the day. 



7. Screen the windows of your house, especially in the bed- 

 rooms. Be sure that the screens are effective. A fine-mesh 

 copper screen is best. 



8. Interest your neighbor, and see that he takes as much care 

 of his place as you do of yours. THIS IS IMPORTANT. 

 COOPERATION WILL ACCOMPLISH MORE THAN 

 SINGLE EFFORTS. 



The Sanitary Inspector will be glad to advise you as to the 

 best method of removing sources of malaria-bearing mosquitoes 

 from your premises. This advice costs you nothing.
