 RAT-PROOFING BARNS AND STABLES BY ELEVATION OF CONTENTS 

 The baled hay in this case has been raised so as to give rats no place to hide 



ever conducted against rats has been that 

 cf the United States Public Health Serv- 

 ice for the purpose of eradicating bu- 

 bonic plague from San Francisco and 

 New Orleans and to prevent its gaining 

 a foothold in other American ports, but 

 the results were much less than they 

 might have been with more extended 

 cooperation. 



Zuschlag and others who have given 

 the rat question serious study have 

 agreed that it will be extremely difficult 

 to secure the far-reaching results so de- 

 sirable in the control of this public men- 

 ace except by international action. The 

 fact that when rats are destroyed in one 

 area they tend to reinfest it from sur- 

 rounding regions greatly lessens the ef- 

 fectiveness of local campaigns. For this 

 .reason, while local campaigns are useful 

 and extremely desirable in relieving local 

 conditions, the final great public relief 

 will come when the campaign is broad- 

 ened to international proportions. 



At this time, when all civilized nations 

 are care-ridden with the fear that gaunt 

 Hunger may stalk through the world, it 



is essential that foodstuffs be safe- 

 guarded as never before. To accomplish 

 this the main sources of preventable 

 waste should be located and controlled. 

 The foregoing pages have shown that 

 among these elements of waste the house 

 rat stands preeminent and deserves the 

 most serious attention. 



RATS SHOULD NOT BE TOLERATED AT A 



TIME WHEN THE ENTIRE WORLD 



PEARS A WORLD FAMINE 



The remedies against this pest are com- 

 paratively simple and may be put in ef- 

 fect to advantage by every householder, 

 as well as by mercantile establishments 

 and organizations. For modern commu- 

 nities to continue to harbor these loath- 

 some parasites is merely to prolong the 

 survival of careless methods of individ- 

 ual and community housekeeping inci- 

 dent to barbarous times. Every health 

 officer and every well-informed person 

 knows the extending menace these pests 

 present to himself and neighbors. Why, 

 then, should we not cease feeding and 

 sheltering: them ?
