REGULAR INSTRUCTION 59 



will make them careful they will soon find it worth 

 their while to have the offending manure removed 

 rather than to incur his displeasure ; and if the owners 

 are well versed in the nature and the usefulness of

 distribution and the insects' population will soon be 

 under control. But at first no attempt should be made 

 to threaten the proprietors with legal proceedings ; 

 persuasion must be used always rather than force. In 

 civilised countries the people will soon realise that fly-
