EFFECTIVE WARFARE: CONCLUSION 85 



and form a central body with a view of ultimately 

 founding an association for promoting the work of fly 

 extermination, the writer will be glad to find or meet 

 with an honorary secretary and helpers who will work 

 in the cause and economise in the necessary expendi- 

 ture of all contributions received. After the preliminary 

 efforts of starting such an association, its work will be 

 not only to urge the local sanitary authorities every- 

 where to adopt the best possible course of action, but 

 also to incessantly move public opinion to compel 

 Parliament to pass laws, capable of administration, for 

 the public welfare in this matter. 



The present booklet had its origin very many years 

 ago in the author's idea of writing an account of the 

 house-fly and its kindred, which would be interesting 

 and more truthful than much then to be found in 

 current literature. Such off-hand inconsiderate writing, 

 as appears in the " Elements of Entomology," by 

 W. S. Dallas, F.L.S., requires to be controverted ; 

 therein it is stated that the house-fly, which is "trouble- 

 some, does very little actual damage, for our only 

 real grounds of complaint are to be summed up in 

 the tickling sensation which its feet cause," &c. " In 

 its larvae state, however, it lives inoffensively enough 

 in dung." It has now seemed timely to publish my 

 long-delayed work, re-written with the object of more 

 urgently interesting the general public, in the cause of 

 the anti-fly campaign. Still, the author trusts that both 

 the deeper and the less entomologically inclined nature 

 students will find therein not only useful, but also some 

 novel information, given with not too much entomo- 

 logical technicality.
