X recent editorials in the Aiji'icidtaral 

 News the work of the United States Depart- 

 ment of Agriculture, as n whole, and of 

 several of its Bureaus, has been considered. 





The Bureau of Entomology deals with all problems 

 <I arising from the attacks of insects on agricultural crops, 



on forests, oti domestic .-uid other animals, and even on 

 man liniiscll'. 



One of the nmst de.'ti'nctive insects wliich h.-is ever 

 ajipeared as an enemy t'> agricultural crop.s is the 

 Gottiui IJoli \Vee\il. This insect mail e its way into the 

 Uniied .States from Mexico in 18y4, ar:d for most of the 

 years since that lime the Bureau of Entomojoo-v has 

 cairied on inveslig.-itions as to the best methods of 

 controlling it. In spite of the fact tliat this woik 

 has been most caiefully carried out, and th;it 

 trained Entomologists h/ive been engaged in it, the 

 Boll Weevil has steadily [irogressed across the cotton- 

 growing area of the United Stales. In 190S, it was 

 found to have crossed the Mississippi River, and it is 

 not likely that anything can be done to prevent its 

 spread to the Atlantic se.a-board, thereby infesting the 

 entire cotton belt. But akhongh it h.-is not been found 

 possible to stojj the spread of this insect, cultural 

 methods have been worked out, by means of which food 

 crops of cotton may ha grown even within the limits of 

 the infested territory. Early planting, the growing of 

 early flowering varieties, and the complete destruction 

 of all the cotton stalks in the early fall, together with 

 the collection and destruction of the infested bolls after 

 they have fallen, have resulted in considerable profits to> 

 the farmer. Much also has been done in the study of 

 the parasites and other natural enemies of this insect, 

 until now practical application can be made of the 

 knowledge thus gained. 



In connexion with the work on the Gipsy Moth 

 and the Brown Tail Moth in the Eastern United 

 States, the Bureau of Entomology has been instrumen- 

 tal in importing beneficial (parasitic or predatory) 

 insects from Europe, the native home of these two
