been drained and 3,633,974 feet of ditches, 10 inches wide by 

 30 deep, have been cut. Practically no mosquitoes have de- 

 veloped on this vast area since the work has been done and the 

 eggs with which the marsh is littered are constantly growing 

 less so that with each water covering fewer larvae hatch.

First International Entomological Congress. 



BRUSSELS, BELGIUM^ AUGUST FIRST TO SIXTH, 1910. 



In the middle of August of next year the Eighth Internation- 

 al Zoological Congress takes place in Graz, Austria. Such 

 meetings further science not only by the communications and 

 the discussions connected therewith but especially through the 

 opportunity offered to zoologists to come in personal contact 

 with one another. 



It is evident that entomology plays a very subordinate role 

 at these Zoological Congresses. The number of entomologists 

 who take part in these assemblies and the time which can be 

 spent on this branch of zoology is small in proportion to the 

 multitude of persons engaged in entomological research, and 

 the great advance which this science has made. The import- 

 ance of entomology in agriculture and medical matters becomes 

 more and more recognized and we therefore think the time ap- 

 propriate to unite in one distinctive congress all the entomolo- 

 gists with their different branches and to create an Internation- 

 al Standing Committee as a central organization to forward 

 entomological interests. 



One of the chief objects of this undertaking is to bring 

 entomologists in closer relations with general zoology on the 

 one side, and with the practical side of entomology on the 

 other. 



With this in view we propose that an Entomological Con- 

 gress be called every three years, about two weeks before the 

 Zoological Congress, so that propositions and conclusions of 

 general importance can be brought forward for discussion. The 

 First International Entomological Congress will hold meetings 

 in Brussels from the first until the sixth of August, 1910, at
