Mr. Max Kisliuk, Jr.: In the Bureau of Entomology during the 

 summer of 1915, Mr. Hutchinson and I performed several baiting 

 experiments similar to the ones reported by Mr. Richardson. Among 

 some of the materials used was blood of pigs secured from a slaughter- 

 house. We tested sample traps and found that pig blood was very 

 attractive — more so than any other material tried. Its odor, however, 

 is very disagreeable to man, although it apparently attracts flies very 

 strongly.

RECENT ANTI-MOSQUITO WORK IN CONNECTICUT 



By W. E. Britton, New Haven, Conn. 



At the Cleveland meeting of this Association, four years ago, the 

 writer presented figures showing that in 1912 some 2,697 acres of salt 

 marsh in Connecticut were ditched to prevent mosquito breeding 

 (See Journal or Economic Entomology, vol. 6, p. 89). 



In 1913 a contract was awarded for the elimination of all mosquito- 

 breeding places in Greenwich from the shore inland for a distance of 

 a,bout two and one-half miles, at a cost of $15,500. The major portion 

 of the work related to. inland breeding places such as fresh water 

 swamps, the overflow from springs, and surface pools, but a small 

 portion consisted of tide-water marsh which was ditched. The work 

 was not finished until 1914. 



Greenwich was formerly a malaria ridden community; it has been 

 unofficially estimated on good authority that 900 cases of malaria 

 occurred there in a single season. In 1914 up to September it was 

 reported that there had been only 36 cases, of which only 15 were new 

 ones. Since, according to several reports, there has been no malaria 

 in Greenwich except a few hold-over cases. At any rate it seems to be
