of several barrels, is more injurious to vegetation and to the various 

 forms of animal life in the water — some of which destroy wrigglers. 

 Kerosene, on the other hand, does not need to be ordered in advance, 

 and may be obtained at every corner grocery. At first the oil was 

 applied in small compressed air "Auto-Spray" outfits, but later in 

 the season as the breeding became more extensive and more intensive, 

 much more oil was used and larger pumps were needed. The " Double 

 Porester" designed for fighting forest fires and made by W. & B. 

 Douglas, Middletown, Conn., is excellent for this purpose. The 

 Hardie Wheel outfit and several barrel spray pumps were given a trial, 

 but these were difficult to transport across the marsh. 



As a result of this crusade it was unusual in late summer to find 

 Culex soUicitans around the outskirts of New Haven, where in 1911, 

 this species composed about 90 per cent of the mosquitoes observed 

 in the writer's own garden and on the grounds of the Experiment 

 Station. 



There is much more work to be done around New Haven and all 

 along the Connecticut coast. Connecticut has a salt marsh area of 

 over 22,000 acres. The elimination of the salt marsh mosquitoes, 

 besides benefiting the public health, would mean thousands of dollars 

 gain to the shore resorts, summer hotels and transportation companies. 

 All property values would rise. The marsh itself through drainage 

 would yield a profitable crop. 



It is too large a problem for communities to solve separately. The 

 movement should be state-wide. State authority to drain land will 

 be asked of the next legislature and a state appropriation will be 

 sought because the work will benefit the whole state. To this end the 

 various organizations have united in preparing a bill to be introduced 

 into the next legislature, and will support it at the hearings before the 

 legislative committees. 



President W. D. Hunter: This paper is now before the Associa- 

 tion for discussion. 



Mr. T. J. Headlee: I have been very much interested in this 

 paper, and in view of the fact that many of the entomologists are 

 unfamiliar with the extent of the work accomplished against the mos- 

 quitoes in the State of New Jersey by the late Dr. John B. Smith, I 

 am tempted to give a brief account of some of the results he achieved. 

 In 1901 Dr. Smith systematically started the work in New Jersey, and 

 in 1904 published a report setting forth the results of his investiga- 

 tions. In this report it was shown that in addition to the local breed- 

 ing species of mosquitoes found more or less generally all over the 

 -country, the New Jersey problem was complicated by the breeding
