of untold millions of salt marsh forms, which while they bred exclu- 

 sively on the salt marsh migrated from 30 to 40 miles inland. No 

 matter how earnestly a municipality in the zone covered by these 

 salt marsh species might endeavor to rid itself of mosquitoes, the good 

 results of the prevention of the local breeding were always likely to- 

 be obscured by the influx of salt marsh broods. In the year 1906, 

 the legislature passed a bill carrying an appropriation of $350,000 to 

 be expended in the control of the salt marsh mosquitoes. Operating 

 under this law about one fourth of the 200,000 acres of salt marsh 

 have been drained, and the prevention of salt marsh mosquito breed- 

 ing made in these areas merely a matter of keeping the drainage sys- 

 tems in operation. This drainage has covered the salt marsh along 

 the coast from Secaucus on the north to a point some distance below 

 Barnegat. Approximately $115,000 have been expended in this 

 drainage. It is probable that already several millions have been 

 added to the rateables of the state through this work of drainage, and 

 the completion of the work cannot fail to increase the rateables of the 

 state by less than twenty-one or twenty-two million dollars. This 

 drainage, the investigation which preceded it, the convincing of the 

 people of New Jersey that the drainage would control the salt marsh 

 species of mosquitoes, and that it should be taken up without further 

 delay, was the work of Dr. John B. Smith. When the salt marsh is 

 all drained and the salt marsh mosquitoes eliminated from considera- 

 tion, there still remains the problem of controHing the local breeding 

 species. To meet this condition, the New Jersey legislature of 1912 

 passed a County Mosquito Extermination Commission law under 

 which every county can have its local mosquito extermination com- 

 mission and provide its own funds for the cleaning up of its own mos- 

 quitoes. Two counties in New Jersey have taken advantage of this 

 law already and have produced results of such a nature as to encourage 

 the. other counties of the state. 



De. L. Howard: I should like to ask Mr. Quayle what is now 

 being done in California. 



Mr. H. J. Quayle: The work in 1904-5 was successful, but the 

 following year the earthquake destroyed parts of the levee and it has 

 gradually become weaker each year since. The people of that section 

 are now, however, beginning the construction of a permanent levee 

 and are attempting to make the area within permanently safe by 

 ditching. The construction was just begun when I left California. 



President W. D. Hunter: This is the only paper on mosquitoes. 

 Is there any further discussion? 



Mr. C. F. Hodge: I have nothing new to report on the mos- 

 quito work execpt that we have done away with screen windows and
