the other on the twenty-first. These were both small in number and 

 were not troublesome. 



On August 13 there occurred a northeast storm with much rain 

 and a very high tide which started an immense brood of sollicitans 

 that emerged on the twentieth and the twenty-first. The evening of 

 the twenty-second was hot and sticky with the wind blowing from 

 the west. Sollicitans began to arrive in Atlantic City, Ventnor and 

 Margate about 7 o'clock and increased in numbers for the next two 

 hours. They were also quite numerous on the Shore Road from 

 Somers' Point to Pleasantville. None, however, reached Absecon or 

 the Shore Road above until the following night when the winds 

 shifted to the south and carried a part of the brood from Absecon 

 Island. These sollicitans were accompanied by A. taenorhynchis 

 and a very few A. sylvestris. 



This was the last brood of sollicitans to give any trouble, as Sep- 

 tember and October produced very small broods. 



It is interesting to note, in looking back over the records of flights 

 of salt-marsh mosquitoes for the past seven years, that in but one 

 season, that of 191 6, was each emergence followed by north or 

 northeast winds ; in the other six seasons south, southwest and west 

 winds prevailed after an emergence. 



Fresh-water work was carried on as in the past with the efforts 

 directed toward the control of breeding of the house mosquitoes in 

 Atlantic City and thickly populated towns on the mainland. 



No changes were made in the system of inspection and good re- 

 sults were obtained until the storm of August 13, at which time 

 some few house mosquitoes emerged that were beyond our control. 



With a rainfall of 9 inches in 24 hours and at the same time a 

 record high tide, the drainage system in Atlantic City proved in- 

 adequate to carry off the water fast enough to prevent the filling of 

 cellars and basements on the beachfronts with from 4 to 18 inches of 

 water. A great many of these basements were used as store-rooms 

 for rolling chairs, furniture, carpets, clothing, etc. ; to use oil to 

 prevent mosquito breeding would have meant destroying these things, 

 and that was out of the question. 



In spite of the unusual weather conditions of the entire season 

 the number of actual breeding places of Culex pipiens found was but 

 two hundred more than was reported for the last year. * 



The appropriation was the same as in the past, $26,000, and was 

 expended in the following proportions :
