400 AGRICULTURAL EXPERIMENT STATION. 



at Cape May, and at that time Mr. Viereck began a record of 

 the vegetation found on the areas where breeding is most active. 

 Explorations were also' carried further inland and breeding places 

 for Anopheles and the fresh-water Ciilex were located. 



As it was a matter of decided importance to determine 

 whether C. solhcitans bred in the marshy lowlands along the rail- 

 roads and at the edge of the highland, the whole stretch from 

 Cold Spring to Anglesea Junction was carefully collected over, 

 with the result that not a larva of this species was found. This 

 is a vital matter to Cape May, because with a safe highland at the 

 point and on the bay shore, if the north or land side be not dan- 

 gerous, the problem of cleaning out the narrow shore strip be- 

 tween Cape May Point and Sewell's Point becomes a very simple 

 engineering problem. Adults of sollicitans are horribly abund- 

 ant all summer everywhere in the territory just mentioned, and 

 Mr. Viereck's absolute failure to find larvae so near the coast, 

 confirms my conclusions from observations made further inland. 



June 26th, I covered part of the territory with Mr. Viereck and 

 was surprised to find Anopheles crucians the common species of 

 that genus. Tlie species had been rarely found, elsewhere in the 

 State, and its early stages were yet unknown ; therefore Mr. 

 Viereck was directed to work out its life cycle. 



June 27th, egg-filled females of sollicitans were numerous and 

 everything bid fair for a new brood. At about that time a very 

 high tide covered the pool areas and left "killies'' everywhere. 

 But adults enough had emerged to make life interesting and early 

 in July the proprietor of the house at Sewell's Point "swept mos- 

 quitoes out of a room where they had collected during the night 

 to a depth of nearly an inch." 



July 7th, half-grown lan-se were found at Two-Mile Beach, 

 but none at Cape May, where mosquitoes decreased in number, 

 leaving only gravid females in the damp places where larv^s 

 would be expected should they fill up later. 



July nth, Mr. Shields, of the Cape May Real Estate and Im- 

 provement Company, went over the mosquito-breeding areas on 

 Poverty Beach with Mr. Viereck and agreed to ditch and drain 

 them. Mr. Viereck had been instructed to offer every possible 

 help to any individual or body that showed any disposition to do 

 active work, and he did not only give such help when asked for, 

 but interested a number of local people in his work. 



July 13th, came a heavy northwest rain, filling all pools, and 

 July 14th, recently-hatched larvae of the fourth brood were 

 abundant everywhere. The search for sollicitans larvae along 

 the highland was rewarded by finding a few of them in a pool at 

 the corner of a corn field where it joined the marsh.
