nections are established between them and the breeding pools, 

 the fish would provide against any possible development of larvae. 



Inspections were then made from the cedar swamps on the 

 south side of Forked River to the end of the salt marsh on Oyster 

 Creek. The cedar swamp on Forked River contains numerous 

 fresh-water pools which would seem to be ideal places for mos- 

 quito development, but the very closest collecting failed to dis- 

 cover even a single wriggler. On the very edge of the cedar 

 swamp the salt marsh begins, and not more than ten feet away 

 both Culex sollicitans and cantator were found breeding in enor- 

 mous numbers. A great many bad breeding places were found 

 here, all of which could be drained into Forked River, Oyster 

 Creek or one of the several other smaller creeks which empty into 

 Barnegat Bay. 



Between Oyster Creek and Waretown Creek is a narrow strip 

 of marsh land, and what breeding places occur here can be easily 

 ditched into the creeks or directly into the bay. There are no 

 physical difficulties and, if judiciously placed, the number of 

 ditches needed is not very large. 



From Waretown Creek to the main road at Barnegat many 

 breeding places were found ; but this also is easly cured, because 

 for two miles south of Waretown Creek the meadow is very 

 narrow and drainage is into the bay itself. For another mile, 

 from the end of this narrow marsh to the main road at Barnegat, 

 the meadow is a great deal wider, but there are a number of deep 

 creeks which would serve as outlets for such ditches as might be 

 needed. 



Breeding is bad from the main road at Barnegat to the Gun- 

 ning River, but this breeding is on the mainland and not on the 

 sedges which run far out into the bay. A number of creeks and 

 ditches — line and natural— cross this area ; but the ditches are so 

 grown up with grass and weeds that they are of no present ac- 

 count. If they were cleaned out and made serviceable once 

 more, this territory would be at once greatly improved. 



South of Gunning River is a large cedar swamp which is so 

 dense that it is almost impossible to get through it. No larvae 

 were found, despite close search. Adults were plentiful, how- 

 ever, and many were captured and examined. All were of the 

 salt marsh species, sollicitans and cantator. At the commence- 

 ment of the salt meadow bordering this swamp, extending down 

 to Manahawken Bay, is one mass of breeding places. Mosquitoes 

 develop here in enormous numbers, and drainage is not so easy 

 because of the great width of the marsh and the absence of natural 

 drainage creeks. It will be necessary to provide several wide
