428 AGRICULTURAL EXPERIMENT STATION. 



From here there is a swamp that goes i,ooo feet north and extends 400 

 feet in from the bay. It is not generally bad, but in places it is. 



(21) From here north the land is like that noted in (20). At a number of 

 places there are inlets from the bay, the mouths of which have been stopped 

 with sand, preventing a rise and fall with the tide. The main water in the 

 inlet does not breed, but at the edges there are always isolated holes, which 

 are profuse breeders. 



(22) Except for the swamp near Station No. 16, the entire territory from 

 the inlet to the railroad is sand. There is not soil top enough to maintain 

 a ditch.

The conditions reported by Mr. Wagner differentiate this ter- 

 ritory from nearly all the rest of the shore, in that ditching is 

 completely cut out as a method of obtaining relief. In many 

 places the depressions have only a thin but tough coating of vege- 

 table matter that serves to hold the water long enough to permit 

 mosquito larvae to develop. By far the greater number of these 

 depressions are amenable to shovel work from the surrounding 

 sand-hills, and that is especially true of the conditions at Berkeley 

 and Ortley ; but along the bay shore the hydraulic dredge is no :es- 

 sary to secure relief. As the bay is all sand, and there are no lot^g 

 distances to be covered, even a small dredge could accomplish all 

 the necessary work in a single season. 



To complete the work at the head of the bay and continue it 

 along the main land, I sent Mr. Brehme, who reports as h'llows 

 on the territory between 



Manasquan and Mantoloking and Bay Head to Island Heights. 



Inspection made on the area between the United States Life 

 Saving Station No. 9 on the east, Brielle on the west, Manas- 

 quan Inlet on the south and Manasquan on the north, resulted 

 in finding some mosquito breeding places of little account, com- 

 paratively speaking. These places are mostly near the Manas- 

 quan River, and it \\\\\ be easy to drain them into that place by 

 short ditches that will admit live water and fish into the breeding 

 pools. None of them are of any considerable extent. 



On the south side of Manasquan Inlet to Point Pleasant there 

 is very little breeding area. There are a few places near the inlet 

 and there is a place at the end of Cook's Pond. All these can be 

 cleaned out by drainage into the inlet and pond respectively. 



There is a small breeding area on the northwest side of Twi- 

 light Lake which can be readily drained. The lake is fed from 

 the Metedeconk River, is well stocked with killies and affords a 

 good outlet for ditches.
