MOSQUITO SCOUTING WORK. 319 



numerous small pools in the uneven muddy bottom which were 

 ideal breeding places for fresh-w^ater mosquitoes, including 

 Anopheles. , Stones have been dumped ^ilong the shallow edge 

 and are overgrown with low bushes and weeds. Mosquito 

 breeding must take place along this edge at all times during a 

 normal season. The large easterly portion of the pond contains 

 water and is stocked with fish. While this part of the pond was 

 not examined, there is much brush along the edge and the condi- 

 tions are probably similar to those of the small pond. 



To make Dodge pond safe I would suggest that the edge be 

 made more abrupt by filling and that any brush growing near 

 the edge in the water be removed, so as to insure a clean edge 

 with no small pools that cannot be visited by small fish. 



The Pataguanset River, west of the road at this point, was 

 examined for a short distance. This stream has clean edges 

 and should be free from mosquito breeding. About one hun- 

 dred feet west and parallel to the river is a swampy area, 

 apparently without good drainage. Draining this into the river 

 would do away with a possible Anopheles-hreedmg area. 



Middle Pond. This pond at Crescent Beach was examined. 

 A driveway cuts it off from the salt water, but a large drain 

 extends under the driveway, through which, I was told, the 

 tide comes in. I was afterwards informed that there is a gate 

 in the drain keeping the tide out and that the pond contains 

 fresh water. Fish were numerous and no mosquito larvae were 

 observed. If this is maintained as a fresh-water pond the edge 

 should be watched more carefully than would be necessary if it 

 was washed by the tide. 



Lower Pond. A large fresh-water pond south from Middle 

 pond. At the north end is a cat-tail and sphagnum swamp 

 extending northward and then easterly around an area of higher 

 land called the "Island" ( ?) and connecting with the Middle 

 pond. The edge around the rest of Lower pond is clean and in 

 good condition. A portion of the swamp along the east side was 

 examined and no suspected breeding places were observed. 

 Where the driveway crosses this swamp to reach the "Island" 

 is a bridge over a small ditch which extends into the Middle 

 pond. The ditch has long been neglected and consists merely 

 of a series of small pools which were found to contain larvae of 

 Culex. This drain should be opened at least from the bridge
