456 AGRICULTURAL EXPERIMENT STATION. 



Thursday, June i6th, 1904. — I left New Brunswick 8 :3i A. M., and arrived 

 Bridgeton i 130 P M. The afternoon was spent in locating, getting informa- 

 tion about the creek and its banks, the tides and the use of a boat, also the 

 collection of adult mosquitoes was made, and these proved to be Culex 

 cantator, not a single sollicitans being found. The adult has not been 

 numerous in Bridgeton for the past three weeks, but, according to report 

 of residents, there were plenty of them about three weeks before my arrival. 

 All the adults 1 found were caught while I was walking the reclaimed land 

 on the bank of the Cohansey,, south of Bridgeton. I caught about eight (all 

 that got on my clothes) . During the evening I went about town and sat on 

 porch of boarding-house, but found mosquitoes scarce. 



My first operations were on the west and north bank of the Cohansey. I 

 walked three miles down from Bridgeton along the west bank This is all 

 reclaimed land. There is a high (above extra high tide) bank or dyke along 

 the creek, with sluice gates at intervals of about three-quarters of a mile. 

 These are kept in good repair, and from the condition of the ditches (amount 

 of water being small at high tide) they seem to be serviceable. I found 

 no breeding places, and, consequently, no larvae on the reclaimed land. 

 There seemed to be plenty of fish in the ditches leading to the sluice gates. 

 The reclaimed land is used for pasturing and grass. 



Friday. June 17th. — I took a short (two miles) walk north of Bridgeton. 

 I found the water fresh. The creek is much narrower. Bladderdocks, reed 

 grass and cat-tails were abundant. There is a layer of mud on bed of creek, 

 but the under soil and on banks is sandy. I found neither adults nor larva. 

 I saw nothing like a sollicitans or cantator breeding place. I turned to the 

 territory south of Bridgeton, north an,d west of the Cohansey. I went on a 

 wheel making stops along the creek at intervals where roads were found. 

 The territory is protected by a bank as far south as Greenwich. To this 

 point no marsh grass was found. Corn fields and pasturing land were found. 

 The ditches had some reed and cat-tails, but were well stocked with fish. 

 The soil was loamy and good farm land. The territory neighboring the 

 reclaimed land and back from the bank of the creek is sandy. The Cohansey 

 is fresh above the vicinity of Greenwich. 



Saturday, June iSth. — I rode bicycle to Greenwich. There is a sluice gate 

 in the bank near Molly Wheaton's Run which is out of repair. Along the 

 road at this place, on the territorj^ toward the creek, I got vial No. i. Here 

 also were found an abundance of adults, which proved to be sollicitans 

 mainly, and a few cantator. Pushing south to Buena Vista, and going about 

 a mile beyond, nothing was found in the larva state. Adults were abundant 

 as at Greenwich. The bank in the neighborhood of Greenwich was not in 

 good condition, places being found through which an exceptional high tide 

 would pass and cause a break. On June 30th I noticed in passing this point 

 in the launch that the bank was being repaired by the work of Dredge No. i 

 of Houston-Rickards Dredging Co., 714 Girard Building, Philadelphia, Pa. 

 On the bank "of the creek south of Greenwich there are some breaks in the 

 bank. There are also some places which undoubtedly are breeders, although 

 they were dry at the time I visited them. These explorations were carried 

 on to a point about a mile from Tindall's Island. If the sluice-gate is 

 repaired at Greenwich, and the bank jitst below the town is rebuilt, the im- 

 mediate neighborhood on the north bank will be safe. 



Monday, June 20th, TuesdaJ^ June 21st. — Explorations along east and 

 south bank of the Cohansey came next. The bank as far south as one mile 

 below Tindall's Landing has steep sandj'' sides. Then comes three-quarters 

 of a mile (land distance) of salt marsh. This is mostly covered by every 

 high tide. Reed and wild oats are abundant, making a feeding ground for 

 rail birds. There is some salt grass cut. I did not find any breeding area. 

 From this point west there is broken meadow. The bank in several places 

 has given way and the high tide gets in. No breeding places were found 

 until Laning's Wharf is reached. Here is salt marsh covering the point of 

 land making bend in creek. The place was quite dry but some shaded holes 

 had a few larvas and here vial No. 2 was obtained. Adults were not very
