REPORT ON MOSQUITOES. 459 



many adults were found, all sollkitans, without exception. The neighboring 

 small ditches, or creeks, have steep sides, which shows that ditching could 

 be done in this locality. Mad Horse creek has a very strong tide, both ebb 

 and flood. 



Monday, June 27th. — At 6 A. M. we left Mad Horse creek. The character 

 of the shore remains unchanged. The sand on the shore is continuous, but 

 the marsh keeps close to the water's edge. We ran to Fishing creek and 

 examined the neighboring marsh, noting places marked a, b, c, as character- 

 istic of the marsh. At (a) there were breeding places. It is located in the 

 centre of the creeks and might easily be treated. The marsh grass was long 

 and thick. The turf solid. At (b) we got specimens of larvae — vial No. 8. 

 The marsh was dry and like in character as at (a). At (c) many bad spots 

 were found, but all were dry. The sod was thick and soil pasty and heavy. 

 In all this territory the creeks (from Cohansey up) have reeds on the bank. 

 Three-square grass is abundant, but the marsh grass areas are extensive and 

 cut yearly. The character of the shore to Hope creek is as below Fishing 

 creek. The marsh about Hope creek was tramped at places marked (a), 

 (bj, (c) and (d). The water in the creek at (a), (b) was salt at low tide. 

 Sunday night, June 26th, a thunder storm caused a half hour's rain, but 

 very little of the water was visible on Monday. The marsh grass in this 

 locality has grown thick and long. At (a) and (b) the marsh is in a good 

 condition, the breeding places being few and in places marked. The sod 

 is thick and soil solid. Few adults were found. At (c) there were a 

 large number of bad holes. Marsh and three-square grass, rat houses and 

 tracks were observed. At (d) there were a few bad spots. Vial No. 8 was 

 obtained in this locality. The character of this part of the marsh is thick 

 turf and firm clayey under soil. The Delaware shore continues uniform 

 as far as Alloways. Off Stony Point the dredging operations in the river 

 were noticed. 



We ran up Alloway"s creek to Hancock's Bridge. On the left or north was 

 reclaimed land, and cattle feeding. On 'the left or north side, at the mouth, 

 the reclaiming bank was broken down, but has lately been repaired. The 

 dredge No. 2 of Houston Rickards Dredging Company, Girard Building, Phil- 

 adelphia, Pa., was at Hancock's Bridge at the time of our visit, taking mud 

 out of the creek and making a bank. 



Tuesday, June 28th. — On the south side of the mouth of AUoway's creek there 

 is some marsh, a large area of three-square grass, some breeding places, few 

 adults, no larvae, and cattle put out to pasture for the entire season were 

 observed. The breeding places were not numerous. The grass was thick and 

 the soil was firm and hard. The territory north of Salem is safe. Numerous 

 creeks and inlets make the area safe. High tide covers the marsh opposite 

 the northern end of Reddy Island, and the marsh at the mouth of Salem creek 

 showed no breeding places. 



Wednesday, June 28th, 1904. — We ran back to Stow creek and up Stow creek 

 to point marked (9). A shower Sunday night and rain Tuesday night made 

 the marsh wet in some parts. In .some of the places previously noted we got 

 vial No. 9. The young larvae were found in many pools, though not in great 

 abundance. On the right side (up stream) the holes were most numerous. 

 The marsh was solid and had a good sod. On the left there was better marsh 

 grass (length and thickness). There were a few breeding places. Reed along 

 bank five feet high. 



Thursday, June 30th, 1904. — We went south of Cohansey creek as far as Mid- 

 dle Marsh creek. The neighboring marsh is famed for mosquitoes among 

 boatmen. We navigated in a row-boat. The rain of Sunday and Tuesday 

 had filled many places such as were found dry further north. Tube No. 10 

 was filled on left of mouth of creek (toward Cohansey"). There were a large 

 number of breeding places, few adults (solUcitans). The marsh has a heavy 

 sod and the under soil is firm. The marsh affords a hay crop, but the breed- 

 ing places cut up the mirsh considerably. Sedge grows near bay shore, and 

 this part of marsh (200 feet back) is safe. There are numerous creeks. The 

 1)rceding area lies in a <ort of ba'^in in the conu r. The territory within 150 

 feet of creeks is safe.
