450 AGRICULTURAL EXPERIMENT STATION. 



(3) Territory (C). The land here is good for 600 feet in from the north 

 of the river and for 200 feet in from the west. Then it becomes bad, forming 

 a kind of basin. We have drawn a main ditch through the middle of it from 

 the river to the creek. On either side ditches 60 feet apart are drawn. The 

 necessity for having them 60 feet apart is this : there is not much surface 

 water. There is a vast network of holes filled with water, and to drain these 

 it is necessary that the ditches be close together. In this place we found the 

 greatest breeding. 



(4) Territory (D). There is a spot of high ground here. But in places 

 where ditches are drawn are depressions, which we found prolific breeders. 



(5) Territory (E). Here there are a number of low places, in from the 

 shore, where breeding goes on. The trouble here, as in the rest of the places, 

 is that between the low places and the shore the land rises, making it impos- 

 sible for the water to get to the river. The land rises only a very little, but 

 enough to keep the water back. Ditches cut to the river would lead the 

 water off. 



(6) Passing to the Perth Amboy side of the Raritan river, we come to two 

 low places between Weber's brick works and the National Fire-Proofing Com- 

 pany's works, about which the map tells all that is necessary. 



(7) Territory (F). Here we have drawn a main ditch through the middle 

 of the bad territory, with ditches on either side. 



(8) Territory (G). We have done the same with (G) and with (F), vary- 

 ing the length of the side ditches according to the extent of the bad area. In 

 both (F) and (G) we have not made the side ditches close together, because 

 the territory is not very bad. 



(9) Territory (H). We have drawn a main ditch to lead the water into 

 the creek, and where the area is bad have placed side ditches, varying in length. 

 The land here is, like (C), a network of holes, in which great breeding- 

 goes on. 



(10) Territory (I) is not as bad as (H), and less close ditching will suffice. 

 (,11) Territory (K) is a comparatively small portion of bad area. 



(12) Territory (J). Here the character of the ground varies. Some parts 

 have sui'face water, others arc a network of holes, and some places are good. 

 But in general the territory is very bad, and only straight ditching into the 

 creek will suffice. 



(13) Territory (L) has the same character as (J). Surface water is a 

 little more in abundance. 



(14) Territory (M) has a number of depressed places about 15 feet in 

 diameter which are breeders. 



(15) The soil. The soil on both sides of the river, the South and the Perth 

 Amboy sides, is the uniform marsh soil, covered with various kinds of grass 

 and with cat-tail growth. It will easily maintain a ditch. 



(16) Along the eastern side of the point or headland, about 50 feet in from 

 the shore, are a number of salt holes. They are deep. Fish get in them and 

 no breeding goes on.

Report on the Vicinity of Sayrevillc. 



(i) On the Sayreville side of the river the ground is generally good, being 

 used for haying purposes. But in places A and B there are groups of holes, 

 mostly small, many being only one foot in diameter, and these are breeders. 



(2) Passing on to the other side of the river, at territory C the breeding is 

 large and confined to small depressions, making ditches at intervals of 60 feet 

 necessary. 



(3) On this side of the river there is a general submergence of the land. 

 and breeding goes on. On the right of the clay railroad the land is good for 

 400 feet in from the shore. Here we have drawn a long ditch intercepting 

 the parallel ditches, with every fifth ditch running into the river. Besides the 

 prevalence of surface water, there are also groups of holes in which breeding
