112 ARTESIAN WELLS ON THE ATLANTIC CHAST. [btjli,. 13*. 
of the county of which I have learned, are in Trenton, and the geologic 
data are not sufficiently definite for water prediction outside of the 
vicinity of these wells. The success of the wells at Hightstown indi- 
cates that water may be expected in the basal and higher Raritan 
beds and at the base of the Matawan at some localities, if not through- 
out the region. The waters in the Trenton wells appear to be in part 
from the base of the Raritan formation, but probably in part also from, 
the superficial Trenton and Columbia gravels. They afford a large* 
supply of water, and no doubt the area of the water-bearing beds is: 
considerable in the Trenton region. 
WESTERN BURLINGTON COUNTY. 
This region has been quite extensively explored for water, and there> 
are several wells which yield a large supply. The basal Raritan waters, 
have been found in the Maple Shade well at a depth of 375 feet, in. 
the deeper well at Bordentown at a depth of 195 feet, and possibly also- 
in the Riverton well at a depth of 50 feet. The Riverside well passed 
through the horizon into the crystalline rocks and reported no water- 
in the basal Raritan beds, although an abundant supply was found in 
higher beds at a depth of 45 feet. 
The well at Burlington, which obtained no water down to the depth, 
of 200 feet, did not reach the basal beds, nor did the deep well at Mount 
Holly. The Columbus well, at a depth of 715 feet, and the Moorestowni 
well, at 457 feet, were probably very near the basal beds, but evidently 
not in them. From this evidence it is not possible to make a predic- 
tion as to the general extension of the basal Raritan waters in the 
western portion of the county, but I believe that they will be found to 1 
be widespread. The waters at 2G0 to 300 feet in the Maple Shade well^, 
at 253 feet in the well east of Burlington, at 212 to 250 and at 320 
and 344 feet at Moorestown, at 45 feet at Riverside, at 442 to 457 feet; 
at Mount Holly, at 128 feet 1 J miles south of Burlington, and at 338 to 
356 feet at Columbus, indicate a wide extension of horizons within the 
Raritan formation above its base. The waters in the Mount Holly 
and Columbus wells were, however, only in small amount, and they 
were ferruginous. The supplies from the other wells are reported not 
to be large. 
The basal Matawan water horizon appears to extend only a short 
distance into the southwestern corner of the county. It has proved 
very satisfactory at a depth of 130 feet at Moorestown, 124 feet near 
Rancocas, 46 feet at Cinnaminson, and probably at 316 feet near Marl- 
ton, and was noted at 136 feet in the Maple Shade well. At Fellowship 
it promised to yield a supply at 200 feet, but this was not utilized. At 
Columbus, at 156 feet, it yields a fair supply of ferruginous water, but 
at Mount Holly no water was reported. In the Collingwood well the 
gravel was reported at 125 feet, but no water was obtained from it. 
The Hartford well stopped in dry beds about 50 feet above the hori- 
zon. I am quite confident that this water may be expected throughout *
