74 ARTESIAN WELLS ON THE ATLANTIC COAST. [hull. 138. 
at Weymouth at a depth of 40 feet. The distance between the two 
places is 5 miles, which is nearly directly across the line of strike. 
This horizon is thought to be the same as that in the Atlantic City 
wells at 525 feet, in the central portion of the diatom clays. 1 
MechesatanMn Creek, Atlantic County. — A well bored for C. G. Bock- 
wood about 1 miles from Atsion and 5 or miles northwest of Pleasant 
Mills passed through 158 feet of sandy clays and sand but did not obtain 
a satisfactory supply of water. 2 
Medford, Burlington County. — A boring to 70 feet yielded 20 gallons 
a minute on pumping. It was deepened to 183 feet in 1892. The fol- 
lowing record is given: 
Feet. 
0-15 sand and earth. 
15-45 marl. 
60-64 shelly layer. 
64-70 coarse gray sand. 
70-85 green marl. 
85-110 black quicksand. 
110-122 marl. 
122-157 quicksand. 
157-170 marl. 
170-175 sand, some clay. 
175-177 sand, some clay, and good water. 
177-183 sand. 
The water is stated to be first class and to rise within 17 feet of the 
surface, which is 78 feet above tide level. 3 
A well on the farm of Mr. J. S. Mills, about If miles northeast of 
Medford Station, had the following record: 
Feet. 
0-2 soil. 
2-5 clay, yellow sand. 
5-15 fine gray sand with greensand grains. 
15-23 coarse gray sand with greensand grains. 
30 olive-colored marl. 
35 dark-green marl, thought to he bottom of Upper Marl bed. 
50. . . „..liinesand with Foraminifera, Bryozoa, etc. 
70 greensand marl with Gryphea and Terebratula, Middle Marl bed • 
76 pure greensand, dark color. 
80 pure greensand, light color. 
91 pure greensand, dark color. 
104 pure greensand, chocolate color. 
120 pure greensand, dark green. 
124 gray sand with greensand grains, Exogyra, and Belemnites. 
126 g ra y sand and water. 
The elevation of the boring is 63 feet. From a comparison of the 
records it appears that the 70-foot horizon in the first well is the same 
as that at 12(3 feet in the other 4 or in the Eedbank beds. The water 
at a depth of 183 feet in the well at Medford is probably in the horizon 
at the base of the Lower Marl bed.
