174 ARTESIAN WELLS ON THE ATLANTIC COAST. [bull.138. 
Hometvood, Surry County. — This place is on Hog Island, in James 
River, about 6 miles east of Williamsburg. There are five wells at 
various points on the island, with depths from 112 to 317 feet. They 
yield large supplies of water, of which that in the deep wells is of very 
fine quality, with a temperature of 54°. The following record has 
been furnished : 
Feet. 
0-15 clay and loam. 
15-25 gravel with surface water. 
25-85 clay, blue below. 
85-112 shell marl, with hard crust of shell marl at base. 
112 ferruginous water which flows. 
112-220 marl. 
220-22H rock. 
222 water, better quality than that at 112 feet, and greater flow. 
220-287i blue clay. 
287|-290 hard rock. 
290 black water-bearing sand; 30-gallon flow; fine water. 
In the wells on the southeastern part of the island the depth to the 
lower water is 315 feet. The horizon of this lower water is probably 
basal Chesapeake, or the same as in the many wells on York and 
Rappahannock rivers. 
Jamestotvn, James City County. — This well is on Jamestown Island, in 
James River, a couple of miles above Homewood and about 5 miles from 
Williamsburg. It is 248 feet deep, and yields a large supply of fine 
water from the same horizon as that in the deeper wells on Hog Island. 
White House, New Kent County. — The three wells in the vicinity of 
White House vary in depth from 180 to 230 feet. The following record 
was supplied by Mr. P. H. Sweet, of White House: 
Feet. 
0-15 soil. 
15-25 yellow clay. 
25-65 blue fullers' earth. 
65-70? several thin rock strata, one 18 inches thick. 
70-95 soft sand rock. 
95-115 red clay. 
115-165 greensand marl ?. 
165-210 black sand. 
210 water. 
The pressure in the wells differs, but in one of them the water will 
rise to 20 feet above the surface of the ground. The water is probably 
in the basal beds of the Pamunkey formation. 
Lester Manor, King William County. — The same horizon is tapped 
at Lester Manor in three flowing wells 200 feet deep. 
Wells along the Mattapony and York rivers. — The wells in this valley 
begin at Walkerton, on the Mattapony, and occur at frequent inter- 
vals to Clay Bank Landing on the York River. They are all flowing 
wells, and yield large supplies of good water. Some of their features are 
given in the table on pages 165-167. The Walkerton well, with a depth
