PENIAL.
A three-inch well was drilled at Penial by H. Mervin in 1904. This well is now owned by.E. L. Parker and is used for general supply around the turpentine camp. This well reached a total depth of 235 feet and is reported cased IIO feet. The water is reported to rise 16 feet above the surface.
RICE CREEK.
A two-inch well drilled at Rice Creek in 1904 reached a total depth of 175 feet. This well is reported cased 6o feet. It has a small flow of sulphur water, perhaps 12 to 15 gallons a minute. The head as shown by the pressure gauge December 8, 19o9, is 25.1 feet above the surface.
RODMAN.
An attempt was made in 19o9 to obtain a flowing well at Rodman. Two four-inch wells were drilled by H. Mervin for the Rodman Lumber Company. Well No. i reached a total depth of 139 feet and is reported cased i1O feet. Well No. 2 has i 1o feet of four-inch casing; 200 feet of three-inch casing; and 420 feet of two-inch casing and was drilled to a total depth of 507 feet. The head did not increase with depth in this well as is shown by the level of the water in either well, the head being three and onehalf feet below the surface.
Approximately one mile east of Rodman a flow is obtained. A well drilled by H. Mervin for J. P. Buie in 19o9 at this point has a head of four feet above the surface. It is a three-inch well and has a depth of 270 feet. The flow as measured December 9, 1909, is twelve gallons per minute.

Flowing wells are not obtained at San Mateo, the surface elevation of the town' according to barometric readings being ap-
