from one well reduced the water level to about 5 feet below the surface, 
aDd pumping 3,500,000 gallons per day from four wells reduced the level 
to about 10 feet below the surface. 
The record of one of the wells at Jameco — well No. 4a — is as follows : 
Feet. 
0-3 muck or peat. 
3-5 fine, gray gravel. 
5-7 fine, white gravel. 
7-21 sharp, yellow sand and gravel. 
21-34 fine, white sand. 
34-65 fine, yellowish sand. 
65-79 coarser, yellowish sand. 
79-137 blue clay. 
137-144 coarse, black sand. 
144-150 coarse, black sand and gravel. 
During the year 1895 the water department sunk a series of twelve 
test wells to obtain additional light on the relations and extent of the 
deeper waters which are tapped by the Jameco and Baisley's wells, and 
the results of these investigations are embodied in a report by I. M. De 
Yarona, water engineer, for 1895, now in course of publication. Mr. 
De Yarona kindly furnished advance proofs of this report, from which I 
have obtained the following records and statement of results of the 
test wells, given in order from west to east :
