MISCELLANEOUS WATER SUPPLIES IN THE VICINITY OF WASHINGTON. 
THE GOVERNMENT HOSPITAL FOR THE INSANE. 
The Government Hospital for the Insane, St. Elizabeth’s, is sup- 
plied with water from eight artesian wells, 375 feet in depth. The 
wells, pump house, and storage cistern are located in the river bottom, 
near the Eastern Branch of the Potomac River. According to the 
engineer in charge of the pump house, no solid rock was encountered 
in drilling these wells. The wells themselves are incased in iron 
pipes 6 to 8 inches in diameter and are thoroughly protected against 
surface contamination. The water is forced out of the wells by 
means of compressed air and, after leaving the outlet of the iron pipes.
