Monument, Calvert, and Center Streets is being used by the Monticello Pure Rye Distillery, located on Calvert near Center Street. This spring is near the foot of the Wicomico terrace which runs approximately north and south along Charles Street from Fayette to Chase Streets. At this locality clear and cold water bubbles up from a coarse yellow sand at an estimated rate of 200 gallons per minute. This flow is reported to vary somewhat, but the supply is always large. The water flows by gravity to storage tanks and then through the condensers of the distillery and an ice cream factory. There was formerly another large spring located at the base of this hill about four blocks farther south, reported to be a very much. larger spring, but the point of emergence is now covered.

In the Piedmont area around Baltimore there are many springs, both large and small, some of which, like the Chattolanee Spring in the Green Spring Valley, have long been celebrated.

These spring waters are utilized in the manufacture of soft drinks and in supplying table water. Upwards of a million gallons of table water are sold annually in Baltimore and vicinity. The principal concerns engaged in this business are the Chattolanee Spring Water Company, Powhatan Spring Water Company, Rognel Heights Water Company, Royal Spring Water Company, Caton Spring Water Company, and Brooklandwood Farms and Spring Company.

The Chattolanee and Brooklandwood springs are situated in the Green Spring Valley north of the city. The Royal Springs are at Ruxton Heights. Caton, Powhatan and Rock Crystal springs are west of the city at Catonsville, Woodlawn, and Rognel Heights respectively.

Analyses of these various spring waters are given elsewhere in this report.

SHALLOW WELLS.-Shallow wells have entirely gone out of use within. the city as it is impossible to obtain an uncontaminated supply from such sources. Some shallow wells are still being used in the suburban district, but they are dangerous and it is only a question of time when their use will cease altogether. It is therefore unessential to discuss shallow wells for the Baltimore district.
