In 1849 Mr Taunton measured the flow of water from 

 the Seven Wells, when it reached 3,780,000 gallons per 

 day. In 1859 during the dry Autumn the discharge was 

 only 100,000 gallons per day, clearly showing that this 

 great difference of the flow is due to or dependent upon 

 the rainfall of the season. 



On its way from its sources, the Churn runs about 5^ 

 miles over the Upper Lias, receiving continued additional 

 water from the springs of the Inferior Oolite above at the 

 Cubberley and Cowley Fauhs, at Cockleford and the 

 Fault at Colesbourn. In 1859 Mr Simpson, C.E., measured 

 the stream which was found to have considerably increased, 

 the discharge of the spring head, being 1 1 cubic feet per 

 minute, or 99,000 gallons per day.

At this distance [sYz miles) the Upper Lias Clay terminates, and the 

 Churn traverses or runs over the Oolitic Rocks. A reduction in the 

 flow immediately took place, and the result of the gaugings was as 

 follows : — 

 After 6^4 miles the flow was 290 cub.ft. per. min. or 2,610,000 gals, pr.dy.
