drains. The sum of the flow from these two drains, at the time 

 of the trial, was 975 pounds per hour, or at the rate of 19J tons 

 per acre in 24 hours ; the proportionate discharge, therefore, 

 was 12 tons by the four feet, and 7J tons by the three feet 

 drain. No springs affected the result. Hence we have two 

 phenomena very satisfactorily disclosed first, that the deepest 

 drain received the most water; second, that it discharged the 

 greatest quantity of water in a given time, the superficial area of 

 supply being the same to both drains.&quot;
