MR. COOPER'S EXPERIMENT AT BALLISODARE. 263 



saw four fish at the upper step jumping together. On the 

 10th again at Collooney. Not nearly so many fish 

 moving this day ; counted at upper step nineteen in five 

 minutes. Turned off the water, and put up 256 fish. 

 This day (11th) counted 102 fish jump at the upper step in 

 five minutes. Turned off the water; the pond actually 

 alive with fish, in general larger and fresher from the sea 

 than those of yesterday. Put up 246 fish, and then 

 stopped as the fish were getting sick in the pond. I am 

 confident that we did not take half the number out, and 

 that we left from three to four hundred in the pond.' "
