hundred and twenty-three small eels, the same size as the ones 

 taken in the early spring of the previons year. On this date, 

 May 9th, I also put a trap in the overflow with the opening 

 facing down stream to intercept eels that might be coming up 

 into the lake. 



May iTtli this trap was examined and found to contain 

 eighty-'nine small eels, thirteen small trout, one snutll sucker, 

 and one minnow. On the same date onlv eigbte-en small eels were 

 taken from the trap in the gate-house. 



June 1st sixty-six small eels, ten small trout, and four

 two ways that my theory was correct, and that the small 

 eels talvcn in the early spring of 1904 had just reached the lake. 

 A confirmation is found in the fact that while the two traps 

 were in use, the trap in the stream stopped nearly all that were 

 going into the lake, so that there were only a few to get into the 

 trap in the gate-house. 



The trap in the overflow stream was taken out June 1st, 

 1905. 



June 9tli, six eels were in the trap in the gate-house; 

 June 24th, 2 were taken. Oct. 6th, 5 were taken.
