JOHNSON, HABITS OF A CLIMBING CATFISH 333 



channel below. A day or two after the water had thus been diverted, a 

 dozen or more of these fish were observed to be clinging to the rock at 

 the foot of the fall at the end of the pipe. They were evidently on their 

 way up stream, but had encountered an artificial condition that inter- 

 rupted their further progress. They were nosing about in search of a 

 small stream or film of water sufficient to keep their gills wet and to lead 

 them to the main body of water above. As there was no such stream, 

 their further progress was prevented. They made no observed attempt 

 to swim up the fall, but confined their efforts to making short excursions 

 up the rock above the water. Failing to find any leading stream, they 

 crept back. 



They deposit their eggs in the deepest pot-holes and attach them indi- 

 vidually to the under sides of large rocks.
