154 BAYS OUT OF DOORS.

 thought they did, an enemy in me. 



I had had a very different experience recently, with an 

 old sunfish and her brood, and so wondered the more at 

 the exceeding wildness of the little minnows in the pond. 

 "While gathering snail-like shells from the leaf -stalks of 

 the lotus, this troubled mother fish was much exercised 

 because her brood had no fear, and were in danger of 

 being trampled upon, as I waded in the shallow water. 

 Then, prompted by an innate love of teasing, I put my 

 hand into the water, and the young, instead of darting 

 away, clustered about it and nibbled at my fingers. The

 scooped in a near-by ditch until I caught a fish of about 

 the size of the parent of the brood, and then separating 

 the young from their mother and keeping them well apart, 

 set my captive free among the former. Instantly there
