brooks was hailed as an omen of victory. Of course these little 

 fishes had really 'always been there.' They were there when 

 America was discovered and for a long time before, but the people 

 had not seen them. The warblers lived, you remember, in Spald- 

 ing's woods at Concord, but Spalding did not know that they were 

 there, and they had no knowledge of Spalding. So with the 

 Darters in Spalding's brooks. Still, when the day comes when his- 

 tory shall finally recount all the influences which held Indiana to 

 her place in the Union, shall not among greater things, this least of 

 little fishes receive its little share of praise? The Rainbow Darter 

 is a chubby little fish, as compared with the other Darters. In its 

 movements it is awkward and ungraceful, though swift and sav- 

 age as a pike. One of the mildest of its tricks, which we have 

 noticed, is this : It would gently put its head over a stone and 

 catch a water boatman by one of its swimming legs, release it, 

 catch it again and again release it, until at last the boatman, evi- 

 dently much annoyed, swam away out of its reach. It will follow 

 to the surface of the water a piece of meat suspended by a string. 

 It is more alert in discovering this than a hungry sunfish or rock- 

 bass, and it can be led around like a pet lamb by a thread to which 

 is fastened a section of a worm." — Jordan and Copeland.
