 Whitewater larger than three pounds in weight, but the Black

 appending a short history of the Black Bass that I wrote for 

 the Fish Culture Association, and also a letter of my pisci- 

 culturist, Mr. Walter Silk, on the subject of his breeding and

 of this fish in the younger species is greenish- black or dark 

 olive-green, darker on back, and shading to yellowish-white on
