 green. I don't know what the fish look like when they 

 reach you, but they have lost their royal coloring before 

 they leave here. 



Mr. Lewis has just told me of an entirely new variety 

 of trout that he catches in the lake, at a depth of from 80 

 to 100 feet. He takes them on set lines, which he places 

 out over night, and says he has never been able to catch 

 one of this species in any other way. He says it differs 

 from any other trout in the lake ; that it is a long, slender, 

 graceful and very attractive fish, with a grayish green 

 back and below the median line, pure white sides and 

 belly. He has promised to secure a specimen of this 

 variety for me to be sent to you.
