next two light blue ; the hackle light blue instead of jay ;
silver thread ; the joints being separated by black ostrich instead of peacock herl. The Colonel says of this fly ' So called from the feathers of the Indian crow in the body. I tried this fly for the first time about five years ago, and have killed with it and the Butcher, No. 3, more and larger fish than with any other ; a deadly fly in any river on which I have tried it.'
