The information offered in another thread kind of peaked my interest. Let's see how many of you (of course I include myself) are willing to take up a challenge to investigate, identify and post here the first article or essay you can find that was written in a: book, pamphlet or magazine that describes the proportions of a Catskill Dry Fly. Specifically, you must cite the reference, by title and date, the author and the proportions.
Anyone up to this challenge?
