Dwight A. Webster and John McDonald are both passionately dedicated fishermen and students of the literature of angling. In engaging themselves to bring to life Berners' trout flies for publication, they took on a venture never before attempted. At first they divided the work. McDonald, author-editor of The Complete Fly Fisherman, was to organize the research in the U.S. and England, and draft the story. Dr. Webster, professor of fishery biology at Cornell University, was to analyze the entomology, real and fanciful, and tie the flies, in all of which matters he is one of the nation's foremost experts. But, as often happens in a successful collaboration, before they got through exchanging drafts and talk, neither was able to say who had done what.
