[1] Floating Flies and How to Dress Them provides an in-depth study of nearly 100 duns and spinners in the English chalk streams of Hampshire County.

Included is information on types of hooks and implements to use, plus tips on dyeing materials and how to dress the flies on eyed-hooks.

The book contains ten colorplates and many black and white line drawings illustrating specific techniques.

It was Halford's work that inspired M. Albert Petit to write the book that re-introduced and popularized fly fishing in France.

Halford's scrapbook contains twenty-seven review notices, in which positive and gratifying adjectives abound: 'Practical, and at the same time delightfully-written', 'Thorough, clear and interesting', 'His almost unequalled experience', 'A real treat to get a book so plain and purposelike, and so beautifully got up in all respects'.
