In the preparation of this work it has been my aim to present Recipes, simple, yet complete in every detail, for dyeing every color and shade of color known. Reliability, practicability and rapidity I claim for this work, and would ask that it be judged not from a literary standpoint, but as a thorough and practical instructor in the art of Ostrich Feather Dyeing, as simplified and perfected by me during years of hard work and research. It is the first work of its kind ever put before the public in the English language, and will, in consequence, receive from those interested close scrutiny and criticism, which prompts the author to offer $1000 to any person who will prove that the recipes herein contained, or any single one of them, will not produce the desired color or shade perfect and in the time mentioned.
