In issuing this second treatise on Crayon Portraiture, Liquid Water Colors and French Crystals, for the use of photographers and amateur artists, I do so with the hope and assurance that all the requirements in the way of instruction for making crayon portraits on photographic enlargements and for finishing photographs in color will be fully met. To these I have added complete instructions for free-hand crayons.
This book embodies the results of a studio experience of twenty-four years spent in practical work, in teaching, and in overcoming the everyday difficulties encountered, not alone in my own work, but in that of my pupils as well. Hence the book has been prepared with special reference to the needs of the student. It presents a brief course of precepts, and requires on the part of the pupil only perseverance in order that he may achieve excellence. The mechanical principles are few, and have been laid down in a few words; and, as nearly all students have felt, in the earlier period of their art work, the necessity of some general rules to guide them in the composition and arrangement of color, I have given, without entering into any profound discussion of the subject, a few of its practical precepts, which, it is hoped, will prove helpful.
