The Art of Graining is judged by the authors of this treatise to be of sufficient importance to justify a work devoted especially to the task of giving instruction to learners of the art.All graining is an imitation of some more or less well known wood, and the learner may doubtless draw from nature the copies he desires to imitate; but it is only trained skill that can accomplish the task perfectly, and it is presumably true that those who, in acquiring a long experience, have made the obstacles to success a special study, are best prepared to afford instruction to a beginner.The authors of the work present here the result of a long experience in the practice of this decorative art, and feel confident that they hereby offer to their brother artisans a reliable guide to improvement in the practice of graining.It is earnestly recommended by the authors that learners should practise drawing the several copies given as samples, with drawing pencils, using both narrow and broad-pointed, as the surest means of acquiring such thorough mastery of proper manipulation as will insure the highest degree of success.It is believed, moreover, that experienced learners will find it not amiss to avail themselves of the methods set forth in this treatise, affording as they do, the sum of the examples of fellow-artisans who have carefully 4 studied nature's own modes, and have studiously followed such plans in working as insured the closest and most durable adherence to the original form and color.CHARLES PICKERT,A.
