A young grainer ought to keep a sketch-book always in his pocket, and wherever he sees a fine bit of work, make a careful drawing with his pencil of it; he will thus be able to get variety in the markings of his wood. He ought also to practise constantly when he is at home on a panel with his thumb-nail at _rat tails_, so as to get dexterity and grace, because there is a vast amount of freehand drawing required in this portion of the work. The first thing he has to study is the composition of that panel; the large markings come first. Here he may linger tenderly for a time with his rag-covered nail wiping out square, oblong, and round patches, and softening and half cleaning out parts with his narrowest and finest toothed comb, also rag-covered. At this portion of the work the true artist comes in with his manipulations, like the manipulations of the etching printer with his ink on the plate; and I am positive that if John Ruskin had but tried to copy a piece of real oak with the same tenderness and patience with which he has so often copied old masters, he would never have dared to decry the art of graining. As in etching, perfect cleanliness and an unlimited supply of white, well-worn rags are indispensable to a grainer if he wishes to succeed in his art; yet, as the professional grainer is generally a dashing-looking fellow with artistically long and bushy tresses and Vandyke beard and moustachios, the maid-servant's heart generally succumbs to his charms before even he has unpacked his traps, so that he is not at all likely to run short of clean rags during his campaign. If any of my readers will take up and examine a piece of polished oak, they will be surprised to see what a multitude of strange devices there are in it; cabalistic signs and figures which are for ever varying as they shift about in the light; strong markings in places, with a crowd of slender flourishes trailing away from the bolder designs. These slender flourishes are vulgarly termed '_rat-tails_.' Now, to comb a panel properly requires some practice and taste, but to be able to wipe out these rat-tails requires a great deal of practice and a greater degree of discretion, so as neither to crowd the panel nor make it appear meagre; the bolder figures with the softened parts require about as much real talent as is expended upon making an original sketch from nature, and a great deal more than would be wanted over the copying of an old master. The comber and rat-tail draughtsman might easily qualify himself to copy an old master, but the adroit inventor of the bolder '_champs_,' which occupy the centre of the panel, is already qualified to produce a monochrome direct from nature; if gifted with the colour-faculty, and if his power of making these 'champs' prove that he has mastered form, he might aspire to any height on the artistic ladder.
