It is related that once upon a time Murillo had been well entertained by an abbot, and in returning his thanks for the hospitality received, he expressed his regret that he had no canvas with him, otherwise he would have repaid the kindness with a picture. The abbot at once presented the painter with his own table-napkin, and told him to use that, which Murillo did, producing in the same day a picture which for richness and effect he never himself surpassed.

I will not say that Murillo did not use that napkin as a canvas: I only assert positively that he never painted that picture upon it the same day, for the simple reason that it would have to be primed, either with distemper or oil, and receive several coatings, each coat requiring to dry, be smoothed down, and recoated before ever he started painting, even if a stretcher was not made for it. He may have painted the picture in one day after the napkin had been prepared, but I venture to say, without fear of contradiction from any practical artist-colourman, that Murillo was the guest of that hospitable abbot for several days after the napkin had been presented to him.

Although that autocrat of art, John Ruskin, has declared vehemently against the imitation of woods and marbles as an art, yet as a protest against his hasty and unprofessional verdict, and as one who has spent years in acquiring the art and teaching it afterwards to my house-painter students, I now take up this subject as a very important one, and will try, as far as a practical teacher can put them upon paper, to give a few of my own methods in this branch of art, for the sake of those whom it may concern.

Let me suppose that my readers are students and young house-painters or amateurs, who have not had the opportunity of getting instruction in this highest branch of their trade. I suppose, however, that they know enough of the preliminaries to be able to prime and prepare their panels, and have made them all ready for the purpose of trying to grain upon them.

THE ART OF OAK IMITATION—OAK GRAINING

We will take oak first, as it is the most generally used in the business, as well as one of the hardest to master, although as an imitation it is more mechanical and less truly artistic than any of the other imitations.

The ground required for oak is buff colour, either light or dark, according as the age of the wood is intended to be represented. To make this light tint, a little yellow ochre, with white lead, drier, oil, and turpentine, are all that are required; while if it is very new wood, the ground should be the colour of rich cream; if old oak, the ground colour can be darkened according to taste with Roman ochre, light red, and burnt umber.

One precaution must be strictly observed if the grainer wishes to produce clean work, and that is, to be sure that his ground is perfectly firm and dry before he begins, so that this ground is not likely to be torn or rubbed off with the combing or veining. I like a ground to be dry but not too hard or oily, as when dry, but soft, it will produce more feeling work, particularly if the grainer is using the most useful of all his tools, the thumb-nail.

A grainer’s thumb, like a miller’s, has a great deal to do with the making of sham oak; therefore you may easily distinguish a professional oak-grainer by the length, strength, and tender care which he lavishes on his thumb-nail. It ought for this purpose to be kept long, and carefully rounded and smoothed.

The tools required for this work are a box of assorted combs, two or three pieces of soft cork cut with notches, plenty of soft cotton or linen rags, and that properly trimmed thumb-nail. He will also require for oak-over-graining the same brushes which he uses in the soft woods; camel-hair softeners, grainers and over-grainers, with wipers-out and sash-tools, &c.
