Spread over the slab or mantelpiece a thin and carelessly mixed blending of the black, white, and medium, so that when it is covered the ground shines generally through that scumbly coating with portions all irregular; then take a long studying look at your work, and with your sash-tool put in the dark grey portions loosely, leaving the covered ground for the light as you might if painting a picture; rub in your larger masses roughly; soften these off lightly, and next proceed with a feather smeared with white to put on your light veins; again soften with your hog-hair tool, and with another feather, dipped amongst the black, make dark veins, crossing light and dark where needful, until the effect is all filmy and delicate.

Finish off with little touches and flecks of black and white on your feather-tips, so as to produce stronger veins, remains of fish, shells, and the other fossilised life with which this marble is crowded.

The Italian marbles, such as sienna and other varieties, are done in a similar way, with the difference of colour. All marbles, with the exception of the first working of black and gold, are worked in oil-colour, although, of course, as in wall-papers, they may be worked, after a style, in body colours, and when done in distemper they are finished off while the colour is wet.

Granites may be imitated either by sparking the colours on by striking the charged brush lightly with a stick, or else dabbing them on with a sponge; a nice blending of the two methods produces the most natural effects.

I often pass painters producing on shop fronts marbles of green, blue, and red, which, although pretty, represent no earthly stones. I have stopped to ask them what they were making, but they could not classify it or give it a name. They had learnt to work from other grainers, and never paused to inquire what they were producing. Many of these grainers never studied a piece of real marble in their lives, and possibly would not like the sober reality if they did come across a specimen or so in a museum. The subtleties and time-markings would mean nothing to them, in the same sense that a real bit of Nature would not appeal to the man who had spent his efforts in copying flashy oleographs.

Now, this sort of graining is very abominable to me, as I dare say it would be to John Ruskin, or any other diligent searcher after truth.

Every grainer ought to know where the specimen he is imitating or reproducing comes from, and what has caused those veins and markings which he is putting in; then he will be able to instruct the masses and satisfy the botanist and geologist: for as he paints he will be preaching a sermon on the stone, and writing out a record of the world’s history before man came on the scene. He will not then put meaningless figures into his marble, but every flick and curl of his feather will sketch in the broken remains of an extinct race: and in this way we distinguish between the artist-grainer and the unreasoning mechanic.

Alma Tadema has shown how an artist can imitate marble, in his Roman masterpieces, by his care and tender manipulation. He has raised the art of the grainer to a very lofty pedestal indeed. In the Royal Academy Exhibition, where crowds gather round his antique revivals, it is not so much the noble Roman men and maidens who force the cries of admiration from them, as the broad spaces of white and coloured marbles which predominate in these compositions; those time-stained, rusted blocks, with the slight suggestion of a flaw here and there; the iron-stains showing through the subdued lustre of the Roman limestone; the polished pillars and inlaid floors all kept under control, with the veins offered only as an apology at rare intervals. This art of fidelity to nature and rigid restraint have made him the grand master-grainer of the age.

And yet I have seen as fine specimens of imitation marble as ever Tadema produced on his canvases wrought upon a show panel, only that I have not seen the same masterly modesty and restraint. The producer of the show panel, as a rule, exerts himself too much, and attempts to put into one panel the results of a whole palace, and that is the mistake which makes his work appear superficial and unreal. Alma Tadema puts no more work in his slab than what appeared in the slab he copied so literally, because he never permits his imagination to run away with him, while he has nature to guide him, and that is the secret of his wonderful success.

And this example I would impress upon every grainer, young and old, who may aspire to produce something great in his own line of life; for the work on a door, a dado, shutter, skirting-board, or mantelpiece, is of as much importance as the fresco on the plaster above—those frescoes which have been the pride and glory of the best of our old masters.
