Rh chrome yellow, with coach japan and turpentine to a proper consistency for grinding in the mill, approximating as nearly as possible the desired shade of green. When ground add a tablespoonful of raw oil to a pint of paint, and when well stirred together test its drying qualities by spreading a little on the thumb-nail and blowing upon it to hasten evaporation, if it dries dead add a few drops of oil or rubbing varnish, or if too glossy add turpentine until an egg-shell gloss is obtained.

This ground work or preparation coat should be put on with a camel's-hair brush as smoothly as can be, allowing no laps or brush marks to remain visible.

The black portions are next to be done, and this paint may be mixed in the same manner as the green, of lamp black or ivory black. When all is coated set the job aside to dry until the next day, at which time it should be well inspected and if any scratches or indentations are found, soft dark putty must be used to fill them, then rub over gently with No. 1 sandpaper, partly worn, to prepare it for the color proper, dark green and ivory black. The dark green may be made as follows:

Pulverize, on the stone, some Dutch pink, and mix it with half and half japan gold size and turpentine and grind it fine. Then mix in the same manner some Prussian blue and grind it into another cup. Now, little by little, add the blue to the Dutch pink, stirring it constantly, until the desired shade of green is obtained, and temper the mixture with raw oil in the same manner as explained for the ground coat. Apply with camel's-hair brush. The back parts may now receive another coat of ivory or drop black. If ready-mixed colors are used, instead of mixing them as above, take royal green for the green parts, and jet black for the black portions, tempering them as described with oil.

It is the usual custom to make color-and-varnish by adding to a partly filled cup of varnish a little color, but it
