30 white paper must be the substitute for white colour. There are many persons who profess to sell what they call permanent white, but it is so little to be depended upon, I should not recommend its use, but rather to leave the paper where white is required. An important rule to be observed is, that whatever be the colour of the flower you are painting, the lightest tint is to be laid in first; then touch in the next tint, and according to your pattern darken the shadows. In doing this particular care must be taken to soften the edges of every tint, so that they may lose themselves in one another. This will make your drawing appear soft. One means of doing this will be to be careful not to have the second tint too dark, and with the point of another pencil just wetted, soften the edge of the second tint; but this is one of the few difficulties that must be got the better of by practice. It is hardly necessary to say, that the tints should be tried on a piece of waste paper previous to laying them on the drawing. In several of the first following plates I have selected a variety of such flowers as will be most easy to copy from, which will prepare the practitioner to attempt the larger and more difficult ones with better success. In many of the small flowers there will be found only three tints. The yellow crocus in the first plate is laid in with gamboge. The first tint of shade is rough terra de siena, the darkest tint is burnt terra de siena. This shews the effect which may be produced by three tints only; the purple crocus and all the small flowers in the corners of this plate are finished with three tints. As all these are very easy to copy, I should recommend the copying them repeatedly, as it will prepare them better to attempt the next plate, the flowers in that having four tints in some of them.
