No. 20 Drag or Extra Spanish
To do which you must have a trough twice the length of the sheet of paper; as, in order to produce the elongated form of spots, you will have to drag or push it from one end of the trough to the other in the course of laying down the sheet of paper. The colours and preparation are the same for this as for the other Spanish, only the colours are used considerably thinner, as they would get so thick upon the paper, from one sheet being drawn over and taking up a surface of colour usually allowed for two, that it would peel and crumble off and not burnish.
