How to Fill the Brush with Pigment.—Now you must note that this is a heavy powder floating free in water, therefore it quickly sinks to the bottom of your little "pond." Each time you fill your
brush you must "stir up the mud," for the "mud" is what you want to get in your brush, and not only so, but you want to get your brush evenly full of it from tip to base, therefore you must splay out the hairs flat against the glass, till all are wet, and then in taking it off the palette, "twiddle" it to a point quickly. This takes long to describe, but it does not take a couple of seconds to do. You must have the patience to spend so much pains on it, and even to fill the brush very often, nearly for each touch; then you will get a clear, smooth, manageable stroke for your outline, and save time in the end.

How to Paint in Outline.—Make some strokes (fig. 20) on a piece of glass and let them dry; some people like them to stick very tight to the glass, some so that a touch of the finger removes them; you
must find which suits you by-and-by, and vary the amount of gum accordingly; but to begin, I would advise that they should be just removable by a moderately hard rub with the finger, rather less hard a rub than you close a gummed envelope with.
Practise now for a time the making of strokes, large and small, dark and light, broad and fine; and when you have got command of your tools, set yourself the task of doing the same thing, copying an example placed underneath your bit of glass. You will find a hand-rest (fig. 21) an assistance in this.
