have absorbed most  water,  i.e.,  the  high-lights,  will naturally
                 refuse to take the greasy pigment more than those parts which
                 have not absorbed much water,  i.e., the shadows.  With a strong
                 subject the picture should  still be  visible in a faint brownish-
                 grey tone.
                     A little of the pigment is now taken up on the tip of an old
                 thin table knife, which should be kept for the purpose, although
                 a proper artists' palette knife would be better.  This is smeared
                 on the palette, and if the ink is very stiff a little of the megilp is
                 smeared with it.  The largest pigmenting brush is taken and held
                 between the thumb and the two  first fingers of the right hand.
                 To arrive at the correct method of holding the brush, pick it up
                 halfway down the handle and hold it lightly in the same position
                 that you would a pen or pencil for writing or drawing.  Then
                 tilt it in the fingers so that, instead of the wooden end pointing
                 back over your shoulder, the handle becomes vertical, with the
                 head of the brush pointing straight down.  The thumb should
                 be straight and at right angles to the shaft of the brush, the first
                 finger slightly bent, and the second finger nearly straight.  The
                 brush should not be gripped by the fingers, but held poised in the
                 finger tips.  This, with slight modifications, is the correct position
                 in which to hold the bromoil brush, coupled with the slight forward
                 dabbing action that is assisted by the hoof-shaped cut of the brush
                 itself.
                     Dab the brush on to the smear of pigment on the palette, and
                 keep on dabbing until a level tone has been produced on this part
                 of the palette.  Do not dab too hard — just a  "  pecking  " action
                 that will enable the extreme tips of the hairs to get well covered
                 with pigment.  After dabbing for a little while,  it will be found
                 that the ink which was spread on the palette has been largely
                 taken up and evenly distributed over the surface of the brush.
                 Now  start pigmenting  the print  with the brush fully charged.
                 Choose a portion of the subject which you know contains a shadow
                 in juxtaposition with a high-light, and pigment just at this spot.
                 If the bleached print is in proper condition, the ink of the right
                 consistency, and the dabbing action correctly performed,  it will
                                            118
