The developing bench is 18 in. wide, and in the middle an opening,
9 by 11 in., is cut, below which is fixed the sink. It is shown in
detail in Fig. 7, and should be zinc lined.

The zinc should not be cut but folded as shown in Fig. 8, so that
it will fit inside the sink. The bench at each side of the sink
should be fluted (Fig. 9), so that the water will drain off into
the sink. A strip should be fixed along the back of the bench as
shown in Figs. 6 and 9, and an arrangement of slats (Fig. 10),
hinged to it, so as to drop on the sink as in Fig. 6, and shown to
a larger scale in Fig. 11.

A shelf for bottles and another for plates, etc., can be fixed
above the developing bench as at D and E (Fig. 6) and another as F
in the same drawing. This latter forms the bottom of the tray
rack, which is fixed on as shown

in Fig. 13. The divisions of the tray rack are best fitted loosely
in grooves formed by fixing strips to the shelves and under the
bench and sink as in Fig. 13.

Extra bearing pieces will be wanted for the shelves mentioned
above, these being shown in Fig. 14. The window is formed by
cutting an opening in the side opposite the door, and fixing in it
a square of white glass with strips of wood on the inside and
putty on the outside, as in Fig. 15. A ruby glass is framed as
