Fig. 34 is an illustration of various kinds and sizes of lead; showing
some with the glass inserted in its place. By all means make your leads
yourself, for many of those ready made are not lead at all, or not pure
lead. Get the parings of sheet lead from a source you can trust, and
cast them roughly in moulds as at fig. 35. Fig. 36 is the shears by
which the strips may be cut; fig. 37 is the lead-mill or "vice" by which
they are milled and run into their final shape; fig. 38 the "cheeks" or
blocks through which the lead passes. The working of such an instrument
is a thing that is understood in a few minutes with the instrument
itself at hand, but it is cumbrous to explain in writing, and not worth
while; since if you purchase such a thing, obviously the seller will be
there to explain its use. Briefly,--the handle turns two wheels with
milled edges 1/16 of an inch apart; which, at one motion, draw the lead
between them, mill it, and force it between the two "cheeks" (fig. 38),
which mould the outside of the lead in its passage. These combined
movements, by a continuous pressure, squeeze out the strip of lead into
about twice its length; correspondingly decreasing its thickness and
finishing it as it goes.

_Some principles of good taste and common sense with regard to the
cutting up of a Window; according to which the Cartoon and Design must
be modified._--Never disguise the lead line. Cut the necessary parts
first, as I said before; cut the optional parts _simply_; thinking most
of craft-convenience, and not much of realism.

[Illustration: FIG. 38.]

Do not, however, go to the extent of making two lead lines cross each
other. Fig. 39 shows the two kinds of joint, A being the wrong one
(as I hold), and B the right one; but, after all, this is partly a
question of taste.

Do not cut borders and other minor details into measured spaces; cut
them hap-hazard.

[Illustration: FIG. 39.]

Do not cut leafage too much by the outlines of the groups of leaves--or
wings by the outlines of the groups of feathers.

Do not outline with lead lines any forms of minor importance.

Do not allow the whole of any figure to cut out dark against light, or
light against dark; but if the figure is ever so bright, let an inch o
