for staining. It will be readily perceived that there is no fixed

with any degree of certainty. In order to arrive at the best results,
the stainer is recommended to observe the following rules:--

All dry stuffs are best reduced to powder, when it is possible, before
macerating or dissolving them.

All liquids should be strained or filtered before use.

The requisite ingredients should always be tested before a free use is
made of them, as the effect produced by a coat of stain cannot be
accurately ascertained until it is thoroughly dry.

Amateurs in staining had far better coat twice or thrice with a weak
stain than apply a strong one; for if too dark a tint is first obtained
it is often irremediable. Flat surfaces will take stain more evenly if a
small portion of linseed-oil is first wiped over, well rubbed off, and
allowed to dry, then lightly papered down with fine glass-paper. End-way
wood which is of a spongy nature should first have a coat of thin
varnish, and when dry well glass-papered off. For applying stain a flat
