he different values were produced literally
"while you wait." Under such circumstances it is not surprising to learn
that minor varieties are very numerous.
In printing from typographical plates the ink is applied to the surface
by means of a roller. Impressions from these plates, before they have
been pressed, show the design forced into the paper, instead of raised
above it, as in _taille douce_ printing.

There is often a noticeable difference in the impressions made from the
same plate by different workmen, owing to the varying degree of skill
and care employed. We frequently find in stamp catalogues such terms as
"London print" contrasted with "local print." These terms indicate a
fine impression and an inferior one. We find a good example in two five
cent stamps of the Confederate States. They are both from the same plate
but the first was printed in London by the skilled workmen of Messrs. De
La Rue & Co., and the last was locally made with poor facilities.
Embossing is a variety of printing connected with both line engraving
and typography. Embossing dies are produced by sinking lines in the
plate but, as a rule, they are intended for such productions as stamped
envelopes and the sunken portions are a series of hollows rather than
sharply cut lines. An envelope, viewed from the reverse, will give an
excellent idea of the appearance of such a die. In printing from these
dies very heavy pressure is used and the paper usually is backed by a
piece of leather or something of similar nature. In its simplest form
embossing is a stamping in relief without color. The stamp of Natal
shown here was produced in this manner. The stamps of Scinde, issued in
1850, were embossed and for the red one large wafers, at that date in
common use for sealing letters, were used. The brittle nature of this
material is probably responsible for the scarcity of this stamp,
especially of copies in fine condition.

Embossing is usually combined with typography. The surface of the die
being inked, that part of the design is printed in color at the same
time that the rest is embossed. These three stamps show this class of
work, one being
