t effects in the
adjacent squares or rectangles are due to precisely the same reasons as
those explained in connexion with the ground and the figure of damasks.
The same weaves are used in both damasks and dices, but simpler weaves
are generally employed for the commoner classes of the latter. The
effect is, in every case, obtained by what are technically called warp
and weft float weaves. The illustration B shows the two double damask
weaves arranged to form a dice pattern, while A shows a similar pattern
made from two four-thread twill weaves. C and D represent respectively
the disposition of the threads in A and B with the first pick, and the
solid marks represent the floats of warp. The four squares, which are
almost as pronounced in the cloth as those of a chess-board, may be made
of any size by repeating each weave for the amount of surface required.
It is only in the finest cloths that the double damask weaves B are used
for dice patterns, the single damask weaves and the twill weaves being
employed to a greater extent. This class of pattern is largely employed
for the production of table-cloths of lower and medium qualities. The
term damask is also often applied to cloths of this character, and
especially so when the figure is formed by rectangles of different
sizes.

DIEBITSCH, HANS KARL FRIEDRICH ANTON, count von Diebitsch and Narden,
called by the Russians Ivan Ivanovich, Count Diebich-Zabalkansky
(1785-1831), Russian field-marshal, was born in Silesia on the 13th of
May 1785. He was educated at the Berlin cadet school, but by the desire
of his father, a Prussian officer who had passed into the service of
Russia, he also did the same in 1801. He served in the campaign of 1805,
and was wounded at Austerlitz, fought at Eylau and Friedland, and after
Friedland was promoted captain. During the next five years of peace he
devoted himself to the study of military science, engaging once more in
active service in the War of 1812. He distinguished himself very greatly
in Wittgenstein's campaign, and in particular at Polotzk (October 18 and
19), after which combat he was raised to the rank of major-general. In
the latter part of the campaign he served against the Prussian
contingent of General Yorck (von Wartenburg), with whom, through
Clausewitz, he negotiated the celebrated convention of Tauroggen,
serving thereafter with Yorck in the early part of the War of
Liberation. After the bat
