NEW SrYLE or CARrErs-Mr Whitlock, near
Edinburgh, Scotland, has invented a process
whereby Brussels, and Wilton, and other expen-
sive kinds Of carpets, are made much cheaper
than heretofore, while at the same time, a more
durable article is produced, and the most gorge
Gus patterns introduced, with scarcely any limi-
tation Of colors. At one factory there are two
hundred looms at work on this principle. The
principle is said to be in printing first the yarn,
and weaving it by q mathematically correct pat
tern soon after the pattern Of the print. The
least bagging in the warp or weft therefore will
spoil the beauty of the web.
