tabletop ard o;her ornamental work, ere now pro-
du ed at Sa,ing.on IN great perfection. The English
p,roducers Of tbs art who established themselves %
Massachusetts,, used many aItifces to MAINTAIN
MONOPOLY, omorg which was that Of repreeen.rg he
American slate as breaking down under the heat OF
the eramelpg furnace and that they were therefore
eoupeled 10 import their slabs direct from Wales, %
that material would stand fire willie ours wsrd not.

But the great drawback under which the bosineseef
manufacturing school states at present ahors eorss~
in the crude and primitive character OF the machinery
and tools employed. Begun IN Wild AAssEicf, Away
from smith shop, all the appliances Of The fsc-
tory rude cheap and often inefficient, rendering
the production Of really fniehed srtcle impossible.
The Of material atevery tern s absolutely fright
fu At the quarry may be seen thousandsof lcats Of
perfect material all wasted in the sloves]y ppscsn 10
vogue Of taking it from the quarry and redaeugt 20
manageable size. II Is grievous to wiinsss tns de-
..ruc,ive marner in which this besutIfm materials
knocked 10 pieces by the rough en who frss remove
It from its primitive restug place. An nseasSes ran
would find no difficulty IN saving at cost ere hNf OF
all that is taken out. This saving would sessstnts
reuuperatng profit OF itself. Then in the smoothing
OF the slate preparatory 20 framing, there's oppon-
nifty to make a second saving equally great. The
clumsy drawing knife should ba bsnshed, and q mo-
chine constructed TO be driven by power, for shaving
the slate. Any one who viii examine an Ergish tlate
can see upon s surface the mark Of the tool by which
il has been shaved in machine IL is true, he En-
glish slate is harder than ours and able 10 wit as.and
heavier strain unbroken, but ours is nevertheless
sbundanty hard enough. An immense economy
could be introduced into this branch Of the business,
beside securing complete uniformity IN he product.
Then in the saving of the frames, cutting the grcoves,
and smoothing of preparatory 70 packing ap very
great improvements could be made. The whole ffsnsc
should be smoothed off by machine at one operation.
In fact in all these departments there should be stos
re, outon made. Strip the manufacture Of The crude
appliances with which il is carried on, anu 'epmcs
them with improved machinery especially aaapted 70
lis various processes, and the sum OF al he savings
thus secured would make the business generously re-
muneratiye The country can no more DO wthow
school states than without cotton shirts and he VINO
takes hold of the matter determined TO regeuerate tho
business, will find ii TO reward him well It is now
its original crudencss holding ont the strongest temp
tations for ingenious men TO grapple with ana over
come its numerous deficiencies.
