Mi 
be taken not to over-feed it, otherwise 
part of the flour will pass with the bran. 
Occasionally, perhaps once in two or 
three years, according as the machine 
may be more or less used, the brushes 
will want raising about the twentieth 
part of an inch, which may be done by 
unscrewing and taking out the half cir- 
cular pieces of wood at cach end of the 
cylinder, marked 4 and 3, and the top” 
brass at the front of the machine which 
confines the axle, The cylinder, axle, 
aud brushes, will then lift out together, 
and the brushes may be raised a little at 
each of the screws which confine them to 
the axle; be careful not to raise them 
too much, as the machine will in that 
ease go hard; more or less descent may 
be given tothe machine, by lowering or 
raising the hind legs, according as it may 
be found to work best. It is immaterial 
which way the windlass is turned; it 
will be found best to turn it sometimes 
one way and sometimes the other, the 
brashes by that means will wear regularly. 
Keep the spindies and cog- wheels moist 
with neatsfoot or sweet oil. By making 
holes through the bottom of the drawer 
about five inches wide, opposite to 
where the fine and coarse flour, sharps, 
&e. fall from the cylinder, sleeves (as 
the millers term them) may be attached 
ateach hole, through which the different 
sorls may be conveyed into sacks 
through a floor, if not convenient to 
elevate the machine to the height of a 
sack. By this means the time and 
trouble requisite to empty the drawer, 
may be saved. The fine and coarse 
flour may be conveyed into separate 
sacks, or both sorts (regularly mixed) 
into one sack, if but one sort of flour is 
wanted. 
In November, 1818, six of Mr. 
Parkes’s steel mills were put up in the 
poor-house at Birmingham for the pur- 
pose of grinding wheat, also a dressing- 
machine to dress the flour. From Sep- 
tember 16th, 1820, to March 2st, 1821, 
the operation of the grinding-mills conti- 
nued to be favourable, the result of the 
stock-taking proving highly satisfac- 
tory; 939 bags of wheat (vine score 
cach) were ground, producing 474 sacks 
of good flour; thus the accustomed cal- 
culation of two bags of Wheat producing 
one sack of flour was exceeded, and the 
Joss in weight was found to be considera- 
bly less than what is alowed in grinding 
with stunes. The people employed at 
these mills are chiefly out-poor: they 
are paid every evening what they have 
_eamed in the course of the day; they

have 2s. per bag for grinding wheat, and 
three meu at one mill will grid two 
bags in about six hours, which is 1s. 4d. 
to each man. The dressers have 10d. 
per sack for dressing the flour. The 
bran which comes from this first dres- 
sing is ground over again, and is again 
dressed, and the flour obtained from this 
second operation is mixed with the first, 
and makes very excellent bread ; 1s. 3d. 
per. cwt. is paid for grinding the bran, 
and 4d. for dressing it. The whole of 
the flour is consumed at the workhouse 
and asylum, and the bran and sharps (or 
pollards) are sold at a wholesale price. 
A profit is now obtained after paying 
all expenses, viz. rent of premises, wages 
of the persons who superintend them, 
repairing the mills, &c. A wheat-mill 
would last a family of twelve or four- 
teen persons two or three years before it 
would want re-cutting, after which it 
would be as good as new; and, as it 
would bear re-cutting three or four 
times, it would endure eight or ten 
years. The machines, if kept in a dry 
situation, are still more durable.
