Report on the Agricultural Implements at 
ribbed, and its action consists in passing the seed down into the mill with re- 
gularity, and in arresting the passage of stones, nails, or other substances likely 
to injure the machine. These foreign matters become wedged between the 
feed-roller and the hopper, and cause the belt, which drives the roller, to slip, 
until the obstruction is removed. The seed, after passing the feed-roller, 
passes by the shoot D to the mill proper — which comprises a hulling-wheel, E, 
and certain adjustable knives, F, F, F, in the concave shell. The wheel 
is made of notched and ribbed sections, and it is due to the action of this 
surface in rapid revolution, in conjunction with the fixed knives, that the 
shell is removed. The sections are so arranged on the surface of the wheel, 
as to act like a screw ; they can be regulated to compensate for wear. The 
shell and seed fall through the passage G, on to a fine reciprocating screen, 
above which is a revolving spindle, furnished with wooden teeth : these teeth 
keep the mass thoroughly stirred, separate the seed which passes through the 
screen, whilst the shells and cotton are ejected from the end of the shoe. 
The hulled seed is then received into the box screen I, which, being shaken 
by suitable mechanism, separates the still remaining light portion of the 
hulls that have passed through the meshes of the wire screen, and carries 
these portions out over the apron J, while the cleansed seed passes through 
the opening K. This machine, which is capable of hulling from 15 to 20 
bushels an hour, costs 150 dollars, retail 211. 10s. 
Winnowers. — In the French section, Monsieur Joseph Pernollet showed 
revolving screens both for grading corn, and for removing cockle-seeds, the 
former by having the screen divided into sections with different sized openings, 
and the latter by an ingenious arrangement of the internal surface which is 
indented with round holes of such size as to hold the cockle-seeds, which are 
thus carried round, until they fall by gravitation into a curtain, and from 
thence by an Archimedean screw are delivered at the end, the grain coming out 
below. This is not a new device, indeed, so old is it that I believe the original 
patent has lapsed, and a similar machine was shown by German exhibitors, 
Mayer and Co. ; but whereas M. Pernollet's machine comprises simply a 
hopper and revolving screen, the latter driven by gearing, Messrs. Mayes 
and Co.'s designs are more ambitious, including a separator, winnower, re- 
ciprocating screen and a force-feed. The revolving screen is driven by strap- 
gear. The construction is decidedly inferior to the French machine. The 
Americans retain the old form of box winnower, some of the best machines 
having very efficient arrangements for the separation of weeds and the grading of 
the corn. This is the more necessary inasmuch as the most complete threshing- 
machine has only a single winnower, and there is scant opportunity for the 
separation of weed-seeds, in the rapid passage of the corn after it has been 
winnowed to its exit from the machine. The Queen of the Harvest Company, 
West Chazy, New York, provide an excellent winnower, which is described 
as the Queen of the Harvest Grain and Seed Separator and Grader. This has 
a detachable hopper or feeder, which can be actuated by a lateral smooth or 
trembling motion, according as smooth rollers or cogs are inserted. The feeder 
can be raised or lowered ; it has two screens, one above the other, the first 
with coarse holes lets the wheat through, and grades larger material. This is 
useful in the event of dirt or stones, pieces of wood, &c, being present. The 
sieves, which are numerous and of great range, are made of steel wire sewed 
on by hand. The screen frame has a trembling motion similar to the feeder, and 
due to the same mechanism, viz., a rack on the underside working in a friction 
cog-wheel. The angle of the sieves can be altered. A mixture of wheat, 
oats, barley and seeds was operated on, and a successful division made. The 
price varies from 35 to 75 dollars, according to the number and grade of the 
sieves. Barnard Corticle, of Norwalk, Ohio, also showed a good winnower. 
The shoe is hung on steel springs, and has a good shaking motion. This is both a
