ing-machine, or introduced by the taste of differ- 
ent manufacturers or the ingenuity of different 
improvers, is now par excellence the winnowing- 
machine of almost all Scotland, and of a large 
part of England. A full and minute description 
of one of the best ordinary varieties of Elmey’s 
machine, therefore, will substantially serve as a 
very satisfactory account of the whole of this 
class of implements; and such a description, ably 
and technically written, together with illustra- 
tive diagrams, lies happily at our hand in the 3d 
Volume of the Quarterly Journal of Agriculture. 
“AB and CD, fg. 1, are two standards of 
ash 3 inches square, and 4 feet long, with their 
fellows on the opposite side. These standards 
are fastened together longitudinally by a rail, 
one at each side, as seen at EF, also of ash, 3 
inches square, and 3 feet 11 inches long; inserted 
into GB and CD, 3 feet 2 inches from B and D; 
and transversely they are connected by ash-rails 
1 foot 9 inches long, and 3 inches by 2 in breadth,

at C,I,G, Hand B: thus a frame of ash is formed 
upon which the rest of the implement is con- 
structed. This frame is lined inside of the stand- 
ards, on both sides with thin fir deal, from C as 
far down as D; from A 11 inches below F to H; 
1 foot 2 inches from A to¢; and 6 inches from 
H to g. The large cast-metal wheel L, 2 feet 4 
inches in diameter besides the teeth, is divided 
into 6 segments, either of which are removable 
by screws for the purpose of repair; it contains 
144 teeth, and is fixed to an iron axle, both ends 
of which rest on brass lockers 6 inches long, on 
the rail EF, and its fellow. The shank of the 
handle M is 94 inches in the straight line; and 
the handle, a hollow cylinder of wood moveable 
round an iron spindle fastened at right angles to 
the shank, is 9 inches long. The shank screws 
on to the axle in the line of motion, as from M 
to H. The pinion N, also of cast-metal, 6 inches 
in diameter besides the teeth, contains 28 teeth ; 
is fastened on the end of the axle of the fans O;
