3Ions. Alfred Clcrt, of Niort (Deux-Sevres), France, showed a 
revolving cylindrical seed-separator, which is a modification of 
the machine introduced by Pernollet. The peculiarity is that 
the machine is in two distinct parts, which can be worked 
together or separately. The cylinders are made of sheet iron 
stamped with a number of indentations. The first portion has 
an arrangement for separating long seeds, such as oats, &c., 
which will not rest in the perforations, which are of large size 
so as to hold the wheat and round seeds, whereas in the second 
screen the perforations are much smaller, and therefore separate 
the round seeds, hareweed, (Sec, from the wheat. The corn is 
supplied from a hopper over a shaking screen into a tube. The 
shaking is produced by a steel spring acted upon by a small 
ratchet wheel on the driving spindle. The screens are driven 
from pulleys by 1-inch leather belting ; the grain not separated 
by the first screen is carried by a screw worm to the end of the 
machine, fails into the cups of an elevator, and is so raised for 
delivery into the second separator. The Judges carried out an 
experiment, taking a mixed sample of wheat, oats, vetches of 
different sizes, representing cockle seed, dust, &c., in all 1 bushel 
1 peck ; it took fifteen minutes for this quantity to pass through 
the machine, which equals about 5 bushels per hour. The work 
was excellent ; a perfect separation of dust and dirt (removed 
by a parallel screw about 9 inches long), oats, weed-seeds, and 
wheat having been effected. The latter on reaching the end of 
the second screen passes by a number of holes into an outer 
screen, sloping in the opposite direction, and is thus brought 
down to a box underneath. The separation was admirable, 
but the results as to quantity were not sufficient to justify a 
Medal. The price in the Catalogue is 10/. IQs. on rails, at 
Niort ; packing extra. The frame appeared rather light. 
The dairy exhibits of J\fr. Aklborn have already been noticed, 
and the poultry rearing and feeding appliances of M. Odile 
Martin, MM. Rouillier and Arnoult, and M, Voitellier, will be 
treated later on. , 
The Marquis of Riscal, Esti-emadura, Spain, exhibited a col- 
lection of extracts of green oak in a dry condition, as made by 
A. Pouriau, engineer, Paris, from raw materials obtained from 
the exhibitor's estate. Price 5Z. to 5Z. 18s. M. per cwt. It would 
be interesting to know how far these articles are available for 
general consumption. A collection of leathers and skins tanned 
with the extract appeared to prove its utility. 
Monsieur Simon Legrand, of Bersee, par Pont a Marcq, Nord, 
France, who is a seed grower of repute, exhibited samples of
