Trials of Implements at Carlisle. 
.ibles remain, as is almost universally the case, at the old- 
fashioned 60 lbs. ? 
Messrs. Armstrong^ Addison, and Co., Sunderland, showed 
Gates, Fencing;, and Wood-paving pickled by their process, by 
means of which great durability is ensured. They state that 
sleepers so treated have been in use on the North-Eastern 
Railway for twenty-seven years ; and that wood-pavement on 
the Sunderland Bridge is still good, although for thirteen years 
it has been subjected to heavy traffic. 
Messrs. Richardson and Son, Carlisle, showed a Potato-sorting 
^Machine, which efficiently makes three clean separations, large, 
seconds, and small, the dirt falling by itself. It consists of a 
series of screens of galvanised wire, and is an adaptation of the 
principle of the winnowing machine, being worked in a similar 
manner by hand. Several minor details of construction appeared 
capable of improvement, which will no doubt be done in future, 
the machine in the Yard being the first of its sort. 
Messrs. Perkins, Paternoster, and Burlinf/ham, of Hitchin, 
had a collection of Polygon Corn-screens of various sizes, suit- 
able to both farmers and seed-growers, which, by varying the 
barrels, can be made to separate any different sorts of seed. 
No. 712 in the Catalogue is stated as being capable of screening 
from 40 to 60 quarters of corn per day by hand-power, 
Messrs. J. and F. Howard, of Bedford, exhibited a new 
Plough, steel being used instead of wrought iron. The beam is 
bent round in one piece, and carries the share and mouldboard, 
thus doing away with the casting that has hitherto been used, 
and making the plough stronger and lighter. 
They also showed a new class of Haymaking Machine, the 
travelling wheels of which are mounted on axles, with an 
eccentric movement, so that bv a partial revolution of the axle 
the gearing is thrown in or out, the large tooth-wheel on the 
axle has " open teeth," so that if any grass or dirt gets on it 
they are punched through by the teeth of the pinion. The fork- 
head springs, which are important points in a haymaker, are 
simply straight strips of riband steel, which are just the right 
length when the forks are in either position to retain them there 
without being in a state of compression. They thus seem 
effectually- to fulfil all the required conditions, and can be 
replaced without anv tools. 
A Steam Cultivator, with a harrow slung to it from a pair of 
bell-crank levers, the other arms of which are connected with 
the turning lever, which lifts the harrow clear of the ground at 
the moment of turning, is a very neat and novel arrangement, 
and was also exhibited by Messrs. Howard, amongst other steam- 
cultivating appliances.
