Report on the Exhibition of Implements, 
the frame is a transversed crank-axle, e, to which is fitted a pair of travelling 
wheels, f. At the rear of the fiame are claws or tines for entering into the 
ground. The travelling M'heels when in use hold these tines out of the 
ground, their cranked shaft being locked by a pawl on the framing, a, en- 
gaging in a ratchet-wheel, h, keyed on the crank-shaft. When the crank-shaft 
is unlocked, the tension put on the hauling-rope will draw the tines into 
the ground, the attendant can then lift the wheels out of the way, and secure 
them in the position shown at Fig. 44 (p. 749). The roller, b, prevents the 
front part of the frame from dipping into the ground and thus tending to lift 
the tines. By a modification of the arrangement the roller is done away with, 
a hinged frame being used to carry the guide pulley, and the tines are fitted 
to the crank-shaft instead of to the framing, and are thus raised or lowered 
by the direct action of the crank-shaft. 
Of course without a proper trial it is rash to pronounce 
a strong opinion ; but these inventions appear decidedly meri- 
torious, and are therefore worthy of the short notice which has 
been given. 
Messrs. Hornshy and Sons introduced at Kilburn a novelty in 
their patent manure distributor. Although the Judges re- 
frained from expressing an opinion, inasmuch as they had not 
any opportunity for a thorough and prolonged trial, which is 
absolutely necessary in order to prove efficiency, there are some 
features in this machine that merit notice. 
The barrel, which rotates, has spiral projections throughout its whole 
length ; each of these projections is acted on by a scraper, which removes the 
manure. As they carry it from the box or hopper each scraper works inde- 
pendently, so as to be easily adjusted. The barrel is fixed on the main axle, 
and therefore revolves in the same direction as the road wheels, and is di'iven 
by a spring clutch to throw it in and out of gear. Owing to this peculiar 
arrangement the attendant can ride in front, a pivotted seat being provided 
for this purpose, and can see and control the action of the drill, instead of 
having to walk behind as formerly. A .-et of stirrers in the hopper, moving at 
a slow speed to and fro upon a plate, are intended to prevent the manure 
sticking ; they are driven by a revolving cam on the main axle, and the plate 
and stirrers can be readily removed for cleaning. The manure as it falls from 
the barrel, drops upon a rotating distributor, with a view to its even distribu- 
tion over the land. The advantages claimed are, that the slow speed of the 
barrel and stirrers, and the openness of the box, prevent the manure being so 
much worked up into a paste as is commonly the case. 
The last novelty which I shall notice is Pooley's Patent 
Automatic Weighbridge, which, though specially adapted for 
railway purposes, might be equally applied for agricultural uses. 
The object claimed to be attained by this invention is the rendering of 
lever weighing-machines automatic in their indications, without the inter- 
vention of springs, racks, sectors, or pinions. The weight is indicated by a 
finger rotated against a graduated di.sc, the finger being secured to a 
light spindle revolved by a very light and pliable chain. The principle is 
that of counterpoising the load, hy means of a weight taken up by the , 
extremity of the long arm of a lever, which weight increases or dimini.shes 
in effect, gradually, infinitcsimally, and automatically. The indexing finger 
driving-chain is attached to the long-arm of the lever; any change in its
