22 Report on Miscellaneous Implements at Shrewsbury, 8fc. 
Newark-on- Trent, exhibited a powerful Bone Mill and Bone 
Duster. This mill has double steel segmental rollers, 16 in. 
wide, and two concaves with friction clutch. It was stated to be 
capable of reducing raw bones to f in. and ^ in. pieces, at the 
rate of 5 to 6 tons per hour, or to bone-dust and \ in. size at 
the rate of 3 tons per hour. The machine was worked in the 
presence of the Judges, and, during this short trial, did its work 
very effectively. A new Turnip Cutter was also on this Stand, 
price 4Z. 10s. The angle knives, to cut finger-pieces for 
sheep, are arranged in spirals on a hollow plate-wheel, in a 
form which is stated to ensure continuous cutting and the least 
possible resistance from the roots, which are cut up to the last 
piece without waste. 
The " Acme " Pulverizing Harrow, Clod Crusher, and Pul- 
verizer, exhibited by Messrs. Lankester and Co., is one of those 
implements, the merits of which can only be accurately known 
by trial. It is an American invention, and, as will be seen 
from the accompanying drawing, wholly unlike any British 
form of Harrow.

" Acme " Pulverizing JTarrow, Clod Crusher and Levdkr. — As will be seen 
by reference to the illustration, an adjustable inclined levelling-bar and clod- 
crusher is provided, which is permanently attached to the pole. It consists of 
a strong bar of angle-iron to which arc attached cast-steel crushing-spurs, the 
alternate ones being extended and curved in such a manner as to form the front 
coulters. These are not placed continuously on the bar, but at a little 
distance apart, which arrangement, while it in no way diminishes the efficacy 
as a crusher and leveller, tends to prevent clogging in damp sticky soil, and, 
furthermore, enables the driver to see what is being accomplished. Perhaps
