mills. The American mill consists of a fluted barrel cone- 

 shaped, the surface of the best chilled metal, revolving^ in contact 

 with similarly fluted breasts ; the corn enters at the upper end 

 of the mill, and is passed round and round until it is delivered 

 as fine or coarse meal, or only kibbled, according to the 

 proximity of the breasts to the grinding surface. The rapidity 

 with which ordinary work can be performed, the moderate power 

 consumed, and the comparatively low price, are points in favour 

 of these machines. 



Messrs. Turner and Fardon's mill is probably more ingenious 

 than practical ; a spiral screw runs from end to end above the 

 barrel, revolving independently ; this screw passes the corn 

 forward after being carried round by the barrel, and the rapidity 

 with which it is driven determines the coarseness or fineness of 

 the sample. The power was too great, and the corn handled 

 quite warm. The judges mention 8 machines as entering for 

 trial, yet the results are only given in 2 cases, a matter of regret, 

 as exhibitors are generally anxious to learn all they can as to the 

 draft of their machines. 



The novelty in the mill class is the patent crusher exhibited 

 by Stather and Thompson of Hull, which has been used largely, 

 and Avith great success, to crush cotton seed, grind locust beans, 

 and palm kernels. The peculiarity consists in the fact that the 

 work is done without contact. The iron beaters, which resemble 

 the arms of a whitecoater in a thrashing machine, are not within 

 an inch of the ribbed concave, against which the corn is thrown 

 and broken by centrifugal force, caused by the beaters revolving 

 some 3000 times per minute. This mill is simplicity itself, 

 consisting of a narrow cylindrical box, into which the corn is 

 admitted above and escapes through the meshes of the wire slides 

 which form the sides, and are altered according to the nature of 

 the artic]j3 and the fineness of sample required. It is quite 

 evident from the trials we Avitnessed that any hard dry substance 

 must be reduced, but we apprehend difliculty with soft damp 

 corn, and it will be noticed that the barley was not well ground, 

 while other harder substances were thoroughly reduced. Bones 

 were speedily made into powder, and samples of coprolites were 

 shown, although we did not see them ground. We understand from 

 the judges that the power consumed for a given quantity did not 

 greatly exceed that of the prize metal mill, but a much longer 

 time is required. This is an objection, and we are led to con- 

 clude that this highly ingenious machine is not in its present 

 form so Avell adapted for a farmer's use as cither an American 

 metal mill, or a good pair of Burr stones. The fittings were 

 evidently rude, and might be considerably improved. We regret 

 that the judges have not given the power consumed in these 

 trials, and entered more generally into details.
