Althougli inello:ible for the prize, and therefore not brought to 

 trial, we must notice C. Burrell's Portable Mill for grinding 

 coprolites, as an implement much valued by large occupiers in 

 the Eastern Counties, who employ coprolites largely as the base 

 of their turnip manure, and who still consider they can make a 

 good article at a lower figure than that at which it is sold. The 

 4 ft. 6 in. French stones, built on edge, produced a capital sample. 

 Price, 130/. 



Iie][>ort on the Hand-power MacJdnes. 



It will not be necessary to attempt an elaborate detail of the trial of hand- 

 power machines. There was little novelty to describe, and provided the 

 implements were strong and simple in construction, the dynamometer affords 

 evidence of peculiar importance in guiding us to our decisions. 



Corn-Dkessing Machines. 



We felt no difficulty in awarding these prizes ; the two winning machines 

 producing with great ecomouy of time and less power samples very superior 

 to all the others. The division of corn in Tasker's machine was exceedingly 

 good, giving an excellent sample with only a modicum of good grain in 

 all the collected offals. The merits of Corbett's dresser was scarcely inferior : 

 whilst in several of more costly and complex structure the quantity of good 

 grain in the spouting was sadly in excess of what should be found there. 

 Each machine had a preliminary trial, and re-adjustment was made when 

 required. Two bushels of wheat Avcre allowed for each experiment. 



The following tables of dynamomical results cannot fail to be interesting, 

 and we tender our cordial thanks to Mr. Knight, our attendant engineer, lor 

 his valuable services. If, on examination, these tabulated I'orras be found, 

 seeminglj', not to agree throughout with the awards, it should be noted that 

 speed and lightness of draught would not in themselves assign the first posi- 

 tion, if defect in strength, and want of simplicity in the construction of the 

 working and wearing parts, or inferiority of sample produced, counteracted 

 those admitted advantages. 



Quantity, 2 bushels Wheat.
