xvi Report of Implements shown at Cambridge. 



Of Turnip-Cutters there was not much variety ; public attention 

 being now apparently confined^ in these machines^ to two rival 

 principles^ — viz., that involved in Gardner's patent cutter^ in 

 which the movement is cylindrical ; and that of Hart's, in which 

 the cutting' part is attached to a cast-iron plate, and the move- 

 ment vertical. It would be well if, on some future occasion, the 

 respective merits of these exceedingly valuable implements were 

 fairly brought to the test. 



Of Iron Rollers there were several : the judges distinguished 

 one, made by Mr. Wood, of Stowmarket, intended for rolling 

 barley or other spring corn, in which there appeared novelty. 

 The roller was in two parts ; the one part placed a little in ad- 

 vance of the other, so that in turning the movement of each part 

 is reversed, and thereby an actual saving of power is obtained, 

 and a considerable evil obviated incident to rollers in general, 

 which in turning are apt forcibly to displace the soil and disturb 

 the new-sown seed. A Clod-Crushing Roller, made by Mr. Cros- 

 kill, of Beverley, was also exhibited, which in particular cases 

 has been proved to be a most valuable implement ; land the most 

 tough and stubborn, and clots of earth the most unmalleable, 

 being by it reduced to powder. That considerable notice has 

 been attracted to this implement is evident from various causes, 

 especially from the fact of another being exhibited on this occa- 

 sion professing to work on the same principle, but in reality being 

 divested of the essential quality of Mr. Crbsskill's; his clod- 

 crusher consisting of a series of cast-iron rings having a dentated 

 surface, and hung rather loosely upon an iron axle ; and thus in 

 working (and it can only work on a dry soil) an irregular shaking 

 movement occurs, preventing thereby the possibility of any clog- 

 ging; a fault into which that of the imitator seemed liable to 

 fall. Mr. Croskill showed also a Liquid- Manure Cart, which 

 was thought to merit the Society's reward. 



There were Cake-Crushers of various descriptions ; one, of the 

 manufactory of Messrs. Bond, Turner, and Co., of Ipswich, was 

 very much noticed : it was made for the purpose of crushing 

 cake, by one movement, for beasts, sheep, and tillage ; and this
