314 Report on the Exhibition and Trial of Implements 



he known that three of these steam-engines were liable to burst 

 at any moment? It is hardly necessary to say that the Stewards, 

 on being informed, by one of the Judges, of this serious fact, 

 immediately ordered their fires to be extinguished ; and the 

 police had strict injunctions to remove any man from the 

 show-yard who should attempt to get steam up in a dangerous 

 engine. 



By desire of the Judges the Stewards ordered the exhi- 

 bitors of eleven other engines to limit their pressure to 45 lbs. per 

 square inch ; which caution would not have been required had 

 they been entirely free from danger. 



The safety of the public, and more especially the safety of the 

 unfortunate purchasers of these worthless steam-engines, demands 

 that a rule shall be made and strictly enforced to the effect that 

 " no manufacturer can be allowed to get steam up in his engine 

 in the Society's yard until the boiler has been previously ex- 

 amined by the Judges or the Society's engineers, and a certificate 

 of fitness obtained." 



The trials of Threshing-machines were undertaken by Messrs. 

 John Clarke, George Shackle, and Thomas H. Barker, on 

 Thursday, the 15th of July, and terminated on the evening of 

 Wednesday, the 21st. 



To facilitate their very arduous task, a tabulated statement of 

 performances, drawn up by Mr. J. A. Clarke, was adopted by 

 the Judges. The dynamometer was under the control of Mr. 

 Appold and Mr. Amos, jun. 



The Judges' Report on these important trials will be found so 

 ample in its details, and so admirably arranged, as to require no 

 remark in this place. 



Possibly many readers of these Reports may have stood within 

 two yards of a threshing-machine working its hardest for an hour 

 or two ; but if any reader will kindly continue this experiment 

 for twelve or fourteen hours on six consecutive days, he will then 

 be able to form a tolerable idea of the labours undergone by the 

 Judges of threshing-machines at the Chester Meeting. 



The Stewards regret extremely that these gentlemen were so 

 overworked, and are greatly obliged to them for having gallantly 

 carried through the duty they undertook with so much assiduity 

 and good humour. 



The merits of the Chaff-cutters, Root-cutters, Root-pulpers, 

 Linseed-crushers, Oilcake-breakers, Winnowing-machines, Corn- 

 dressing machines^ and Cheese-making apparatus, were adjudi- 

 cated upon by Professor Wilson, Mr. Joseph Druce, and Mr. 

 John Hicken, whose Report bears testimony to the great care 

 and attention bestowed on these trials. 



Last, but not least, in this collection of excellent Reports
