330 Report on the ExJiihition and Trial of Implements 



For although the exhibitors were rather less in number, the implements 

 were more in number, of a higher class, and of greater value. 



The Reports of the Judges in the several departments, being so well par- 

 ticularized, leave but little to be described, and that very generally. 



Referring to the Awards of Prizes, it will be seen that Messrs. Hornsby 

 and Son took the first, for their portable steam-engine, and some improve- 

 ments in the details of their engine placed Messrs. Barrett, Exall, and Andrews 

 for the second prize. The table in the Report of the Judges will show that 

 the engines oF Messrs. Clayton and Shuttleworth, Garrett, Ransome and Co., 

 Tuxford, and Eaton, will not be extravagant in their consumption of fuel ; for, 

 taking the average price of coal at I85. per ton, the prize engine of Hornsby 

 and Co. will cost' 25. Qd., and that of Eaton 4s. 9c/., for the fuel required for 

 10 hours' working and getting up the steam in the morning; the engines of 

 the other makers just mentioned will range between the two sums of 2s. 6d. 

 and 4s. 9d. for working the same lime. 



Some of the engines of other makers were much behind in point of economy, 

 and one exhibitor was much disappointed when told that his engine burnt 

 twenty-one times as much fuel as the prize engine. 



With respect to the fixed steam-engines, the Society may congratulate itself 

 upon the very successful result in the first attempt +0 introduce this implement 

 into the show-yard and to the notice of agriculturists; the exhibitors brought 

 several very effective engines of this class, and it is to be regretted that, in 

 common with all first attempts, more satisfactory results could not be obtained 

 in the experiments. Still enough was ascertained to enable the Judges to 

 decide upon the merits of the implements, and at the next Meeting, if the 

 Society determines upon having a suitable boiler for testing these engines, 

 some good results will be obtained, as it is certain that exhibitors will bring 

 better engines now they have had their attention directed to the matter. 



The thrashing-machines exhibited were very numerous, and several of them 

 displayed many judicious improvements. Those adapted for working by 

 horse- power were worked by a steam-engine and having the horse-works 

 attached. 



As the power which they professed to require was accurately measured out 

 to them, the work done will represent truly that which can be performed by 

 the horses they require respectively. 



Although it may be contended that driving these machines by the drum- 

 spindle, and turning the horse-works through the agency of the barn-works, is 

 not the best way of conductincr the experiments, still it must be allowed to be 

 preferable to working them by horses ; and the additional business to be done 

 occupied so much time, that the testing-machine used at Exeter could not be 

 used at this Meeting; on the whole the experiments were very satisfactory. 



In the tables of the Report of the Judges the time the machine required to 

 do the work is given ; and if the time so given is multiplied by the number 

 of horses-power given to work the machine, the product will be a comparative 

 number that will represent the quality of each machine, so far as power is con- 

 cerned, in an inverse ratio to the magnitude of that number. 



Thus in Class No. 1 (see Tables), 



Garrett's machine of 2 horses power thrashed 60 sheaves in 7*1 minutes, and 

 Cambridge's ditto ditto in T3-5 minutes. 



Minutes. Horses. 



Then 7-1 X 2 = 14-2 horses, ref;uired to thrash 60 sheaves in one minute. 

 And 13-5 X 2 = 27 horses, required to thrash 60 sheaves in one minute. 



Hence one machine took but little more than half the power to work it that 

 the other required.
