men generally, and should doubt its locomotive powers being of 

 much practical benefit as connected with agriculture, entertaining 

 a fear also that accidents might be of frequent occurrence in 

 steaming from farm to farm." 



" The duty performed for the coal consumed in this case was 

 below that of the prize-engines, as will be seen on reference to 

 the tabular statement. 



" This engine was stated to be better adapted to work with coke 

 than coal. 



" The other engines entered in the catalogue were not brought 

 into the trial-yard, with the exception of one by Mr. John Smith, 

 which was withdrawn by the owner without trial."

Threshing- Machines * — Great pains were taken with the trial 

 of these machines, as it was felt that their importance could 

 hardly be overrated, and yet that no trial of them had hitherto 

 been made which could be considered really satisfactory. A 

 great step in advance was undoubtedly made at York, where 

 for the first time the power required to work each machine 

 was ascertained ; but even this important step fell short of the 

 real requirements of the case, as the mode of registering the 

 power was by no means perfect, and the method then adopted 

 was also deficient, from its furnishing no means of judging of the 

 efficiency of the horse-works. A large majority of threshing- 

 machines are necessarily worked by horse-power, so that no state- 

 ment of their relative merits could be generally satisfactory which 



* The judges of threshing-machines requested the writer of the report to draw up 

 the account of the trial of these implements, and furnished him with the tables A, B, 

 C, &c, for that purpose.
