 adopted by Messrs. Walker & Sons and also by Messrs. 

 Kell & Co. on their " John Bull " seems hard to beat, and 

 undoubtedly greatly increased the effectiveness of their pres-

The Judges were unable to recognise any particular 

 advantage in the American disc type of coulter exhibited by 

 Messrs. Thomas Baker & Sons on the conditions under which 

 these trials were held, though no doubt they may have their 

 merits under certain conditions. 



It was next arranged to test the " adaptability " of the 

 drills, and with this object the competitors were asked to alter 

 their di-ills and sow seven rows of beans. 



Three and a half stones of beans were placed in each 

 machine, and instructions were given to sow the beans at the 

 rate of one sack per acre, over a " run " of 2,50 yards.
