The same ploughs were then put to work at a depth not less than 

 7 inches, when we found the following did the work best in the order in 

 which they are placed : — 



No. 1. Busby's. 



No. 2. Howard's, marked XX. 



No. 3. Howard's, marked XXX. 



Ball's plough, which at 5 inches appeared No. 1, broke the land too 

 much at the extra depth, owing to the formation of the mould-board 

 pressing too heavily on the furrow. The work done by the whole of the 

 swing-ploughs was moderate, especially that by the Scotch ploughs, which 

 was decidedly bad. The three best ploughs, viz., Mr. Busby's, Mr. 

 Howard's, and Mr. Ball's, were then taken to the heavy land, and were 

 subjected to a very severe test. The work there was satisfactorily com- 

 pleted, and we place the ploughs according to the following order of 

 merit : — 



No. 1. Busby's. 

 No. 2. Howard's. 

 No. 3. Ball's. 



Mr. Howard had-one plough only tried on the stiff land. The ploughs 

 were tested as before — first, at not less than 5 inches deep, and then at 

 not less than 7 inches, and the same result appeared at both depths. 

 The objection observed in the plough of Mr. Howard was, that there ap- 

 peared to be too much curvature in the tail of the mould-board, which 

 caused the land to break up in turning, and a great advantage was thus 

 given to the plough of Mr. Busby: at the same time, Ihe work done by 

 Mr. Howard's plough was very good ; that of Mr. Ball's good ; but that of 

 Mr. Busby's was superior. 



Three 4-horse ploughs were tried in the lighter land at a depth of from 

 9 to 10 inches ; they appeared on that in the following order of merit ; — 



No. 1. Busby's; No. 2. Hensman's ; No. 3, Howard's. 



Six Subsoil Ploughs exhibited : — 



No. 1. Bentall's ; 2. Grey & Son's ; 3. Comins' ; 4. Coleman's. 



In the latter an improved system of adjusting the lever appeared, the con- 

 struction of which we consider to be good. 



In the turn-wrist ploughs we considered that none were exhibited 

 deserving of remark. Lowcock's one-way plough could not be worked, 

 owing to a portion having been lost on the railroad ; but having tested 

 it on former occasions, we recommend it as worthy of notice. 



The best of the six Belgian Ploughs exhibited was that of Mr. Odeurs, 

 which cut the side clean and left the sole level. Worked steadily, and 

 was easy to hold. In the turn-wrist ploughs of Mr. Vaumael, a new 

 principle of turning at the ends of the land, and of the adjustment of 

 the mould-board, is worthy of consideration. The turn-wrist plough of 

 Mr. Dufour also worked satisfactorily. It is right to observe that Mr. 

 Busby had applied to his plough the moveable nose-piece invented by 

 Messrs. Ransome. Upon the whole, it is considered by the Judges that 

 the working of the ploughs was satisfactory.

It should be remarked that ploughs suited for common and for 

 deep ploughing distinctly have for some time been separately 

 encouraged by the Royal Agricultural Society. There can be no
