356 Report on the Exhibition and Trial of Implements 



disintegrated throughout, while the furrow exhibiting various 

 cracks and fissures will at the next operation be discovered to 

 be comparatively a series of clods. The position at which the 

 furrow should rest when turned over is suj^posed to be most 

 correct when lying at an angle of 45° with the perpendicular cut 

 of the land-side : at the same time it must be thrown aside suffi- 

 ciently far to form a roomy horse-walk. And a plough performing 

 these conditions most perfectly was found in the prize imple- 

 ment to work at the lightest draught. 



The soil at the place of trial was in a very favourable state 

 for ploughing, and for testing the merits of the selected ploughs. 

 It was a clover-field from which a crop of hay had been lately 

 removed ; and a considerable quantity of the rakings was left 

 behind, which exhibited the capacity of the ploughs for turning 

 growing tufts out of sight. The appointed depth was first 5 inches, 

 then 7. Among the number which had been sent out from the 

 implement-yard, the superiority of that class, with which Mr. 

 Howard's name has been so long connected, was soon evident, and 

 an interesting struggle took place here, and afterwards in the heavy- 

 land field, between four of these ploughs for general purposes, 

 Mr. Ransome's, Mr. Howard's, Mr. Busby's, and Mr. Bell's, 

 which resulted in favour of Mr. Busby's. The draught was re- 

 corded by Mr. Bentall's new dynamometer in a very satisfactory 

 manner, in the heavy-land clover-field, with a furrow 6 inches by 9 

 inches wide, and the results as summed up by Mr. Amos were —

The Heavy-land Ploughs. — These had an equally favourable 

 field for their trial. Five of the before-mentioned class of 

 ploughs alone competed, namely. Busby's, Ransome's, Howard's, 

 Ball's, and Williams's. The contest was closely maintained by 

 Ball and Busby, and was ultimately decided in favour of Mr. 

 Ball. 



The Tarn-wrest Ploughs exhibited no great merit. Mr. Low- 

 cock's performed the best work. Mr. Comins's was of a respect- 

 able kind, considering that the mould-board compressed formed 

 the land-side. Mr. Howard's Kentish turn-wrest reversed the 

 furrow perfectly flat. An American tum-wrest was also a com- 

 petitor ; and it was, in reversing the mould-board, simple and 

 ready. But it proved itself out of place in land at all adhesive ; 

 its short, abrupt mould-board jerking the furrow over in a very 

 amusing manner, leaving the work with a half ploughed and half 

 scarified appearance.
