418 Report on the Newcastle Show-yard. 
Class I. — Light Land Ploughs. 
Wheel Ploughs. — In this division, as before stated, ten ploughs were 
selected for trial. After seeing these at work for some ^time, and carefully 
examining both the implements and their work, while in progress and at its 
completion, we selected four to be further tested by the Dynamometer. 
In carrying out these interesting experiments we had the assistance of one 
of Mr. Amos's aide-de-camps, Mr. Gcoghegan, to whom our thanks are due for 
the care and patience he displayed in overcoming difficulties caused partly by 
the hard state of the ground, and partly by the crushing and crowding of 
spectators. The following table gives these results : —

Note. — The unit of power is the force required to lift 1 lb. 1 foot high. 
Sluing Ploughs. — Of the five ploughs selected, only four started. Of these, 
that of Messrs. Kansomc and Sims, marked 1779 in the catalogue, and 
costing 31. 17s. Gd., made such decidedly superior work that we considered 
any further test unnecessary. 
We award as follows : —

Class II. — General Purpose Ploughs. 
Wheel Ploughs. — We tried ten ploughs in each division of this class, which, 
as might be anticipated, was most attractive to the numerous spectators. It 
is manifest that an implement capable of economical work in soils, light and 
heavy, and equally available for shallow or deep work, will be more sought 
for than such as are suitable to particular cases only. We tried these ploughs 
at two depths, first at 5 inches, and afterwards at 7 inches, and such was the 
condition of the soih, that it was quite sufficient work for two powerful horses 
to draw the implements at the latter depth. We selected six ploughs for 
further testing ; the result is contained in the following table : —
