These tables, which have been carefully prepared for us by Mr. Amos, 
contain many interesting points. The small amount of variation in the 
draught of the several ploughs shows how nearly perfection has been attained 
in their construction. The last column, which may be said to sum up all 
the rest, deserves special attention, as enabling us to make the most complete 
and exact comparison of the actual draught of the different implements when 
removing a given quantity of earth. The unit of power spoken of is the 
power required to lift 1 lb. one foot high. 
Swing Ploughs. — In this division we proceeded in a precisely similar manner, 
working the implements at two depths, and carefully examining every point. 
We selected three for the Dynamometer test, the result was as follows : —

Note. — Ransoine and Situs's first run was lost by the plough being stopped by a large stone- 
We would here remark that too much stress must not be laid upon the 
Dynamometer tests of the swing ploughs, as owing to the hardness of the 
ground, and the absence of wheels to steady the implements, the draught was 
very unequal, and even with wheels great difficulty was experienced in obtain- 
ing an equal draught throughout. Indeed, we very much doubt whether it is 
possible, with horse-power, to obtain in hard or stony land an absolutely correct 
result from the Dynamometer. A little difference in the holding of the 
plough, or the height of the horses acting on the hold the driving-wheel of the
