Report on the Trials of Implements at Cardiff. -141 
form of shakers used by each maker was the same in Class II. as 
in Class III. To ascertain which form of shaker did the best 
work, we may therefore take the average results which the three 
or four trials with wheat afforded in the two classes.

The order of merit is evidently not independent of the methods 
of construction adopted, and may probably be taken as really 
indicating their relative advantages. 
The single central crank will, we believe, be less costlv to 
maintain than the double cranks, but may probably require more 
power to work it than is needed by the revolving bars.
