Report of the Judges on the 
by their engineering brethren, and that such well-founded obser- 
vations as are made in them are weighed and acted upon. 
The first of these suggestions is, as to whether some ready 
means should not be devised for enabling the feed-heater to be 
cleaned out ; if this were done, the feed-heater would not only 
do good duty in heating the feed-water when all was new and 
in good order, but would continue to do such duty, and would 
act as a valuable . trap to receive a portion of the lime, which 
otherwise would be deposited in the boiler. 
The second of these suggestions is, that to obtain really sen- 
sitive governing of the engine, the governors, instead of being 
driven only at the engine speed, or even below the engine speed, 
as they were in many instances at this show, should be driven 
at a higher velocity, so as to open rapidly on a small increase 
in speed, and should be provided with springs to quicken the 
action of gravity, in returning them on a diminution of the velo- 
city of the engines ; and further, that for real uniformity of work, 
the arms should never be pivoted on pins placed between the 
spindle and the ball (as in Fig. 11), as such a position for 
Fig. 11. 
the pivot tends to most materially diminish the vertical height 
AB as the balls fly out; because whilst the ball rises from B to 
B', and thus diminishes that height, the produced line of the 
centres of the arm falls from A to A', and causes a still further 
diminution. 
To promote uniformity, the pivots should be on the side of the 
spindle awav from the balls, as in Fig. 12 (the spindle being 
slotted to allow of the passage of the arms), as by that arrange- 
ment the point of intersection of the arms of the governor-ball 
with the spindle rises as the balls rise, and thus the height A' B 
is kept much more nearly ecpal to the height AB.
