GOG Report on Miscellaneous Implement Awards at Derby. 
sections can be piled up as so many blocks ready for use, or 
the bale can be placed on end, and gradually reduced by the 
removal of consecutive sections. Considering the rapidity of 
the work there is very little waste. 
The Judges weighed a truss 12" X 15" X 3G", which scaled 
1 cwt. 1 quarter 16 lbs., being about 42 lbs. to the cubic foot, 
whereas the exhibitors claim to, and probably could, com- 
press 45 lbs. per cubic foot, which would allow 1 ton of hay 
to be packed within 1 ton measurement of 40 cubic feet. In a 
time test it was found that 3 feet 8 inches of hay was dis- 
charged in two minutes. As this weighed 191 lbs., and the 
work is continuous, it follows that the machine can bale in 
round numbers about 2J tons per hour. Whereas the Filter 
Press, which makes a circular truss, and was awarded a Silver 
Medal at Kilburn, bales only 1 ton per hour, and costs 100/., 
the Perpetual Press is catalogued at 275Z. 
The Judges considered that this machine has merit and 
utility for the following reasons : — The rapidity of execution 
and the small cost of manual attendance ; the peculiar way in 
which the hay is passed in sections ; the simple action of the 
presser, minimising waste ; and the advantage of the rectangular 
form of truss for stowage as compared with cylindrical trusses. 
It has yet to be seen to what extent, if any, such a machine 
may be applied to comparatively green hay in the fields. The 
exhibitor claims that such compression would prevent fermenta- 
tion, even if the hay were packed in a much greener state than 
that in which it is ordinarily stacked, and this opinion was 
shared in by Mr. Scotson, one of the Judges, who is an exten- 
sive hay-seller, and who held a strong opinion that through its 
agency hay might be secured from the field in a greener, and 
therefore more valuable condition for many purposes than when 
stacked and sweated according to ordinary practice. The fact 
of the hay being so closely packed would, by excluding the air, 
prevent heating ; moreover, the bales could be so stacked in 
barns or sheds as to secure ventilation between them. One 
machine, capable of pressing 2^ tons per hour, could deal 
with the crop as rapidly as by ordinary stacking. The hands 
employed would be less numerous, and when the market is the 
destination, such a scheme seems very practicable. The wire 
rope or bands can be used over again until worn out.

simplicity and efficiency of this guard commends itself. The 
figures which give the elevation and end view require (Fig. 5 
and G) but little explanation.
