678 Feport on the Trials of Implements at Reading. 
fan was worked for an hour by two men, who relieved each 
other at 15 minutes' intervals. The speed maintained was from 
45 to 50 turns of the handle per minute, this giving from 585 
to 650 revolutions of the fan. The effect of the fan was to 
reduce the heat from 150° to 104° N., from 112° to 100° S., and 
from 140° to 112° VV. On the 21st the fan was worked again for 
half an hour, as the temperature had risen again considerably 
on the N. and W., and at the close of the day the heat was 
greater at these points than on the evening before, viz. N. 111°, 
W. 115°. The stack was then left until the 25th, when one 
hour's work reduced the average from 120° to 97°. On the 
26th, the wind being N., the heat on the S. rose to 139°, the 
fan was worked for 35 minutes, and diminished this to 118°; on 
the 1st of August another hour's fanning was given, and the 
stack was then left to itself (see Table VI., p. 706). 
When cut open, this rick was very similar to No. 3. Almost 
the whole of the mass was mouldy. About 10 tons of this 
musty hay fetched only 13Z. 
Plots V. to VIII. 
It has been already intimated that Plots 5, 6, 7, and 8 were, in 
consequence of the weather, abandoned so far as regards trials. 
Having been continually tedded and shaken out, the hay had 
lost all its nature, and when a little fairer weather came, it dried 
so quickly that there was no chance of its giving any work to 
a fan or ventilator. 
Only one of these stacks, that on Plot 5, was put up to 
auction ; the others, being on the Corporation farm, were taken 
over by the manager on terms which had been previously 
arranged. It is worth notice that this hay, the produce of 
about 4 acres, estimated to weigh about 10 tons, sold for more 
money than either Champion's stack dried by Gibb's hay-dryer, 
or Coultas's fanned stack. It must be borne in mind that this 
hay had lain scattered about the land for a whole fortnight, until 
it was completely weathered and brown, and that it was only 
got together when extra hands and teams could be obtained. 
For reasons which have been already stated, the sale prices 
of the hay-stacks cannot be t.aken to represent the real value of 
the hay — and indeed, in the absence of any competition, it 
would be unsafe to rely upon thorn as evidence of the compara- 
tive value of the different stacks — but as some of the exhibitors 
have taken occasion to glorify themselves on account of the 
higher prices which their stacks made (without, however, taking 
into account the quantity of hay in those stacks), it may be 
worth while to point out that, in so far as the opinion of the 
public as to the merits of the artificially dried hay was shown, 
it appeared that they preferred to give a higher price per toa
