Report on the Trials of Implements at Reading. G85 
heat at starting was 122° E. and 117° W. At the conclusion 
these temperatures were reduced to 120° and 102° ; but a 
further diminution went on during the night, and at 9.15 A.M. 
on the 28th, the thermometers marked 110° E. and 100° W. 
The fan was going for twenty minutes in the middle of the day, 
and in the evening the temperature was 110° E. and 110° W. 
By the 9th of August, however, the temperature was reported 
as 130°, and the fan was again worked for half an hour. 
The stack was a circular one, 20 feet in diameter at the base. 
The flue was a tube of half-round sheet-iron, laid on the ground, 
and the shaft was an iron tree-guard about 8 feet high. 
The fan proved decidedly hard work for two men, and a third 
had to assist. There was really not the slightest necessity for 
any fan-working, and no thermometers were required to tell a 
farmer that it might be left alone (see Table XI., p. 713). 
When the stack was cut, the hay proved to be rather dry and 
scentless, and in the Judges' opinion it would have been better 
if it had never been interfered with. The estimated weight of 
this stack was about 9 tons, and it sold for 24/. 3s., an improve- 
ment in the prices which the hay of the first trials had made ; but 
the grass of this plot and the two next — Phillips's and Bamlett's 
— was far better in quality than that of the other meadows. 
. Plot XV. — C. D. Phillips. 4th Stack. Steam-power. 
Part of the hay which was stacked for this fan came from the 
same field as that which made up the one last described, and it 
had been subjected to exactly the same treatment. The re- 
mainder came from an adjoining field, where the grass was of 
similar quality. This grass was cut on the 19th, and turned, 
wind-rowed, and cocked in the afternoon of the 20th, but a part 
of the field was much shaded by trees, and the hay did not 
make so quickly as in Plot 14. On the 21st the cocks 
were shaken out, and a portion of it was stacked. Some 
rain fell in the night of the 21st and the morning of the 22nd, 
and the hay was not thoroughly dry when stacked. The ex- 
hibitor made exactly the same preparations for this stack as 
for his first. On the 24th the heat had reached 143° N., 
148° E., while it was only 64° S. The fan was worked for one 
hour, the same 1 J-horse-power engine being employed as at 
the other stack, and the temperature at the close of the working 
at these points was 132^ N., 113^ E., and 62° S., the average 
reduction being 15°. Again, on the 26th, one hour's work was 
given, with the result that an average decline of 17^° occurred. 
By the 28th, 140° was again observed, and the fan was worked 
for 40 minutes, reducing the heat about 13° (average) ; but it 
will be seen on reference to Table XII., p. 714, that by 4 P.M.
