G98 Report on the Trials of Implements at Beading. 
The power of the fans to reduce the heat of the stacks is 
evidenced bj. the difference between the morning and evening 
observations on days when work had been done, and also by 
the sudden rise which sometimes occurred after a day when the 
fans had been idle. The maximum temperature observed * in 
each of the stacks is marked by an asterisk (*) in the Tables, 
but it may be interesting to place the results side by side for 
the purpose of comparison :

It will be seen that four out of the six stacks developed their 
greatest heat within three to five days after the stacking ; while 
in the two stacks which heated most, the hottest time (so far as 
these observations extend) was thirteen days after the corn was 
put in the stack ; and it is perhaps worthy of notice that on 
this day Coultas's two stacks rose in temperature though the fan 
was working. There is no doubt that the excessive heat in 
Phillips's (B) and Lister's (B) stacks was due to the big thistles 
and the weeds, of which these exhibitors had a large share ; but 
making due allowance for this difference, it would still seem 
that Mr. Coultas had more command over the temperature of 
his stacks than either of the other competitors. 
On the 11th of September the Judges, having inspected the 
stacks, came to the conclusion that it was useless to carry on 
the experiment any farther. Though the fans had been at 
work for a month, there was evidently a good deal of latent 
heat ; and the fusty smell of the air which was discharged from 
the fans betrayed the condition of the interiors of the stacks. 
Orders were therefore given for the threshing of the corn, and 
Mr. Wiggins, the grower of the barley, who had undertaken the 
threshing and dressing, promptly made his arrangements, and 
threshing was begun on the morning of the 12th, Coultas's 
Stack A being first threshed. This stack had slipped away 
from the stacker, and one side was only kept up by means of a 
* It is quite possible that the heat of the hottest parts of some stacks was 
never gauged.
