more fortunate than the last-named, was not so well in as the 
first. 
As has been said, stacking was begun on the 10th, and on 
the 11th all the fans were at work on the stacks first made, the 
highest temperatures observed up to that time being as follows : 
Coultas (A), N. 70°. Phillips (A), S. 88°. Lister (A), K 82°. 
On the 12th (Saturday), the other stacks having been com- 
pleted, each exhibitor worked his fan upon both of his stacks. 
On the following day (Sunday), Lister only worked, and on 
Monday morning a considerable rise of temperature had to be 
recorded all round. The maximum and mean readings were as 
follows :

Some mischievous or ill-disposed person had in the night of 
Sunday let all the water out of the engine used by Mr. Phillips, 
and taken away some nuts and bolts, which it took some hours 
to replace, and before the fan could be got to work the tempera- 
ture in Stack A had run up to 123°. 
In the Tables on pp. 721-726 will be found a full record 
of the fan-workings, and the morning and evening readings 
of the thermometers. It is not necessary to repeat here 
what is there told in minute detail. It will suffice to state 
that, from the 11th of August until the 11th September, the 
fans were, except on Sundays, almost constantly at work during 
the day-time, as will be seen by the following Table : 
Aug. 11 to Sept. 11 (32 Days).
