Report on the Trials of Implements at Reading. 677 
day the work was interrupted by heavy showers. The staddle 
was laid out 20 feet square ; and the flue was a galvanised- 
iron pipe, 8 inches in diameter, laid just in the ground. Over 
the inner end of this pipe a shaft was made by using a light 
circular cage 2 feet in diameter, constructed of wooden slats 
bolted on three iron hoops. The cage was 6 feet high, and 
as the stack rose it was pulled up until roofing began, when 
it was taken out and the shaft left without any support. In 
this respect Mr. Phillips's practice differed from that of all 
the other exhibitors. Tuesday the 11th, as most visitors to the 
Show-ground will remember, was a pouring wet day. On 
Wednesday the 12th the stack was finished, excepting a few loads 
which were afterwards put in the roof. The hay was a good 
defil weathered, and it was put together rather wet. In the after- 
noon of the 14th the temperature on the north side of this stack 
was 145°. The fan was worked from 3.30 to 4 p.m. by a 
Ransomes and Head's 1 J-horse-power vertical engine, at 2500 
revolutions of the fan per minute. The temperature at starting 
varied from 145° to 65°. After half-an-hour's work the higher 
temperature was brought to 134°, while on the windward side of 
the stack the heat remained at 65°. As this hay was undoubtedly 
wet, Mr. Phillips's representative, Mr. Giles, was not anxious to 
reduce the heat too much. For a week after the working the 
temperature of this stack remained at about 140° on the north 
side, and then the heat shifted to the east. On the 21st the fan 
was worked for 1 hour 25 minutes, and the heat was brought 
from 145°, 158° and 127°, to 125°, 125° and 123°. After this, 
the heat gradually declined, and no further application of the 
fan was thought necessary. Altogether this fan worked 1 hour 
55 minutes (see Table V., p. 705). 
This rick when cut up was mouldy almost throughout. In the 
middle there was a small quantity of brown hay. The stack was 
sold for 14/. 10*., there being about twelve tons of it. Taken 
altogether, it was inferior to Coultas's stack, but it was more 
weathered before stacking, and the nature of the grass was coarse. 
Plot IV.— C. D. Phillips. 
Fan worked by hand-power. This plot of about 5 acres, 
like the last, was a heavy crop of coarse hay. It was mown on 
the 4th, and stacked on the 12th and 13th in bad condition. 
The stack bottom was laid out for a circular stack 21 feet in 
diameter. The flue was a square wooden box, 7j inches by 
lOJ inches and 13 feet long ; it was laid with its upper 
iBurlace level with the ground. Over the inner end a shaft was 
blade, as in the exhibitor's other stack, with a light round cage, 
which was raised to the required height, and then removed. 
By the 19th the temperature was up to 154°, and on the 20th the
