the expenditure of considerable power. It is in fact beyond the 
power of two men to work it for more than a few minutes. 
The dynamometer trial (to be referred to at length hereafter) 
gave "24 as the horse-power required to work the fan open as 
•compared with '11 required by Phillips's hand fan working at 
the same speed ; and in the field, while one man worked Phillips's 
fan at the rate of 45-50 revolutions for fifteen minutes at a time, 
two men with difficulty worked the fan now under notice at 40 
revolutions per minute. 
The same exhibitors showed also a fan to be used as a 
"fixture, and worked by steam, water, or horse-power.

■ exhaust fan. Air pipes, air-chamber arrangement, thermometer, sliding 
valves, extra, if required, according to size of stackyard. This system is 
applicable to stacks in rows. The fan to be worked bj^ steam or horse-power,

This fan is a simple one of 15 inches diameter, with four rect- 
angular blades 7^ inches wide, running eccentrically in a sheet- 
iron casing, 21 inches diameter, with a 3-inch pulley on the out- 
side. The air inlet, which is on one side only, is 8 inches 
square. When worked, the frame was bolted on wood let into 
the ground. It seemed to the Judges to be of too flimsy con- 
struction to bear much work. The dynamometer trial gave 
1'56 as the horse-power required to give 1500 revolutions of the 
fan ; as compared with Phillips's power machine, which took 
1*77 horse-power for 2052 revolutions, and Lister's, which took 
1"75 horse-power for 1000 revolutions ; while the water-gauge 
test showed a displacement 2*45 in. against Phillips's 2-85. 
The exhibitors state that they have " simply studied to 
obtain the utmost simplicity with efficiency, discarding all 
gearing."

The fan in this case is an unenclosed turbine wheel, 14 inches 
in diameter, and 4] ^ inches in width, made in one piece, and 
driven by a strap from a wheel 54 inches in diameter on to a 
pulley of about 3 inches. The air inlet on one side of the drum 
is 1\ inches in diameter. The flue used is a wooden box, 
5f inches square, with a cast-iron cap for fitting on to the 
machine. The fan and driving-wheel are on a light skeleton
