in every direction to avoid the creation of any eddies or back 
currents of air which are the result of any irregularity in the 
form of the air passage. 
Article 5234 — (jVew Implement.) — Fan ; manufactured by the Exhibitor. 
Price 10/. Phillips's improved exhausting and ventilating portable hand fan, 
mounted on a strong wood framework, fitted with multiplying wheels. It can 
be worked by one or two men, and is complete with travelling wheels and 
handle. {For Trial.) 
The entry, as printed above, does not correspond with that 
which appeared in the Catalogue, some mistake having occurred 
in the matter. The machine exhibited is described in the 
amended entry. The fan, 24 inches in diameter, has five blades 
of wrought iron, lOJ inches wide, and works in the centre of a 
sheet-iron case. It is driven by a cog-wheel and pinion, one 
revolution of the former giving ten of the latter and of the fan. 
The air inlet is 7J inches by 10 inches. It is continued to the 
ground, where it fits into a wooden box flue. The machine is 
mounted on a stout wooden frame fitted with two wheels and 
handles for moving it wheel-barrow fashion. At the dynamo- 
meter trials the power required to work the fan open at the 
rate of 60 turns of the handle per minute was 0"42-horse-power. 
In the field two men relieving one another at intervals of 15 
minutes kept up a speed of about 50 per minute.

YeSTILATIOX IX THE StACK. 
Stand No. 184.— C. Kite and Co., of 117, Chalton Street, Euston 
Eoad, London, N.W. 
Article 4000 — (Ae?y Implement.) — Hay and Corn Dryer ; manufactured 
by the Exhibitors. Price 41. per single set. For ricks and stack sheds. This 
consists of perforated drums or pipes with automatic exhaust ventilator fixed 
on top, and placed perpendicularly along the middle of rick, to form one or 
more cavities as may be required, according to the size of stack. Also models 
of the above. (For Trial.) 
The method proposed for adoption by the exhibitors is that 
of a central shaft, terminated by an automatic ventilator which 
rises above the roof of the stack. In connection with this shaft 
a pipe or pipes are laid horizontally at or near the bottom of 
the stack, and extending to the outside of it. A very slight 
indraught of air causes the ventilator to work, and thus to 
increase the velocity of the passage of air through the stack. If, 
however, the dampness of the atmosphere is such that there is no 
movement of air, a draught is easily created by the introduction 
of heated air supplied by a slow combustion stove. Although 
the Judges looked upon this apparatus as being of the nature of 
a toy, they did not feel justified in refusing it a trial.
