Automatic regulators could also be constructed on the basis of a 

 cooling blast of air through the machine, or of the speed at which the 

 machine revolves, but the regulation of the steam pressure would 

 probably be found the most satisfactory. 



With the alterations outlined above, the machine should prove 

 thoroughly satisfactory. The initial cost in this country of the 

 machine itself, exclusive of the donkey engine and other accessories, 

 is between L.E. 200 and L.E. 250. In running the only requirement 

 is the necessary steam power. No extra labour is involved, the seed 

 being sacked as it comes from the machine instead of as it comes from 

 the gins in the usual way. The machine is therefore cheap as regards 

 both initial cost arid running expenses ; it is very compact, simple of 

 construction, easy of management, continuous in action, and entirely 

 devoid of danger ; it is therefore a practical proposition from every 

 point of view. During the last eighty-one minutes of the above 

 experiments it dealt with nineteen ardebs, its output thus being 

 fourteen ardebs per hour.
