slowly and almost imperceptibly upwards, and to carry the 
contents of the box with it. As the manure is brought in 
contact with the spikes of the rake it is tumbled over the edge, 
and falls in a continuous stream to the ground. The rake and 
the box are worked in unison, and by altering the gearing the 
speed at which both are moved may be changed, so that any 
quantity between 70 lb. and 10 cwt. of a substance such as 
nitrate of soda may be applied per acre. The speed is determined 
by the pace of the horse, and as the substance does not change 
its density or consistency the distribution is necessarily uniform, 
and is practically perfect. The weight of the material does not 
affect the evenness of the distribution, and the machine will sow 
grass seeds, grain, superphosphate of lime, or nitrate of soda 
equally well. The parts are few, and there is little likelihood of 
the machine getting out of order. The price of the machine, 
to distribute 7 ft. wide, is 201.

The special feature in this case (Art. 1239) is an arrangement 
of thin conical discs (fig. 2) which, when placed inside the

of the machine. The discs are fitted to the various forms of the 
Laval Separator, and are attached to the spindle of the drum.

They are made of steel, and, except that the base is cut out to 
allow the spindle to pass through them, they resemble the 
common pattj'-pan in shape. A number of discs are threaded 
on the spindle, but, by means of grooves in each disc, they are 
prevented from coming closely together, a space of one-sixteenth 
of an inch being left between each pair. The spindle is passed 
through the bowl, and is secured by means of a screw. The
