any further use of air currents in the ordinary way is of little value ; hence the operations 

 must be largely confined to sieving. Here is where the New South Wales methods seem 

 to me to be capable of much improvement. We are, in my opinion, too slow in adopting 

 on our farms sifting machinery of the best type, and even fail to appreciate that which 

 we already have available. 



Grading Machinery. 



I recently had an opportunity to examine machinery of this class ^in operation, in all 

 the leading grain-growing countries of the Northern Hemisphere, as well as an extended 

 opportunity to examine the collection of competitive exhibits of this class at the Paris 

 Exposition, an exhibit that was most completely representative of all the European 

 countries, notably those of Middle Europe, where these machines have reached a high 

 degree of perfection. As the result of thoroughgoing observation and trial that must

 dust and chaff is blown; 5, 6, spouts 

 connected with 3 : 7, 8, 9, 10, spouts 

 from which various grades of grain are 

 delivered. A revolving bristle brtish 

 is shown acting on the cylindrical 

 screen, which, as in the case of Fig. 33, 

 is in three parts, each easily replace- 

 able by a screen of any desired mesh. 

 The screens are sheets of perforated 

 metal, which lie flat when not in use 

 on the machine, and hence take up 

 very little room. 



have covered between forty and fifty different makes of grading machines, the impression 

 left was a strong one that the machinery of this class in use in this State is very much 

 below the best modern type, whether we take for comparison the machinery to be found 

 on our wheat farms or that found in our flour mills, though in this latter respect the 

 comparison is much more in our favour than in the former, from the fact that many of 

 our mills are very well equipped.
