climatic pouditions during the growing period, might be noted. Tests 

 were made for : — 



Ist. Determination of the amount of impurities, and the [)roportion 

 of the various ingredients. 



2nd. (Irading the wheat into different sizes, and the proportion of 

 the various ingredients of each size. 



3rd. The busliel weights of original and cleaned weight. 



4th. The milling test. 



5th. The gluten content, the strength, and the colour of the tlour. 



6th. The baking test. 



The following table shows the amount of foreign matter found in 

 wheats from the different States : —

The impurities present in the largest quantity in all the samples arc 

 barley, chaff, and drake, the Victorian sample containing, in addition, 

 a fair amount of oats. Every effort should he made to remove these 

 impurities at this end, for not only would their absence increase the 

 milling quality of wheat, but, further, freight charges would be lessened. 

 Calculated on bulk samples examined, it is estimated that in a normal 

 year, 24,000 tons of these foreign bodies are sent overseas mingled with 

 our -(vheat, and while they are useless for milling purposes, they are 

 suitable food for cattle and horses, and could be used to advantage here. 



The statement hereunder shows the percentage of foreign matter 

 found in the wheats tested for the seasons 1912-13 to 1916-17: —
