approximately 1,460,000 bushels, equivalent to 40,000 tons, for which 

 freight "has to be paid.

 Previous Tests Compared with this Season Test. 



It is to be regretted that the percentage found in the wheat from 

 South Australia and Victoria for this season shows a marked increase 

 above the amounts found in the previous test. 



Grading Test. 

 After the usual preliminary cleaning of the sample to remove the 

 foreign matter, the wheats were graded by means of a set of hand 

 sieves of varying mesh, ranging in size from 3.25 mm. to 2 mm. mesh. 

 By this means it was possible to separate the grains into seven different 

 sizes, with the following result: —

(1,000 grams taken). 



Plate I. 



It will be seen on referring to Plate I. that the curves representing 

 the wheats from New South Wales, South Australia, and Victoria agree 

 fairly closely, South Australia showing a lesser amount of large grains 

 compared with the wheats of New South Wales and Victoria. The 

 curve representing the Western Australian wheat is quite distinct, 

 showing a high percentage of small grain. Unseasonable weather dur- 

 ing the ripening stage of the wheat may have affected the crops, and in 

 all probability accounts for the poorer development of the grain. The 

 amount of screening, whicli represents the cracked and shrivelled grain 

 not retained on the 2 mm. mesh sieve, has been reduced when the 

 general average is compared from 4.4 per cent, in the wheats grown 

 during the season 1913-14 to 3.2 per cent, for the wheat grown during
