ELEVATOR SCREENINGS

The results given below were obtained from the analysis of 

 another series of samples representing the lower and feed grades of 

 wheat, oats and barley. These samples were also secured from the 

 Grain Inspector at Fort William. The analyses were made after the 

 separation of the smaller or so-called "black seeds" by means of the 

 one-fourteenth inch perforated zinc screen. The percentage of these 

 smaller seeds by weight occurring in each grade is also indicated in the 

 table. 



Weed Seeds per Pound in Lower Grades of Western Grain 



Dockage 



Most of the Western grain entering commerce is shipped eastward. 

 At Winnipeg it is graded/ and on its arrival at Fort William or Port 

 Arthur is taken into the terminal elevators and stored according to 

 grade. That is, grain of the same grade is binned together. It often 

 happens that a carload of grain contains too high a proportion of weed 

 seeds or other impurities to be binned with the grade to which its 

 quality entitles it. In such cases the grain is graded according to its 

 quality and a dockage set representing the percentage by weight of 

 impurities which must be removed by the cleaners before it is binned. 



The material removed in bringing the grain up to the standard 

 of cleanliness for the grade to which it has been assigned constitutes 

 the screenings. 



The total dockage set by the Inspection Department, Board of 

 Grain Commissioners, Department of Trade and Commerce, on the 

 wheat, oats, barley, and flax received by terminal elevators for the 

 year ending August 31st, for each of the past few years was as follows:
