heavy freight rates this is seldom possible west of Moose Jaw. (2) 

 By burning them; on account of the high oil content of the black seeds 

 (Lamb's quarters and mustards) they burn readily and have con- 

 siderable value as fuel. (3) By feeding to cattle and sheep in stock 

 yards where it is not intended to keep animals longer than a day or 

 two. (4) In a few places they have been fed to sheep kept in en- 

 closures over a period of six weeks or two months. 



All through the West chop-feed made from recleaned screenings 

 sells readily and usually gives excellent results. Buckwheat screen- 

 ings make an especially satisfactory hog feed. 



The screenings removed in further preparation of the wheat for 

 grinding are pulverized and mixed with the bran and shorts, as in 

 the East. 



Results of Feeding Experiments with Screenings 



During the winter of 1914-15 the Animal Husbandry Division 

 of the Central Experimental Farm, Ottawa, conducted experiments in 

 the feeding of elevator screenings and their commercial separations, 

 with milch cows, swine, and lambs. 



the material 



In securing material for the experiments, pains were taken to get 

 screenings representing as nearly as possible the average cleanings 

 taken from western grain. The following statement from Mr. F. 

 Symes, Grain Inspector, Fort William, explains how the material used 

 for these experiments was secured: —

 Dear Sir, 



I beg to advise you the carload of screenings which I obtained for the depart- 

 ment was taken from the Port Arthur elevator, Empire, Grand Trunk Pacific, and 

 the Dominion Government elevators at Port Arthur and Fort William. This would 

 represent screenings from each road, namely, the Canadian Northern, Canadian 

 Pacific, and Grand Trunk Pacific railways, and would be as representative a sample 

 of the natural screenings from western points as it would be possible to obtain. 



These screenings were not recleaned in any way, but came straight from the 

 cleaning machinery. It would be impossible to get a more representative sample 

 than that which I obtained for you. 



Yours truly, 



(Signed) F. SYMES, 



Inspector.
