I sympathize with my hon. friend on that point. I believe the tailings of screenings that come from the elevators at Fort William and Port Arthur are the principal media for the distribution of these foul weeds. These tailings or screenings are bought by the millers of Ontario, mixed with other grains, ground, and sold as feed, but they are not ground sufficiently fine to destroy all the weed seeds. It is a problem worthy of consideration whether something ought not to be done to restrain the distribution of these screenings. It is a matter which is under my consideration and which will have to be discussed in dealing with the terminal elevator question.
