It is not added to butter in the dairying district that I represent. More than that, I find in Hansard a statement that colouring is not added to butter. That would appear to be borne out, because we find the manager of this factory saying: "We made it a special object to buy June butter because that was more highly coloured." If I am wrong in that respect, I am wrong; but that does not affect the question of the colouring of oleomargarine. I am not aware that any agricultural industry ever offered to pay the Government 10 cents a pound for the privilege of colouring.
