Is the President of the Board of Trade aware that there is a great amount of interrogation in this House on the question of channel black? HON. MEMBERS: "Carbon black."] Carbon black is also channel black. Is the right hon. and learned Gentleman aware that there are interests in America who have a corner in this at the moment, and are very anxious to know if anything is being done to produce it in this country? I hope that if it is, no information will be given in that direction.
