OF A.{Mr Adams} Kindly note we have tested a sample of Bone Grey Fibre against our present Red Fibre, by placing a piece in water, and after leaving for several hours, we found the Bone Grey Fibre was quite plastic, and we are of the opinion that the only difference between the Bone Grey Fibre and the Red Fibre is the Colour.
