The expanding use of wood pulp and pulp products has emphasized the need for increased basic knowledge dealing with the waste materials and by-products of the forest industries. Wood bark is one or the major byproducts. In the paper industry alone millions of tons of bark are discarded annually and as a result have created an ever growing disposal problem. Investigation has already broadened knowledge as to the physical and chemical properties or this waste material and a beginning has been made in putting it to economic use. A series or investigations conducted in the Division or Industrial and Cellulose Chemistry has been concerned with discovering as much as possible about the chemical composition or bark.
