The paper in this publication contains a large 

 amount of hardwood fibers. This paper 

 represents a significant breakthrough in wood 

 utilization research. Until recently no 

 satisfactory pulping method was known for 

 the use of hardwoods. But through cooperative 

 research, the Forest Service and private 

 industry have developed a new process by 

 which hardwoods can be used in papermaking.
