Figure 23-4. — Schematic illustration of the advantage of single-species furnish in the 

 manufacture of fiberboard, compared to a varying and uncontrolled mixture of spe- 

 cies. A fiber furnish from a closely controlled, unvarying, homogenized mixture of 

 species can yield a product with a narrovtr range of properties, however. (Drawing
