cording to Deggeller. He emphasized that end-use satisfaction is a factor of great importance as the plywood industry faces added and keener competition from other building materials.

Harbor has many "firsts" to its credit. In its ou,'n laboratories in 1934, Harbor perfected the first completely rvaterproof adhesive and used it in their Super-Harbord. It is still recognized by boat buiiders throughout the country as the leading exterior fir plyrvood. This type of panel opened new markets not previously available. As a result, at a later date, glue manufacturers produced similar adhesives and others in the industry began marketing waterproof plyrvood. During World War II, the entire production of Super-Harbord rvas allocated to demands of the military service.

Harbor also led tl-re way in the production of overlaid fir plywood. HARBORITE, a medium density resin-impregnated overlay panel using SUPER-Harbord as the core body, was the first overlay panel in the industry and lvas developed in the Harbor laboratory in 1938. Since that time, other fir plywood manufacturers have produced similar type panels, on a royalty basis, using overlays produced by other manufacturers.

Some of the principal advantages of HARBORITE, in addition to its thoroughly waterproof qualities, are the virtual elimination of grain-raising and checking of the wood fibers when subjected to natural weather conditions.

The industry is experiencing a rapid increase in demand for this type of product, due in part to Harbor's extensive promotion and marketing campaign through their own distribution warehouses and carefully selected distributors throughout the country.

Field promotion men and an extensive national advertising campaign on HARBORITE, directed principally to such end-uses as boats, outdoor signs and displays, concrete forms and the construction industry, are accounting for a substantial part of Harbor's production.
