SAVING THE WOOD SUPPLY
BY Frederic J. Hsskin.

Iarninated wood construction was
greatly developed during the var by
the Forest Products Laboratory. In
plain language. II CONSISTS OF glueing
small pieces Of wood together 70 form

Wise working or using the largo piece

Clues have besn developed that are

waterproof and bacteria proof. Al

Using LamInated Wood,

mated wood will have a profound sTeot

ways than one. II will encourage tho
commercial planting OF forests by en-
