The purpose of this research was to test the difference in strength and stiffness of red pine poles cut from natural stands as compared to plantations, when each group was selected in accordance with A.S.A. standards. The following conclusions were derived:

1. There was no significant difference in the bending strength of green red pine poles grown in plantations or in natural stands as second growth trees, if selected according to ASA 05.1-3-1963.

2. There was no significant difference in knot diameters in the two groups of poles selected under ASA 05.1-3-1962

3. Circumference at ground line was found to be a valid predicting parameter for pole strenght.
