Extensive strength testing has been carried out on poles of messmate stringybark both green and seasoned. The adequacy of the sampling has been established, and relationships have been defined between the strength of poles and that of small standard test specimens of the same species. It has been shown that for practical purposes the origin of the pole supply is not important and that the mean strength is not affected by pole girth. However, the variability of strength within girth classes is different, so that allowance for this should be considered in pole design. Basic working stresses for messmate stringybark poles are given with modification factors for special conditions of pole use.
