The history of the introduction of the genus Eucalyptus in the Indo-Pakistan subcontinent dates back to 1867. Since then a large number of species have been tried in nurseries as well as in plantations. The number of species which have been planted in different areas is somewhat limited the most common being Eucalyptus tereticornis and Eucalyptus carnaldulensis. According to Parker (7), Eucalyptus tereticornisisthe most common species found in the Punjab and with the possible exception of Eucalyptus rudis it has the fastest rate of growth. It has been tried in Andaldal Plantation of Shikarpur Forest Division and in Daphar Plantation of the Gujrat Forest Division. Pure stands of Eucalyptus tereticornis are found in several places in Abbottabad and Changa Manga. On account of its adaptability to a wide range of climatic conditions and its past performance in Africa and India, it has been recommended by Pryor (8) that this species should be preferred keeping in view the overall needs of timber for various end-uses. Like other phenomenon in the universe, trees also require a systematic study. The growth of the trees is influenced by a number of factors involving a study of physiology, ecology and the silvicultural practices. But the foremost consideration which determines their commercial exploitation for various purposes is the basic information about their technological properties. The lack of such information about the home grown species has always been a serious setback in their proper utilization. An investigation on the technical properties of Eucalyptus tereticornis was therefore undertaken in order to provide reliable data often required for determining its utility. The present study is just a beginning of the work on the mechanical properties of some of the relatively uncommon timbers grown in Pakistan. Although this study is based on the material from only one locality, it is planned to extend this work to material growing in other areas as well.
