Based on the tests carried out on small clear specimens, the physical and mechanical properties of Mangifera indica, Dehra Dun (U.P.) and Syzygium spp., Dehra Dun (U.P.) are presented. Nail/screw withdrawal resistance, safe working stresses for structural purposes and suitability indices for different industrial and engineering uses of both the species have also been reported alongwith the corresponding values of Mangifera indica, Puri (Orissa) and Syzygium spp., Cachar (Assam) and also Tectona grandis (Malabar, Nilambur and Coimbatore) for comparison. The results have indicated that properties of both the species viz. Mangifera indica and Syzygium spp. tested from Dehra Dun (U.P.) are inferior in almost all the properties as compared to Mangifera indica, Puri (Orissa) and Syzygium spp., Cachar (Assam).- A Note on Physical and Mechanical Properties of Terminalia paniculata (Kindal) from Kerala

PhYSical and mechanical properties of Terminalia peniculata (Kindal) received from Karulai Range, Nilambur, Kerala tested in green condition have been reported and discussed. The results obtained have been compared with standard teak. It is found that values are lower than standard teak in general. Expected values based on the strength-specific gravity formulae have also been reported for comparison.- A Note on Insulation-boards from Jute Sticks

Investigations have been carried out on insulation boards with a view to evaluate suitability of jute sticks for fibre boards. Comparing the results of jute sticks fibre board with the rice straw board' it is observed that jute sticks fibre are stronger' stiffer and dimensionally stable than rice straw boards. As the results on these studies are quite encouraging' the jute sticks can be used as raw material' for making insulation fibre boards.- A Note on Physical and Mechanical Properties of Lagerstroemia speciosa (Jarul) from Kerala

Particle boards are hygroscopic in nature and has the tendency to absorb water from its surroundings and thus results in swelling, which in turn has great impact on its utilisation. In the present study an attempt has been made to evaluate the water absorption and swelling properties of some commercial particle boards. It has been observed that rate of water absorption is fairly high in the initial period of soaking and there is no appreciable change in lengthwise and widthwise directions as compared to the thickness of the boards. It is also observed that swelling is linearly related with water absorption.- A Note on the Jointed Wood Poles for Overhead Power and Telecommunication Lines

Although jointed wood poles are quite often used for overhead power and telecommunication lines specially in hilly and rural areas, only wire bound lap type of joint is commonly adopted. As tests data on other types of jointed poles described in concerned Indian Standard Specification, IS : 6056-1970 is not available, the same has been collected and presented in this paper. It is found that Z-type of lap joint is comparable to wire bound lap joint. While other types of joints taken in the study have come out to be inferrior to these two types of joints.- A Note on Physical and Mechanical Properties of Tetrameles nudiflora (Maina) from Assam
