Single node cuttings from node one to ten of 6-8-month-old culms planted horizontally in March, ischolar_mained at the nodes. The bud of a cutting produced a dominant routed shoot and/or a cluster of precocious branchlets. Later some of the buds on the precocious branchlets also produced ischolar_mained shoots. Cuttings from the basal node of two and one-year-old culms, planted in July-August gave similar but subdued results. Some of the cuttings from the remaining culm lengths produced erratically reeoted shoots (i) by ischolar_maining of mature primary beanches (ii) from primary-branch buds with or without air-layering and (iii) from buds of precocious-branchlet stumps. The ischolar_mained shoots produced from their basal buds juvenile culms, each with typical neck and rhizome.- The Wattle-bark - Acacia mollissima Willd., Monthly Variations of Tannin Contents

The article describes pilot plant trials of the two stage process of Katha and Cutch production recently developed in the Chemistry of Forest Products Branch of this Institute (Indian Forester, 1965,91 (1), 67). Total yield of katha and cutch obtained are 9.35 per cent and 5.66 per cent respectively on the oven dry weight of the heartwood.- Studies on the Suitability of Origanum vulgare Seed Oil in Paint and Varnish Industry

The seed cake left after the extraction of oil from the kernels of Sapindus, ukorossi Gaertn. (soap nut) has been analysed. The cake is found to be rich in Nicrogen content. Qualitative tests indicated the presence of alkaloids and starch in the cake. The teste for tannins and sugars were negative. The results of the analysis are presented in the note.- Further Studies on Distillation and Utilisation of Oleo-gum-resin of Boswellla serrata (Roxb.) (Salai)

Salai (Boswellia serrata Roxb.) gum was distilled by two processes, viz., (1) Steam distillation and (2) Solvent extraction followed by steam distillation and the three components, viz oil, gum and rosin were separated. The components were analysed for their physico-chemical properties. Experiments were also carried out to explore the possibilities of utilizing the Component,parts industrially and the possible uses are indicated. The results are described in the article.- Studies in the Chemical Composition and Possible Utilities of Soap-Nuts (Sapindus mukorossi Gaertn.)

The pericarp and the shell of soap-nut fruits have been chemically analysed. The pericarp has been found to contain water solubles as high as 74.20% while shells have been found to be rich in crude fibre. The kernels on expulsion yielded 24.0% and on solvent extraction 38% of the oil. Samples of soap were prepared using this oil. The exhausted cake was used as a filler in the soap preparation. The pericarp powder and the samples of soap prepared were found to have good cleaning properties.- Note on Catechin of Acacia catechu (Khair Wood) and Effect of some Food Additives on its Coloured Solutions
