The many facets of forest planning make it, at any time, a difficult task. Additionally, what often remains unrecognised is that the forest "capital" is liable to respond to the same saving-investment-output relationship that characterises all economic development activities. Thus, unless the capital base constituting the forest itself is expanded, or the production technology is improved, growth of output cannot be possible. For achieving this, appropriate reallocation of the present use to which skilled manpower and related resources are put, is essential. It is the thesis of this paper that only a planner with a deep concern for the future, possessing the necessary "vision", can take appropriate steps in this regard. To highlight the importance of this attribute in forest, development a relatively simple method of graphic presentation and analysis is followed. This makes it possible to articulate the various effects which different levels of the planners' "vision" can have on the state of forests and their secular development, given the consumptional preferences of the society. Like any other theoretical enquiry, the analysis only helps in drawing certain possibly not immediately obvious, conclusions from alternative sets of hypothetical assumptions.

Studies of price and quantity movements of internationally traded commodities are highly sensitive to the choice of the time period Yet, the long-term trends displayed by those movements are quite capable of yielding information valuable for short to medium-term export policy formulation. Attempts are therefore, made in this paper to ascertain the directions, relative magnitudes, and policy implication of the secular shifts of the demand and supply curves of fourteen selected Indian forest-based exports, as implied by their observed unit value/price and trade volume growth trends.The results reveal that the outward rates of secular shift i of the demand and supply curves of printing and writing paper are probably the highest, and those of paliwood logs, with their inward shifts the lowest among the exports studied Though undue importence cannot, it is acknowledged, he attached to the numerical magnitudes of the estimates made, their ranges and relative rankings do provide the basis for several conclusions. A diagrammatic exposition, provided in the appendix, further clarifies some of the observations- The Role of Forestry in the Indian Economy

An attempt is made in this paper to empirically evaluate the role played by forest commodities as producer goods in the Indian economy. This role is appraise in terms of their impact on material production employment generation, and the achieyement of self-sufficiency. A formal model, on which the analyses are based is first introduced. The relevent methodological aspects are presented and the resu1ts are discussed. The possible contributions that the Forest Corporations could make are also highlighted, in the light of the appraisals made.- Employment Potential of Forest-based Industries

Among the objectives of the present economic and industrial policies that tend to attract attention are the twin goals of employment creation and, through it, the improvement of income distribution in the society. Although foresters have long recognized the role that forest-based industries could play in this respect, no comparative assessment of product-wise potential of fulfilling these objectives appear readily available at present. In this paper a "micro-study method" for estimating the direct and indirect, total labour and other factor generating potential of industrial (or other) activities is thus described and applied to nine forest-based commodities. The ex-post study reveals that the safety match industry appears to posses the greatest employment creating potential per unit value of output at producer's price, and particleboard the least. The remaining forest-based industries are also ranked on difFerent criteria adopted for the purpose.- Single Factor Analysis-A Decision Criterion for Forestry Operations

Tending and cultural operations are generally considered essential for raising successful forest plantations. Despite this realisation the foresters' earnest endeavours are' however' sometimes frustrated by several limitations of which the 'paucity of funds' may perhaps be the singularly important one. An appraisal of the causations reveal that budgetary constraints arise primarily as a consequence of the quest for present investments aimed at increasing future returns' when fiscal rationality demands that selection among alternatives be directed toward maximisation of the net present value of the outcome. Since forest plantations are necessarily investments for the future' the expenditure on connected activities ought logically follow similar financial considerations. Single factor analysis' which weighs cash outflows necessary for rectifying a particular deleterious situation against the expected cash revenues' provides a convenient meaas' in such cases' for arming the forest administrator with a quantitative basis for deciding what' if any' should be the funds allotted for various related operations. Additionally' the technique also provides a rationale for evaluating the alternatives' where they do exist. In this paper theoretical framework is developed to assess the financial impact of one of the tending operations' namely weeding and cleaning' in forest plantations. The model is applied to a typical teak plantation of the hypothetical locality of Norgalia where fiscal constraints generally preclude this operation' though often considered necessary' beyond the first three years of creation. The results reveal that the investment embodied in additional weeding and cleaning is highly profitable and thus rationally speaking' there should be no 'paucity of funds' for the purpose.- Forest-based Sectors and Interdependence in the Indian Economy

Foresters in India have long realised the importance of forestry and forest-based sectors in the national economy. No quantitative information of this interdependence, however, appears to be readily available at present. Apart from its appeal to the professional as a curiosum, this knowledge could be essential in the context of planned economic development as well. In this paper, an attempt is made to empirically analyse the role of forest-based sectors, in value terms, in the different producing sectors of the Indian economy. The theoretical aspects are presented and the results of the analysis are furnished. Lastly, their application in development planning is also discussed in brief.- The Long-run Implied Income Elasticity of Demand of Forest-based Products in International Trade

The "income elasticity of import demand" is a key concept in international trade in as much that it enables an identification of commodities expected to experience rapid growth in world trade. In this article a theoretical basis for estimation of the parameter is discussed and the methodology is applied to thirtyseven commodities (including eleven forest-based products) of interest to exporters in India. The results reveal that the income elasticity of demand of forest based products in world trade is high. A consideration of the income and price elasticities of import demand indicate that the forest-based esports may be expected to ahieve very high growth rates ia the future. It is evident that it may be worthwhile for India to concentrate in these commodities as future foreign eschange earners for the country.- Structural Pattern of Rocks Around Dariba, Alwar District, Rajasthan, with Special Reference to Copper Occurrence

The structural pattern of Delhi system of rocks around Dariba is dominated by open, asymmetrical folds which occur on both major and minor scales. A set of axial plane cleavages, which grades from discrete fractures to slaty cleavage, is consistently developed with the folds. The axial traces of the major fold range in trend from NNE-SSW to WNW-ESE. Although the fold axes vary both in direction and amount of plunge, the axial planes are consistently inclined westwards. The copper ore bodies which have been explored so far, occur in the eastern ridge of Dariba. Mineralisation is practically confined to phyllites ana schists. The lenticular ore bodies have been explored uptil now on the limbs of major overturned synformal fold in the eastern ridge. The axial plane cleavage has been observed to be the main structural plane controlling the distribution of the disseminated sulphides in the rock.- Ore Microscopic Observations on Sulphide Minerals from Dariba Copper Mine, Alwar District, Rajasthan

The Chotanagpur gneiss-Granulite complex (CGGC)-a mobile belt north of the Archaean Singhbhum cratonic nucleus and contiguous orogenic belt with the Singhbhum Proterozoic basin, is a vast tract of high-Grade rocks and gneisses with enclaves of granulite and metasedimentary rocks, and intrusive granites of Proterozoic age. Pervasive intrusions of mantle-Derived rocks of varied composition ranging from mafic-Ultramafic, sodic-Ultrapotassic alkaline rocks, massif anorthosite to younger tholentic basalts (Rajmahal) and dolerite at different geological periods ranging from Late Paleoproterozoic to Early Tertiary, give evidence of an active mantle in the prolonged history of evolution of this mobile belt. The present study is limited to metamorphosed mafic-Ultramafic rocks at the eastern sector of CGGC. The mafic-Ultramafic suite is represented by amphibolite, basic granulite and hornblendite. Compositions of the primary amphibole in these rocks range from hornblende to pargasitic hornblende, and plagioclase from An40 to An59. Positive correlation of Mg# between clinopyroxene and hornblende, and clinopyroxene and orthopyroxene, indicating that the Fe-Mg exchange KD is constant between the ferromagnesian minerals, and the rocks to have attained equilibrium conditions of metamorphism. Calculated post-Peak metamorphic equilibrium pressures and temperatures are 3 8-5 4 kb and 643- 781°C, similar to conditions in the surrounding country rocks.
Chemically, the metabasic rocks studied are associated with the Bengal anorthosite massif at Saltora and have been grouped into low-Ti and high-Ti tholeiites. The former shows similarity with transitional basalts derived from T-MORB, while the latter is rich in incompatible elements and shows affinity with basalts derived from E-MORB or from recycled mantle fed by subducted oceanic crust. The nepheline normative ultramafic rock is the most depleted in incompatible elements and shows similarity in trace element contents with MORB. All these rocks show variable crustal contamination. Nevertheless, the bulk chemical compositions of the low-Ti rocks preserve evidence of low-Pressure fractional crystallisation involving olivine, plagioclase and clinopyroxene. The intra-cratonic Mesoproterozoic bi-Modal (tholeiitic-alkaline) magmatism in CGGC is analogous to Phanerozoic magma generation(Rajmahal tholentes-Ultrapotassic mafic-Ultramafic intrusions in the Gondwana basins) in a rift setting (Damodar graben /Shield margin faults) accompanied with crustal thinning. The trace element geochemistry of mafic-Ultramafic rocks gives evidence of plume-Generated magmatism in the Eastern Indian Shield margin during Mesoproterozoic time, which is correlatable with the global thermal event in the Precambrian shields.
