1936

Experiments have shown that in plantations where the first thining has been delayed the trees of the future often occur in groups and the number of good stems per acre is much less after thinning than where the first thinning has been done in time and trees of the future have been selected by the marking officers and not by nature. [...] The first thinning should aim at the equal spacing of selected straight dominants by the removal of wolf forked badly cankered misshapen"32 and diseased trees and in addition certain good domnants in order to give full room for the development of the crowns of the selected trees. [...] The second thinning will be fairly heavy D " grade and the points to remember are exactly the same 'as those mentioned for the first thinning that is the even spacing of selected straight stems by the removal of badly cankered wolf forked diseased and misshapen stems and in addition the removal of good dominants in order to give room for full crown development of the remaining stems. [...] For the above reasons it is the opinion of the writer that the first thinning should therefore be carried out before the natural selection of dominants have taken place and experience has shown that dense line sowings of panisaj of good growth requires thinning in the third or fourth year on the more sandy sites in parts of the Kalimpong Foot Hills in the fifth or sixth year. [...] The first thinning should be a heavy " grade and will consist of the even-spacing of selectedtlominants by the removal of all badly shaped wolf diseased and forked stems and in addition the removal of good dominants so as"37 to give the selected stems room for proper crown deveopment.
