58. As regards all species other than the four above enumerated, the 

 exploitable trees should generally be cut in the main fellings, the only restriction 

 being as regards the minimum girth provided for each species. 



Forecast of the condition 59. Turning to Appendix IV we have at present 



of the crop at the end of the the following number of trees in the 1st four 

 cutting period. classes : 



We have no means of estimating the loss of trees of each species while 

 passing from the II to the I class, as class I is abnormal, it is therefore taken as 

 20 per cent, for all species. For the lower classes the percentages of loss are 

 deducted from 



the actual figures as follows : 



Sound Matti while passing from class Til to class II 12 per cent.

01. Now at the end of the present felling period of 40 years we shall have 

 removed all class I -|- ^ of class II, that is all mature trees and half the 

 number of trees of class II which come over in front of the fellings, and as only 

 half tlie total number of class II do come over in front of the fellings, we shall 

 have cut | of class II as stated above. As it takes 40 years approximately for 

 class II trees to become class I, at the end of the felling period we shall 

 have f of the present class II, minus the number lost during transition, 

 i. e., 20 per cent. 



62. If the 2nd felling period is again fixed at 40 years the number of stems 

 available for felling during that period will be all the mature trees, namely, | of 

 the present class II minus 20 per cent, which will then have become class I as 

 well as the trees that come over in front of the fellings from the lower 

 classes. 



63. As all the Matti, Nana and Kindal of class III and all the Jamba class 

 IV. become class II and class III respectively during the next 40 years, and as
