should be utilised by being planted with it. By so doing, the 

 plantations ultimately formed would not only be of value 

 commercially, but would greatly improve the various districts 

 from the aesthetic point of view. 



EXPLANATION OF FIGURES. 



(Plates IV. and V.) 

 Fig. I. Comparative height-growth of Corsican (left-hand curve) and Scots 



(right-hand curve) pine at all ages. It will be seen that Corsican pine 



leads throughout, and that height-growth was fairly steady after 5 years ; 



in the Scots pine increased height-growth only began after the 8th year. 

 Fig. 2. Graphic Representation of Diameter Increment of Corsican and Scots 



pine at 5 ft. from the ground up to 19 years of age. From this graph 



the increment for any period desired can be obtained. 

 Fig. 3. Stem Curves at the several stages throughout the life of the two types. 



6. The Empire Forestry Journal. 



The first number of the second volume of this Journal, the 

 official organ of the Empire Forestry Association, has now 

 appeared under the editorship of Mr Fraser Story. The 

 editorial notes deal with a variety of subjects and are followed 

 by an account of the first annual meeting of the Association, 

 when His Royal Highness the Prince of Wales delivered his 

 Presidential Address. The nominations for election to the 

 Governing Council are given, and these, although perhaps so 

 numerous as to make the Council somewhat unwieldy, never- 

 theless indicate growing strength and personality in the 

 Association. 



Mr R. N. Parker, of the Research Institute, Dehra Dun, 

 gives the first of a series of articles on the Indian Forest 

 Department. He deals with the foundation of the Department 

 by Lord Dalhousie in 1855, and gives an interesting account of 

 the constitution of the forest service and of its work of 

 conservation and management. Important work is now being 

 carried out in India with regard to the utilisation of subsidiary 

 timber trees and less known species. At the Forest Research 

 Institute itself research in papermaking (from bamboo), in 

 creosoting and seasoning of timber is being carried out, and in 

 several provinces local silvicultural research is in progress.
