According to Mr. Hutchins, in various most inter- 

 esting tabulations prepared by him, the following are the 

 estimated cubic feet of timber carried by different forests. 

 Timber in a normal forest of Scots Pine in Mid- 

 Europe at 1 20 years : — 



1st Class 

 3rd Class 

 The same at the age of ninety years : 



1 st Class 



2nd Class 



Maximum of the South African 



Yellow-wood Forests : 

 Mature forest of Aleppo Pine, Cyprus 

 Heaviest timber areas known, e.g., Red 

 Wood — California, Douglas Pine — 

 Oregon, Blue Gum — Tasmania = 100,000 ,, 



These are of course all forests of great and proved value. 

 Against these compare the East African forests. 



Southern Kenia forest = 2,100 feet 



W. Kenia forest = 3,265 ,, 



Mabira (Uganda) average sample area = 4,102 „ 



Average area " Eldoma Ravine" = 6,160 ,, 



Camphor forest, South-East Kenia = 7,945 ,, 

 Elgeyo escarpment maximum area 



coniferous timber = 15,000 „
