observation. Attention is drawn among other things to the 

 remarkable growth of certain eucalypts and pines, which 

 frequently attain a height of over 70 feet in 10 years with 

 proportionate diameter increment. The development of 

 afforestation in the various provinces is dealt with, and mention 

 is made of the principal species which are now being used, 

 together with the main objects of management, such as pre- 

 vention of soil erosion, protection against drifting sand, and 

 so forth. The article is suitably illustrated, and gives an 

 excellent survey of silvicultural activities in the Union. 



Mr W. A. Davie, of the Department of Agriculture and 

 Forests in the Sudan, describes the initial stages of experiments 

 with Acacia arabica in the vicinity of Khartoum. A particularly 

 interesting point which he brings out is that the seedlings of 

 this species withstand complete submersion for a period of four 

 or five months without injurious effects, and make rapid growth 

 subsequently. The plantations were laid down primarily with 

 a view to supplying firewood, but their success engenders the 

 hope that larger timber will ultimately be available, for which 

 locally there is a ready market, the original forests of the 

 district having entirely disappeared. 



Believers in the formation of shelter-belts for the improvement 

 of crops and the protection of live-stock, will find confirmation 

 of their views in an article by Mr F. W. Foster on forestry 

 in New Zealand. Mr Foster also gives particulars of the 

 progress of afforestation in the Dominion. 



Under the heading "Empire Timbers at Wembley," Mr 

 J. S. Corbett describes the principal timbers which have been 

 on view at the Exhibition. He draws attention not only to 

 the forest products of each of the Colonies and Dependencies, 

 but also lays stress on the necessity for developing the pro- 

 duction and sale of Empire woods. Many foresters who have 

 visited the Exhibition will appreciate Mr Corbett's remarks, 

 when he says that confusion has arisen owing to the peculiar 

 and in many cases contradictory trade names applied to 

 commercial timbers. For example, one finds the timber of 

 a certain tree bearing several trade names, or, on the other 

 hand, timbers of entirely different species labelled with one 

 name.
