FORESTS, FOREST TREES, AND AFFORESTATION IN CHOSEN. 5 I 



there is not one really hardy at the Arnold Arboretum in 

 Massachusetts; and whereas many Chinese and Korean trees 

 are growing well at the Arnold Arboretum, it is deplorable how 

 few of the splendid eastern American hardwoods do well in our 

 1 ountry. 



It is much to be hoped that the seeds we have received of 

 Mr Wilson's collecting for two years past in Korea will in time 

 enrich British collections with many fine trees from that region. 



What Mr Wilson says in his last paragraph of the desirability 

 of native trees for re-afforestation purposes must have been 

 written with eastern America in his mind. We would be badly 

 off indeed in Scotland if our planting of conifers was confined 

 to that of Scots pine, and the people of South Africa and Chile 

 do not regret the introduction and general planting in those 

 countries of Australian gums, and the Californian Finns insignis 

 and Cupressns macrocarpa. The finest coniferous woods of 

 1'ortugal consist of Cupressus lusitanica, introduced from Mexico 

 400 years ago. F. R. S. Balfour. 



6. Damage to Vegetation by Smoke and Fumes 

 (The Selby Smelter Commission Report). 



By A. D. Richardson. 



The report of the Selby Smelter Commission, ot which 

 Dr Lauder has given us such a lucid digest in the July part of 

 the Transactions, is no doubt a valuable contribution to a 

 somewhat meagre literature on a very important subject, and 

 although in this case the injury was to vegetation generally, and 

 not to silvicultural crops in particular, the report is none the less 

 interesting on that account. I think, however, that as Dr Lauder 

 seems to consider the procedure in this case greatly superior 

 to ours, and has introduced some remarks regarding our present 

 methods in investigations of this sort which, coming from the 

 Consulting Chemist to the Society and a scientist of his standing 

 and ability, might tend to prejudice unduly readers of the article 

 against them, what he has said should not be allowed to pass 

 unnoticed, and I now wish to say a few words in defence of our 

 procedure, and to show, so far as I am able, that it is not 

 quite so defective as one might be led to believe from the very
