REVIEWS AND NOTICES OF BOOKS. 85 



while Picea sttchensis of Alaskan origin has been a failure, but 

 it is hoped that seed from a different source will prove successful. 

 With Douglas fir, only seed from Quesnel, in the upper Fraser 

 valley, was successful. 



The investigator has found that, excepting the larches, Western 

 American trees coming from regions at suitable distances from 

 the Pacific are the most promising exotics. 



The English reader need have no fear of being unable to 

 gain any information from this book, since, although a large 

 part is written in Finnish, there is an excellent summary in 

 English, and each of the good photographic illustrations has a 

 description in English. 



The reviewer found much of interest, and can commend the 

 perusal of the book to all who are interested in attempts to 

 introduce trees to new countries. We think the author is 

 over-modest as to the wide value of his work, when he says that 

 " there is small hope of interesting foreign readers in this pioneer 

 work in the north." J. M. M. 



Northern Trees i?t Southern Lands. By Ernest H. Wilson. 

 Reprinted from the Journal of the Arnold Arboretum, 

 Vol. iv., 1923. 



The author has sent a copy of this Reprint, which contains 

 a summary of the observations made by him during a tour of 

 two years through South Africa and Australasia. Mr Wilson 

 discusses the economic value of many of our conifers when 

 transferred to the Southern Hemisphere, and the significance to 

 the future of the world's timber supply of the introduction of 

 many northern conifers on a large scale.
