 leaved British forms reverts to the type, and is a statu probably 

 equivalent to the barren autumnal growths of some heterophyllus-

 the coriaceous floating leaves sometimes produced by nitca* in deep

Enough has now been said to show how much interest this 

 beautiful series of plants has for British botanists. Two more 

 parts of fifty sheets each will complete the work, which will then 

 offer a standard for reference, or comparison with Potamogetons

 The appearance of a translation of Hartig's valuable book is 

 made more opportune by the eloquent appeal on behalf of British 

 forestry in the recent address of the President of the Biological 

 Section of the British Association. There can be no doubt that 

 many of the facts and arguments of that address called for as wide 

 advertisement as might be made, and to a nation distinguished by 

 ■ . : 



claims can hardly be made in vain. It is, however, lamentable 

 that lovers of sylvan beauty do not exclude the "blasted pine" 

 and "withered monarch of the forest" from their catalogue of 

 aesthetic charms, and there are many who transcend even Mr. 

 Auberon Herbert in regarding a forest as a mere arena for plant 

 strife without a forester to see fair play ; whose aesthetic ideas are 

 moreover as mixed as their metaphors. Such extreme views com- 

 monly proceed from ignorance of forestry and its metiiods, and are 

 based on the absurd notion that a wood tended by a forester is a 

 place swept and cleared of litter, and garnished with metal labels 

 and announcements hinting at " thirty shillings or a month." 

 However, such anarchists are fortunately in the minority, and 

 lovers of nature care as little to see a sickly or wounded tree as an 

 afflicted animal. The increasing number who regard forests from 

 the economic point of view are, however, those to whom this book 

 makes its special appeal, and it helps to make it clear that we must 

 look primarily to botanists for their share in the care and manage- 

 ment of forest affairs.
