Professor Warming, who was the first to undertake 

 a systematic study of plant-communities, is still living, 

 and his work The Ecology of Plants is a classic among his 

 followers. A. G. Tansley's Types of British Vegetation 

 is an excellent guide to British workers. It contains 

 contributions from various members of the Central 

 Committee for the Study and Survey of British Vegeta- 

 tion. 



Here we leave the subject. To have considered it 

 in closer detail would have taken us beyond the limits 

 of the present volume. Our treatment has been in- 

 adequate, but we trust we have indicated, in brief 

 space, what plant-ecology is and how comprehensive is 

 the scope of the " new field-botany."
