After a gonerM i n t r o d u c t i o n dealing with a n a l y s e s of l a m i n a r ~ d turbulent, air-flow, t h e Roynold n u m b e r , m e a s u r e m e n t e q u i p m e n t a n d its technical utiIisation, etc., the ecologist will be v e r y interested in t h e c h a p t e r headed " C o n t r o l of wind in e x p e r i m e n t a t i o n and ma a ~ l y ~ i s of w o r k w i t h w i n d - t l m n e l s " . I n o u r opinion, definitions of laa~nlnar and t u r b u l e n t air-flow should h a v e bee.n t r e a t e d m o r e precisely. Of particular in%crest in P a r t 2 are the chapte.~ " E n e r g y balance mad surface temperaturea*~, " E f f e c t of wind on w a t e r u s e " w i t h a practical d e m o n s t r a t i o n of m e a s u r e m e n t s , and finally the r e m a r k a b l e c h a p t e r "Effect of wind on p h o t o s y n t h e s i s " , whleh, however, would have de, e r r e d m o r e detailed t r e a t m e n d j e.g. t h e effect of wlnd-speed on t r a n s piratlon rate a n d n e t p h o t o s y n t h e s i s as regards t h e individual species. I~art 3 contains chapters on g r o w t h rate a n d the results of w i n d - t m m e l e x p e r i m e n t s w i t h an instructive figure showing tho effect of wind o n the g r o w t h rate of Brassica napus a n d P ~ u ~ ~vliyam, and a table o n the effect of wind e n d sell moisttu~ on t,he g r o w t h of Robinia pseudoaoaci~. Of great interest are t h e results of t h e direct influence of wind (e.g. effect of ,,exposure*' u p o n t h e s t r u c t u r e of Pier]diem aquilin~rn, etc.). The c h a p t e r on wind s w a y a~nd plant stability deals with the response of s t e m form Lo s w a y i n g ~nd explain~ the influence of s w a y nn ~he distrib a t l o n of the wood i n c r e m e n t in the st~r~ of Lerrdx lari~fz~a.

According to the at~thor, "t~xamples of' practical Twoble~ns in crop science w h i c h t~quit'e an undt~rst.andlng of p~wtitde behaviour: I n Iand eonsc,~rvation studies --. u l s t e r w h a t conditions does wind erosion o f soil ~'~eeur? . . .

I n the chapter "Tree g r o w t h in m o u n t a i n o u s a r e a s " , the effee~ of wind on trees is divided into these categories: bm~shing, flagging, wind clipping, tree c a r i ~ t s , winter killing, resurgence a n d ice deformation.
