balance between root and leaf, and also improves the subsequent cha- 

 racter of growth of the tree. 



The experiments show that under favourable conditions a tree will 

 adjust itself to almost any kind of treatment and still make a good tree.

 of railway slopes and stations for floral decoration, with special reference

Ranunculus, Alpine Species of. By C. Wolley Dod (Gourd. Mag. 

 No. 2526, p. 196 ; 29/3/1902).— A selection is made in this article of 

 the best species for the garden from a genus largely abounding in weedy 

 plants. The term " Alpines " does not necessarily mean dwarf plants, as 

 R. aconitifolius and R. platanifolius, both growing knee-high, are in- 

 cluded. The useful information that Mr. Wolley Dod always gives in 

 his writings makes this a very readable article, as this garnishing gives a 

 new interest to these simple mountain flowers. — W. G.
