THE LARCH. 



Lhrix eii7'0pa:a. 



The Larch which is extensively planted in parks and lawns 

 is not the American species but the European. The Euro- 

 pean Larch is the liner tree in general appearance and as it 

 naturally prefers loose well drained soil it flourishes where 

 our native species would die. The leaves are longer, they 

 clothe the branches more generously than those of the Amer- 

 ican species, the cones are larger and more abundant. It is 

 a tree of the mid-temperate regions as well as of the north 

 and is found in all the hill country of central Europe and 

 forms large forests in the Alps of France and Switzerland.
