ARTIFICIAL FORESTS OF EUROPE 



tion it is in some respects like the cop- 

 pice; for, as in that type, there is a 

 uniformity of size in the trees on re- 

 stricted areas, and the species that 

 compose the entire forest are very lim- 

 ited in number. Coniferous high for- 

 ests, which are the most common, are 

 often composed of only a single Mnd 

 of tree, and broadleaf forests of the 

 same type rarely contain more than 

 two or three species. These forests, 

 like the coppice, comprise a full com- 

 plement of sizes and ages, each con- 

 fined to a separate section; but the 

 steps are not single years, as in the 

 coppice, but periods of ten or twenty 

 years, or even more; so that the high 

 forest, above all, is a much taller and 

 older one. The sections that com- 

 pose it are not regular in outline, ex-
