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 kind 
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-
