MEANING OF FOREST AND FORESTRY 3 
the production of such conditions that the forest 
may grow to the best advantage for the purpose 
intended. 
Forest-culture, forestry, and silviculture are prac- 
tically synonymous terms. The term “silva,” in 
Latin, means forest, and in English is applied also 
to the forest-trees collectively of a region. We 
would say, for instance, that ‘“ the silva of the Pacific 
Coast consists mainly of conifers, or cone-bearing 
evergreen species, such as the redwood, pine, and 
‘ y) 
spruce.” The term “silva” is also applied to a 
descriptive lst of the forest-trees of a particular 
region or country, as Sargent’s Silva of North 
America. The term is in common use in the adjec- 
y) ‘ 
tive “ silvan,” in the term “ silvas,”’ which are large 
wooded areas in South America, and in the proper 
names Pennsylvania and Transylvania. The term 
“ b 
“ arboriculture,” from the Latin “arbor,” a tree, is 
applied to the growing of trees for any purpose and 
in any way whatever—singly, in groups, or in the 
form of forests. Silviculture is therefore a part of 
the broader art of arboriculture. 
Forests may be grown for other purposes than 
timber production, such as protection and adornment. 
Although, perhaps, the most important, wood is not 
the only important forest product. In the case of 
rubber or camphor, the wood is of minor importance.
