296. The Need for a Study of Forestry. — We are using 
timber three times as fast as it grows. A study of a few 
minutes will show many 
of the uses to which wood 
is put which accounts for 
its great consumption. 
For instance, the paper 
on which you are writing 
was probably made from 
wood; the pencil which

depends for its success on the presence of woods or forests, 
(1) to insure a plentiful supply of rain, and (2) to hold it 
back so that it may produce a steady supply during the hot 
weather when rain does not fall often. Again, the covering
