 968. 1919.— Afforestal Lon is i he key to soil conserval ion, and it is possible to make it effective 

 in many localities where meantime soil conservation is badly needed; nevertheless affore 



t ion and soil conservation belong to Beparate, and usually widely separated districts, the for- 

 mer only acting to the other district as the transmitter of the moisture which it requires in 

 order to grow and maintain ;m efficient vegetation. Afforestation is a matter of the first 

 importance, indeed it is the controlling factor as to whether or not the suh-cont inent shall 

 remain for long habitable enough to permit of the community dealing much further with all 

 or any of its other "burning subjects." — E. P. Phillips.

 pheric conditions have been retarded or suspended." — G. B. Rigg.
