Pacific Coasts and along inland lakes and rivers now covered with 

 dunes become more valuable, our government will of necessity pass 

 laws and expend large sums for their holding and planting, as 

 France, Germany, Holland, Denmark and other countries have been 

 forced to do. 



The great need at present is a definite knowledge of the dunes as 

 they exist in different parts of the country. There must be more 

 accurate data as to the origin of the sand, which is forming a cer- 

 tain group of dunes, of the process by which the dunes are being 

 formed, of the amount of plant food which the sand contains, of the 

 moisture in the sand and its source, and lastly, and of most impor- 

 tance, of the flora of the dunes. From this knowledge it will be 

 comparatively easy to plan as to where the sand shall be held, 

 whether in the form of a protective dune or at the place of its origin, 

 and what methods of work will be most practical.
