which so clearly reveal themselves in a 



mountainous region are here less readily recognized. Of course 



none but waste lands are forested and wood production has been 



the leading motive; protection from high winds and from shifting 



sands have nevertheless been recognized as secondary advantages. 



The region along the west coast and the sterile country south and 



southeast of the Zuider Zee has been the scene of the mose active 



planting. Plantations dating back to 1870 may be seen in Gelder- 



land and Utrecht. The largest forest nursery is at Zundert near 



Breda. 



A mutual betterment association of owners of heath land, the 

 Heath Society, was the only organization interested in forestry 

 during the nineteenth century. It carried on a campaign of edu- 

 cation and encouraged forest planting until in 1898 a state forest 

 service was organized. Now both work hand in hand. There is 

 danger that before their work stops the last picturesque Dutch 

 heath will be reclaimed.
