Fig. 21. In many places tbe beach presents a half naked condition varying in width from 

 ten to eighty rods between the high water mark and the foot of the established dune. There 

 is plenty of space on such areas for the planting of heavy foliaged conifers which will 

 strengthen the protective cover of the dune and produce valuable timber.
