Fig. 20. A dense mass of mixed hardwood and conifer growtli of fifteen years at Prank- 

 fort on tiie dune property of II. A. Lewis. Sucli a cover becomes a splendid insurance against 

 sand blow damage and materially increases the value of the land. 



Fig. 21. In many places the 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.
