which vegetation becomes established is along the shore line 

 and the vegetation tends to drift or spread from thence inland 

 in the direction of the prevailing winds. The work now 

 under way, however, has been started in localities some dis- 

 tance from the shore, and in any effort of the vegetation to 

 spread naturally it must do so in part against the wind. 

 Doubtless the immediate binding of the sand in the worst 

 places is the main object to be considered, but when that has 

 been accomplished the method indicated by nature should be 

 carefully noted and utilized as far as possible. The attempt 

 to work from the interior back to the shore is certainly in op- 

 position to this method. 



In accordance with environment the vegetation may be 

 divided into two main groups : that of the forested areas and 

 that of the bare sands : The bulk of the trees consists of 

 Pinas rig/da Mill., jgjiercus rubra L., and J^. velutina Lam., 

 with scattered patches and individuals of Bctula populifolia 

 Marsh., Fagus Americana Sweet, Primus serotina Ehrh., 

 Acer rubrum L., and Nyssa sylvatica Marsh. 



The underbrush is largely Viburnum venosum Britton, 

 Gaylussacia resinosa (Ait.) T. & G., Vaccinium Pennsyl- 

 vanicum Lam., Kalmia august if olia L., Rhus co-pall ina L., 

 Prunus maritima Wang., Amclanchicr Botryapium (L. f.) 

 DC, Aronia arbutifolia (L.) Medic, A. nigra (Willd.) 

 Britton, Rosa lucida Ehrh., and Myrica Carolinensis Mill., 

 and in the low swampy areas, Clcthra alnifolia L., Azalea 

 viscosa L., Ilex glabra (L.) A. Gray, Spiraea tomentosa and 

 S. salicifolia L. Arctostaphylos Uva-Ursi (L.) Spreng., is 

 omnipresent, which, together with Corema Conradii Torr. 

 and Rubus hispid us L., are important factors in the formation 

 of a close, coarse vegetable turf or mat, which covers and pro- 

 tects the sands in semi-denuded areas. Agrostis hyemalis 

 (Walt.) B.S.P., and Danthonia spicata (L.) Beauv., occur in 

 sufficient abundance, along the borders of and in the more 

 open woods, to attract attention, while the remaining her- 

 baceous vegetation includes, as prominent elements, Pteri- 

 dium aquilinum (L.) Kuhn, l^olygonum scandens L., Aralia
