slowly killed. The two dead oaks in center were probably killed 

 by an increase in the amount of moisture in the soil. In fore- 

 ground to ri{^ht is shown the low vegetation of the marshy strip. 



In addition to the trees mentioned above as occurring on the 

 inward faces of the dunes, others may be found in the best pro- 

 tected situations. These are Qiicrcus laurifolia (laurel oak), 

 Salix fluviatilis d^wd Jiiiii penis virginiana. The only fern discov- 

 erable here was the ubiquitous Ptcridhnn aquilimim. 



As the narrow western end of the island is approached the 

 dunes become sharper and higher, the palms disappear, and the 

 forest gradually runs out into a lower hammock growth, disap- 

 pearing about one mile from the point. The inner faces of these 

 higher dunes are covered with Uiiiola, among which Strophostylcs 

 lu'lvola, the beach bean, is so abundant as almost to hide the 

 sand. Among these two dominating species there is a good deal 

 of Cro/oii piDictatiis and Passijiora iucarnata. Behind the dunes 

 at this point there is along depression, in places slightly marshy, 

 which is covered with a dense mixed coppice of shrubs about ten 

 feet high. The most abundant species here is Myrica carolin- 

 cnsis, but with it are red bay {^Pcrsea Borbonid), cedar i^Jioiipcnis 

 virginiana), red mulberr}' {Moj-iis I'ubra) and live oak [Qucrcus 

 vii'giniaiia). In places Snii/ax Beyrichii and Anipclopsis arborea 

 {Cisstis bipiniiata) form a dense canopy over the shrubs. On the 

 bare ground beneath a good quantity of Agaricus canipcstris was 

 growing. On the edges of the coppice grew Callicarpa auuri- 

 cana, BaccJiaris halimifolia, Solaniiin nignnii, Monarda punctata, 

 Rubus trivialis and Ascyrum stans. 



The Fresh Marsh. — Returning to that part of the island further 

 to the east, represented in Fig. 3, we find behind the inner faces 

 of the dunes a low narrow marshy area in some places covered 

 with several inches of water, in others barely wet. The princi- 

 pal trees of this marshy strip are the old field pine {Finns Tavda), 

 the palmetto, and in places that are only damp, the li\'e oak. 

 The palmetto can grow in quite wet soil and is frequently seen in 

 standing water. Cormts stricta and Baccharis Jialiniifolia are the 

 principal marsh shrubs, but in places that are not too wet Myrica 

 caro/incnsis also occurs. The following \-incs are luxuriant here
