The coast islands form a most interesting field for botanical 

 study, but unfortunately the spread of seaside resorts has cleared 

 one beach after another of its native flora until there is practically 

 no untouched forest except the tract back of Ventnor and south 

 of Atlantic City. This contains numbers of Pitch Pine Pinus 

 rigida, as well as Red Cedar Juniperus virginiana, White Oak 

 Quercus alba. Post Oak Q. stellata, Spanish Oak Q. triloba, 

 Shadbush Ainelanchier intermedia. Wild Cherry Prunus serotina, 

 Sumac Rhus copalina, Red Maple Acer ritbum, Grape Vitis cesti- 



* Dr. H. A. Pilsbry has found a precisely similar element in the Land 

 Snail fauna of the coast strip in the woods below Atlantic City. Cf. The 

 Nautilus, 191 1, pp. 34-35.
