creeper abounds and Smilax rotundifolia L, As the sand blows 

 in about the trees, these lianes are covered up with the trees until 

 the tops of the trees only are exposed. The lianes then take root 

 and spread out in all directions circurnferentially a distance of 

 many feet from the tree which, now dead, formerly supported 

 them. The lianes, therefore, began their life-history on the lower 

 level ground and conclude their growth on the surface of the sand 

 dune fifty feet above where they first took root — veritable vegetal 

 Jacks-and-the-Bean Stalk. This curious biologic feature, never 

 before mentioned, to the knowledge of the writer, in conned ion with 

 the life-history of a sand dune, is exemplified on all of the higher 

 sand hills at Piermont.
