A Native of the Landes on Stilts 



comparable only to those of Holland, 

 and which will afford miles of placid 

 water courses, avenues of traffic for the 

 products of the land, and a never-end- 

 ing source of enjoyment to pleasure 

 craft. 



In the case of the Everglades, the 

 exit of the water to the sea is prevented 

 by a limestone rim. In the case of the 

 Landes it was due to a bank of wind- 

 blown sand, which clogged all outlets 

 to the sea. The resemblance of the two 

 conditions is much closer than is at 

 first apparent, since this very rock rim 

 was once, no doubt, limestone sand 

 blown in by the wind and later hard- 

 ened into rock. I think geologists now

generally recognize that this rocky rim 

 is of eolian formation. The main dif- 

 ference between the two propositions 

 is that, in the case of the Landes, it was 

 silicious sand, which did not harden 

 into rock, but remained mobile, shifting 

 back and forth with every caprice of 

 the wind, while, in the case of the Ever- 

 glades rim. it was limestone sand, 

 which soon hardened into solid lime- 

 stone rock. As in sand dunes, the wind 

 laminations show in the rock like leaves 

 in a book, recording forever the charac- 

 ter of its formation. 



Before further describing the Ever- 

 glades, let me quote from my notes made 

 a few years ago, while visiting the
