The SO-CALLED SAND-DUNES OF East Hampton, L. I. — In a letter re- 
ceived from Geo. R. Howells, of Soutli Hampton, of date January 21 , 
1886, my attention was called to certain sand ridges at East Hampton, 
L. I. The writer said: " Were you aware, I wonder, of the existence of 
two sand dunes, like small amphitheaters in form, right along, or in the 
midst of the richest farm lands a mile from the present shore line — per- 
haps not quite a mile — in the outskirts of East Hampton? These are 
veritable sand dunes of white sand covered with a growth of ordinary 
beach grass, and a geological puzzle. If we could say thej' were de- 
posited there by a cyclone, it would shorten matters, but we can't, and 
there is a difficulty in holding tliat they are signs of an old beacli line. 
It is with me a standing puzzle."
