INTRODUCTION 
The Hempstead Plains, in the central part of Nassau County, 
Long Island, is a bit of prairie similar in aspect to parts of the 
Great Plains, and appearing quite out of place on the Atlantic 
seaboard. Its general geographical features were described by 
the writer a few years ago,* with a very superficial account of the 
* Bull. Am. Geog. Soc. 43: 351-360. f. 1-5. Мау, 1911. Reprinted in abridged 
form, with a different set of illustrations, in Torreya 12: 277-287. f. 1-7. Рес. 
1912. These contain references to some earlier publications which do not need to 
cited again here. See also New Internat. Encyc., ed. 2, її: 133. 1915.
