THE GEOLOGY OF LONG ISLAND, ETC. 



Silicofiagellates and Diatoms may be expected in the forth- 

 coming report of the Biological Survey of Long Island Sound 

 conducted by Dr. P.S.Galtsoff under the direction of the U. S. 

 Bureau of Fisheries. Material in the possession of Professor 

 Transeau will undoubtedly yield new records for the Con- 

 jugatae and Chlorophyceae. Many exotic species of ferns 

 and seed plants are represented in the gardens of estates in 

 the vicinity of Cold Spring Harbor. The estates have gen- 

 erally been available to members of the Laboratory, and 

 their flora will be the subject of a later list by the writer. 

 Botanists will be able to collect abundant material for class 

 room use in the vicinity of the Laboratory, while the range 

 of the flora may prove suggestive to the plant anatomist. Of 

 especial interest to the latter are the -fossil plants of long 

 Island, the structure of some species of which have been 

 studied by Hollick and Jeffrey ('09) but many have not 

 received such attention. 



The account given of the relation of the geology of Long 

 Island to the flora, so far as it has been studied, may be of 

 interest to the plant ecologist. As suggested by Conard 

 ('24) it is hoped that .observers may be found to study the 

 succession of the vegetation in subsequent years in the salt 

 marsh and sandspit. Investigations of the salinity of the 

 water in the various creeks and rivers flowing into Cold 

 Spring Harbor, and the rate of evaporation at different lev- 

 els above and below high water marks await plant physi- 

 ologists, to whom the flora of the salt marshes, especially 

 those plants which are exposed to both fresh and salt water 

 are of peculiar interest. Opportunities for the plant geneti- 

 cist are at present mostly limited to collaboration with mem- 

 bers of' the staff of the Carnegie Institution. 



The adjacent library of the Department of Genetics, Car- 

 negie Institution of Washington, the easy accessibility of 

 the New York Botanical Garden, the Brooklyn Botanic Gar- 

 den, the American Museum of Natural History in New York 

 City, and the Boyce Thompson Institute for Plant Research 

 at Yonkers, N. Y., in addition to the above make the Bio- 

 logical Laboratory at Cold Spring. Harbor, N. Y., a con- 

 venient center for botanical research the year around within 

 of course the limits of the type of investigation to be pro-
