This report illustrated by distributional maps, graphs and pho- 

 tographs almost whoUy deals with a study instrumental and other- 

 wise of the salt raarsh Vegetation of the inner harbor at the Marine 

 Biological Laboratory at Cold Spring Harbor, Long Island, New 

 York. The different species of plants, such as the algae and flo- 

 wering plants are enumerated and are referred to the different tide 

 levels of the harbor and marsh, determined by instrumentation. 

 The different plant associations and their distribution are referred 

 to the lide-level at which they usually occur. Thus, whe have the 

 bottoni Vegetation of the harbor from 0,5 to 1,5 feet including the 

 sub Httoral and lower littoral belts and comprising the Enhalid 

 formation of Warming and the lithophilous Benthos. The mid lit- 

 toral Belt comprise that part of the harbor and marsh at 1,5 to 6,5 

 feet. Here we find the salt seed grass, Spartina glabra var. alterni- 

 flova, and other associated species together with the rockweed asso- 

 ciation on wharfes and jetties. The Upper Littoral Belt is found 

 from 6,5 to 8 feet and includes the associations of Spartina pafens, 

 Suaeda maritima, Salicornia europaea, Juncus Gerardi and other 

 plants, including algae. The supra littoral beach , or storm beach 

 of the east and west sides of the harbor, occurs from 8 to 10 feet 

 and includes many plants which are controlled b}' fresh water.
