 memoir volume, has been divided to appear in parts, the first of 

 which is now nearly ready for the printer. It is entitled "The 

 Vegetation of Montauk : A study in grassland and forest." 



The study of the forest area of Long Island, which has been 

 carried on for several years, has been continued. Dunns' the 

 growing season a " Big Tree " contest was started throughout the 

 Island and netted a large number of records. The results of this 

 were announced in the Garden Leaflets (Series X, No. 8, October 

 4), and the information collected is now being correlated with soil 

 and climatic factors from the different sites.

 the ecological survey of the vegetation of Mt. Desert Island. This 

 involves running a series of instruments there, as well as a similar 

 set in the pine barren portion of Long Island for comparison. One 

 more season's readings of these, both on Long Island and in Maine, 

 will complete this part of the work. 



I have continued the collection of Long Island and Mt. Desert 

 Island soils (in cooperation with the Bureau of Soils), and of
