Mr. Moore and myself began during the summer a compre- 

 hensive ecological and phytogeographic survey of Mt, Desert 

 Island in Maine. On this island there is a tension zone, in a 

 small area, of such widely diverse forest and phytogeographic 



I 



types as the pitch pine, fir, spruce, Quercus ilicifolia, Empetrum 

 nigrum^ and many others. Here on one island, at sea level are 



r 



to be found arctic-alpine and southern coastal plain vegetation 

 types, and the opportunity to study the limiting factors is un- 

 rivalled. It is planned to continue the study over a period of 

 years and ultimately write a report upon 

 forest types of the island. A preliminary paper on '' Plant Com- 

 position and Soil Acidity of a Maine Bog" was read before the 

 Ecological Society of America at the Chicago meetings and will 

 appear in a future issue of Ecology. ' ^ 



. During the past year I completed a study of the endemic flora 

 of the Bahama Islands begun five years ago. With the consent 

 of and with many helpful suggestions from Dr. N. L, Britton 

 who, with Dr. Millspaugh of the Field Museum in Chicago, is 

 the author of the recently issued '* Bahama Flora," my studies 

 were based upon this book, and a paper on '' Endemism in the 

 Bahama Flora" was prepared and read before the Botanical So- 

 ciety of America at the Chicago meetings. 



After repeated failures I was at last able to spend three days 

 on Gardiner's Island where in the " Great Woods " is the finest 



■ 



climax forest anywhere near New York. I hope to spend a 

 few more days there in the spring of 1921. The notes and photo- 

 graphs collected will be of the greatest use in the ''Vegetation of 

 Long Island" upon which I have been working for several years. 

 Several series of atmometer records were made at Montauk, the 

 barrier beach at Fire Island, and in the pitch-pine forest in the 

 center of the Island. During the coming season weekly readings 

 will be taken from certain of these places and one from the sand 

 plains near New Haven, Conn., partly in cooperation with the 

 Department of Botany at Yale. These records of the evaporat- 

 ing power of the air, in practically identical sites, but differing 

 in their proximity to the sea-breeze appear to indicate significant
