and growth. It is proposed to start a set of experiments on this 
during the coming summer, as the information thus gleaned is 
needed for a right understanding of the germination and growth 
of Long Island forest trees, as well as the associated vegetation. 
During the growing season atmometer records and soil tem- 
perature records were secured weekly from a Pitch Pine station 
near Coram, in harmony with synchronous records being taken 
in connection with my work with Major Barrington Moore on 
the vegetation of Mt. Desert Island, and with similar records 
taken by the New York Botanical Garden, the Yale Forest 
School, and the Forest School of Syracuse University. 
The work of the Nassau County Mosquito Extermination 
Commission in ditching the salt marshes has so changed some 
of them, and the changes have such far-reaching practical possi- 
bilities, that a study of the vegetation of these, and the peat and 
muck underlying them was carried on. Such factors of the en- 
vironment as the changes in temperature, specific gravity, and 
hydrogen-ion concentration of the water of the marshes at the 
surface and at different depths, was studied in considerable detail. 
The changes of tide levels, both daily, monthly, and as between 
summer and autumn, affect the marshes so profoundly that | 
felt obliged to carry on this work late into the fall, and at my 
own expense, after Garden appropriations for field work were 
exhausted. There is still a good deal of work in connection with 
these marshes to be done, particularly during the very high tides 
that come at the Spring Equinox. 
The field work on Mt. Desert Island vegetation is now com- 
pleted, and the results of this study, extending over four sum- 
mers, are in preparation for volume three of the Memoirs of the 
Garden. The study has been made possible by Garden appropri- 
ations and by the very pleasant hospitality of my friend and 
colleague in the work, Major Barrington Moore.
