An illustrated folder announcing these different occasions was 
mailed to members of the Garden. 
Postcard Bulletins to Members. On April 26 a postcard bul- 
letin was sent to members announcing that a surplus supply of 
600 chrysanthemum cuttings was available for distribution. In 
May, another announcement was sent reminding members that 
seed and nursery catalogs were on file in the Garden Library for 
consultation. Attention was called to those catalogs dealing with 
rock garden plants, native plants of the eastern and western United 
States, and European alpines. 
Tree Study Calendar. he school year 1928-1929 being the 
year for tree study in the New York City schools, I prepared a 
list of common trees suitable for study in the schools, the different 
species being grouped month by month according to some prom- 
inent feature, connected, as far as possible, with the season of 
the year. This list was made at the request of Mr. Van Evrie 
Ree vice-president of the School Garden Association of 
w York, in charge of Nature-Garden work in New York City 
nee and through his organization these tree calendars were 
sent out to more than 12,000 teachers 
Collection of American Woods. During the past year a steel 
cabinet has been obtained for housing the collection of 38 different 
American woods received by the Garden several years ago from 
Pratt Institute. The collection consists of sections of tree trunks 
averaging about 8 inches in diameter, one half (lengthwise) of 
the upper portion of the trunk being removed in such a way that 
both one half of the cross section and the whole radial section 
are exposed. Each species has been neatly labelled with the 
botanical and scientific names according to the new check list of 
the United States (U.S.D.A. Miscellaneous Cir. 92, 1927), and 
the exposed wood surfaces have been given a moderate polish. 
They are now arranged on the shelves of the cabinet in systematic 
order, beginning with the conifers. 
Boy Scout Examinations. As usual, I have given occasional 
tests to Boy Scouts seeking to acquire merit badges in Conserva- 
tion and Forestry.
