brought along to potting size by early summer of 1926 and, ac- 
cording to plans earlier announced, distribution was made of 
these young plants for the purpose of naturalization. Plants 
were sent to sixteen different people distributed in eight different 
states, with a distinct understanding that the ferns were to be 
set out under conditions as nearly like their natural habitat as 
possible, and those to whom the plants were sent were asked to 
keep close watch of them, so as to report the success of this broad 
demonstration experiment. A considerable number of the plants, 
which were too small during the summer of 1926, still remain and 
will be offered for distribution again in 1927, under the same con- 
ditions as last year. 
“In connection with the Hart’s Tongue, an effort was made to 
secure a good series of photographs of the so-called East Green 
Lake, near Jamesville, New York, at which some of the best 
groups of native Hart’s Tongue Ferns are located. Activity by 
the Solvay Process Company has already destroyed the habitats 
of several colonies of this fern, and the quarrying operations have 
disfigured what was formerly a very beautiful spot. I was 
fortunately able to secure from Mr. !’arle Wilson, of Syracuse, 
and Mr. H. E. Ransier, of Manlius, New York, a series of pic- 
tures showing conditions before and since the industrial opera- 
tions were begun. Copies of these photographs and lantern slides 
from some of them have been added to the Garden collections.” 
Botanical and Horticultural Congresses 
International Congress on Flower and Fruit Sterility 
The conference was held August 12-14, under the auspices and 
with the financial support of the Horticultural Society of New 
York. The first day’s sessions were held at Columbia University 
(in the morning) and at the New York Botanical Garden (in the 
afternoon) ; the second at the Boyce Thompson Institute for 
Plant Research; and the third at the Brooklyn Botanic Garden. 
At the latter session eleven scientific papers were presented in the 
morning and fifteen in the afternoon. Over one hundred dele- 
gates were present from about 38 institutions and organizations, 
and representing about 12 foreign countries. The delegates were
