As was anticipated, the removal, during grading operations, 
of a portion of the terminal glacial moraine just north of the out- 
let of the lake, disclosed a large quantity of erratic boulders. 
These have all been placed in a pile just west of the present 
ecological section, at the base of the Flatbush Avenue border 
mound, and will be utilized later in the construction of a 
rockery, which will form a division of the ecological section. 
During July the bog in the wild flower section was en- 
larged by about one-third, and the new portion planted to in- 
sectivorous plants, to which it will be exclusively devoted. The 
group at present includes Drosera rotundifolia, D. intermedia, 
and D. filiformis, Dionaea muscipula, Sarracenia purpurea, S. 
flava, S. Drummondii, S. rubra, S. variolus, and species of 
Utricularia. The relatively large flowers of the Dionaea 
(Venus’s fly-trap), and the graceful, yellow flowers of Utri- 
cularia (bladderwort), and also the profuse blossoms of the 
sun-dews (Drosera) have been objects of much interest during 
the past summer. The new part of the bog has been covered 
with a carpet of live sphagnum. 
During the first week in August the labeling of the ecolog- 
ical section was practically completed, so far as planted. 
On July 11, the Garden received from Prof. George F. 
Atkinson, of Cornell University, a number of plants of the 
water fern, Marsilia quadrifolia, collected by Mr. M. Ishikawa. 
This fern, named from Aloysius Marsili, an early Italian 
naturalist, is a native of Europe, and appears to have been 
first introduced into this country in Bantam Lake, Litchfield, 
Conn. This has been the center of its distribution in America. 
About 28 years ago, at the request of Prof. William R. Dudley, 
then professor of botany in Cornell University, Mr. Irving 
Hamant, a medical student in Cornell from 1884 to 1886, brought 
specimens of the plant from Bantam Lake. Some of these were 
planted by Prof. Dudley in Eddy Pond, directly beyond the 
“Cascadilla Woods,” east of the Cornell campus. Specimens 
were also planted in two different places near the mouth of
