planting program has been carried out. Within the next decade 
we should have small stands of red maple, beech, white pine and

1 pine ina flourishing condition, each group accompanied by 
Iextension of the boundary fence northward to the pathway 
coming from Ilatbush Ave. has made the section seem more 
natural and has considerably increased the area. The soil of 
much of this newly acquired addition has been improved by turn- 
Ing in peat. 
The brook, made in the fall of 1932, has become a natural fea- 
ture of the landscape and provides moisture for the growth of 
ferns, Virginia cowshp (Afertensta) and many species of violets. 
In the sand area there has been gratifying success in the growth 
of two species of FHudsonia, Corema, Tephrosia, Arenarta caro- 
liniana, Huphorbia Tpecacuanhae, native species of Helianthemaim, 
etc. together with mass plantations of l’iola pedata. It has been 
interesting to observe the variations of flowering-time in the native 
species of blue-eyed grass (Sisyrinchiin angustifolium, S. at- 
lanticum, S. arenicola and S. mucronatum), and it is expected that 
the opportunity for similar close observations will give us much 
information on the relationship of native species within puzzling 
genera. 
The bog has completed its third year and the plants show no 
sien of losing vitality. Pine-barren plants such as curly-grass 
(Schisaca pusilla), pipeworts (frtocaulon compressum and dec- 
angulare), Lophiola, Lachnanthes, Nyris, Drosera filiforiis, 
Helonias bullata, Sabatia lanceolata, and several species of orchids 
are thriving in the wet peat which they share with northern repre- 
sentatives, Calla palustris, cottongrass (Eriophorum spissum), 
Kalmia polifolia, rhodora (Rhododendron canadense), and species 
of Carer. In the adjoining peat-and-sand area Pyvidanthera and 
turkey beard (Nerophylliuim) are growing luxuriantly. The moist 
bank adjacent to the bog has for two years supported a good 
growth of bunchberry (Cornus canadensis), creeping snowberry 
(Chiogenes), Linnaea borealis var. americana, and Dalibarda re- 
pens, plants confined to mountain regions of our area. 
Practically all the desirable plants native within 100 miles of
