pedata, Corema, Hudsonia, Lupinus perennis, and Arenaria caro- 
finiana in the sand area, the display of orchids (Pogonia ophio- 
glossoides and Calopogon pulchellus) in the bog, and the rapid 
growth of well-established mats of creeping snowberry (Chiogenes 
hispidula), Linnaea borealis, and Epigaea repens. 
Through the cooperation of WPA labor, supplied by the De- 
partment of Parks, a rock wall and pathway were constructed at 
the north-western end of the Section. Likewise through this ¢o- 
operation two loads of broken serpentine rock were obtained from 
Staten Island. It is expected that the serpentine placed near the 
east entrance will be conducive to the growth of plants which have 
hitherto been unsuccessful in heavy garden soil. Several loads of 
peat were also obtained through the Park Department, adding 
greatly to the proper consistency of soil throughout the area. Our 
one great need is a limestone wall similar to the waterfall ledges 
in the Japanese Garden, upon which we can grow walking fern 
and other plants requiring shady calcareous habitats.
