hardly been grown in our garden. It is now hoped to remedy this 
with the construction now nearing completion, of a shady and

moist, north-facing “ravine” on the South shore of the Lake, 
where it is hoped we may succeed in growing Sphagnum, Mosses, 
Liverworts, certain Algae, and ferns that require such a habitat. 
LABELS 
Our system of labeling, like some other methods, was inherited. 
Many years ago wire supports were discarded in favor of metal 
rods. At various times, including the past vear, we have had 
trouble with the lead-antimony plates being removed. Wooden 
— 
abels suspended from branches are used extensively in other gar- 
dens. We have now put out about five hundred such. For tall 
shrubs and low trees, for example, Prunus, these labels have proved 
very satisfactory. The cost 1s hardly one-tenth of that of plate 
labels. 
EXHIBIT 
An exhibit of “ Flower Structures and the Classification of 
Dicotyledons,” comprising drawings by Miss Maud H. Purdy and 
diagrams prepared by Mr. Louis Buhle, was made in connection 
with the A. A. A. S. meeting at Atlantic City, December 27-31. 
CLASSES 
Outdoor instruction in the garden during spring and fall has 
interested me for many years. lor two years Mr. Doney has 
taken over the course on Ornamental Shrubs, giving attention not 
only to characteristics especially at the time of flowering, but also 
to horticultural requirements. 
Two new courses were given by me, one during May on lilacs 
and one during October on evergreens, including conifers and 
broadleaved evergreens. 
SEED EXCHANGE 
The total number of seed packets distributed was 5137, the num- 
ber requested was 5426. Of these, 683 packets were sent to 
members of the Brooklyn Botanic Garden and 4454 to our regular 
botanic garden exchanges—mostly in foreign countries.
