by Mrs. Florence Lydig Sturgis, is developing satisfactorily 
at the northeastern corner of the reservation. Some addi- 
tional species were added to the collection by trees brought 
from the nurseries. Some work was accomplished on the 
extension of the path system, which is as yet incomplete. 
5. Pinetum 
The collection of coniferous trees has not been much 
modified and but few additions have been made to it. 
Many of the trees planted in previous years have now 
developed into perfect and elegant specimens. The series 
of yews is especially noteworthy, and it is planned to 
extend this plantation somewhat in the spring. The 
severe weather of January killed three fine trees of the 
Deodar cedar (Cedrus Deodara), which had withstood 
winters for fifteen years and had attained a height of about 
18 feet; the Japanese cedars (Cryptomeria) were damaged 
by the frost, but have essentially recovered. 
6. Viticetum 
The vines and climbers on the arbor east of the economic 
garden were pruned in the spring, but the collection other- 
wise unchanged. It was found necessary to cut out a few 
contiguous trees which were shading some of the vines. 
7. Water Gardens 
No additional kinds of aquatics were added during the 
year. The hardy water lilies continued as a feature of 
beauty and interest throughout their flowering season. 
The large masses of cat-tails (Typha) which have developed 
here from very small beginnings, may now require some 
restriction of their progressive occupation of the borders 
of the pond. 
Both the hardy and the tender water lilies and their 
relatives, grown in the two concrete tanks in the court of 
conservatory range I, continued flowering freely. The 
leak in the tank containing the tender kinds, mentioned
