Through exchange with the American Museum of Natural 
History, the Garden has recently acquired twenty-eight speci- 
mens of matrix containing some twenty species of fossil plants, 
representing a part of the collection made in 1891 and 1892 on 
the south shore of Nugsuak peninsula, Greenland, by the Arctic 
Expedition of the Philadelphia Academy of Sciences, under 
command of Robert E. Peary, C.E. (now Rear Admiral), U.S.N. 
These are the only fossil plants from Greenland in the Garden 
collections and they constitute a very valuable and interesting 
addition to the Cretaceous and Tertiary floras. They apparently 
belong to the Upper Cretaceous (Patoot) and Eocene-Tertiary 
(Upper Atané) beds, described by Oswald Heer in his ‘Flora 
Fossilis Arctica,’ volumes 1, 2, 3, 6, and 7

The oldest Japanese chestnut tree on the grounds, one that 
has survived since the early days of the Garden, persisting through 
the terrible epidemic of canker which killed off all the other 
chestnuts, failed to put forth its leaves this spring. It is dead— 
killed by an attack of the canker that was almost imperceptible 
at first, but finally proved too strong for it. This tree has beea 
carefully observed for fourteen years, or since the canker was 
discovered in this vicinity. The disease gained entrance several 
years ago through a small branch three feet above the ground
