by Mr. Nash in the Journal for March and July. The 
autumn was very fine, and the dahlias were not killed until 
November sixth. 
Supervision of the work on the control of destructive 
insects has been continued by Dr. Seaver. It was thought 
that the unusually severe winter might affect the viability 
of the tussock moth, but experiments showed this hope to 
have been unfounded. Large numbers of the egg-masses 
were gathered in the spring and destroyed. The destruc- 
tive work of the tussock moth was not excessive on our 
grounds, due in part at least to artificial control. 
The Japanese cherries have suffered considerable damage 
from the West Indian peach scale (Aulacaspis pentagona). 
Special attention is being given to this insect with the 
hope of clearing out the pest. Aphids were exceedingly 
numerous during the season but their natural enemy, the 
lady-bird, was also very abundant and helped to reduce 
the destructive work of these insects. The rose beetle 
and other standard pests continued their work and have 
been combatted as formerly. Work on the control of rose 
mildew and other destructive fungi has also been continued 
as usual.
