EFFECTS OF THE WINTER OF 1919-1920 ON THE 
WOODY PLANTS IN THE GARDEN 
While the winter of two years ago had several days when the 
temperature was lower than ever before recorded here, the past 
winter was more continuously cold than any other for thirty 
years. The notes on the effects of the past winter are, therefore, 
a record not so much of what one unprecedented period of low 
temperature will do, but rather the cumulative effect of two ex- 
ceptionally bad winters, with only a single mild one intervening— 
that of 1918-1919. 
Taking first of all those killed outright, the following woody 
species have been lost to our collections: 
WINTER KILLED 
Picea obovata, P. sitchensis (except snow protected speci- 
mens), P. Alcockiana, P. orientalis, P. morinda; Abies cilicica,
