ochorda grandifolia, Spirea crataegifolia, Spirea Van Houtii, Rhamuns al- 
pina and Lonicera albertii were frequently killed to the snow line. Abies 
concolor was severely injured down to the snow line but not killed back. 
The following specimens were lost entirely: Hydrangea Japonica, Vi- 
burnum tomentosa, Comptonia asplenifolia, Lonicera ledebouri and Judas 
tree: 
The following shrubs are of special interest from the fact that they have 
been newly introduced and have proven perfectly hardy: 
Japan Lilac (Syringa Japonica). Small trees about ten feet high and 
exceedingly vigorous, starting from their terminal buds and producing loose, - 
graceful clusters of cream-colored flowers, often fourteen inches long and 
nearly as wide, very conspicuous. Is a long time in coming into flower. 
Lonicera marrowii and L. standishii are much alike and seem perfectly 
hardy. They are bush honeysuckles of good habit and free flowering. 
Crataegus glandulosa, C. prinnatifida and C. microcarpa came through 
the winter in best condition and flowered abundantly. 
Ribes triste is a dwarf currant that seldom gets over two and one-half 
feet high, and has a pretty compact habit and bright glossy leaves that 
appear early and remain on until late in autumn. Its flowers are rather 
inconspicuous, and its fruit is of no value. As an ornamental plant for 
division lines between city lots and for similar purposes it promises to 
prove valuable. It was not injured in the least by the last winter. It grows 
easily from cuttings. 
By the severe weather of last winter many of the more tender varieties 
of plums were injured. Many of these varieties are new to us here, and 
we have never fruited them, so we cannot be sure that they are true to 
name. But in every case much care has been taken to obtain reliable stock, 
and it is fair to assume for the purposes of a preliminary report that they- 
are correctly named, especially where this data is supported by other evi- 
dence: Hungarian Prune, Communia and Yellow Aubert top-worked 
on Prunus Americana stocks about four feet from the ground were all of 
them very severely injured and killed back very much. They had made 
good large heads and had rather outgrown the stock. 
Col. Wilder, Sophia, Gold, Robinson, Wilson, Hilltop, Taige, Milton, 
Lombard, Charles Downing, Wayland and Prunus davidiana killed to the 
snow line. 
A few trees of a blue plum that were given to the Station by Mr. T. 
T. Lyon, who regarded it as hardy, practically killed out entirely. This 
variety had fruited for a number of years in Minneapolis and appeared ex- 
ceedingly promising. 
The Japan plum, known as Ogon, started from near the terminal buds, 
but made a very weak growth. I regard it as of no value for this section. 
Budd and Missouri apricots killed out entirely. Seedling cherries 
grown from seed imported from Riga, Russia, in 1891, that had made good, 
bushy trees, twelve feet high, killed out entirely.
