spurs of the Japanese varieties were killed in about the same 

 degree as those of the domesticas. Georgeson and Abundance, 

 however, were somewhat injured on the top growths, but the 

 trees do not appear to have been damaged. Burbank, Red June, 

 and Yosebe (of our Bulletin 106, Fig, 13), were wholly uninjured, 

 save the loss of the fruit-spurs. Yosebe even bore a few flowers, 

 but they did not set fruit. Judging from the behavior of the 

 Japanese plums upon our grounds last winter, they are about as 

 hardy in tree and bud as the common run of the domesticas. 



In contrast to the domestica and the Japanese varieties, the 

 Americana types stood the winter without a blemish and are now 

 carrying a full setting of fruit. Even one or two of the Chicasaws 

 blossomed, but they will probably mature no fruit. Wild Goose 

 was not injured. 



Apricots. — The winter totally destroyed the entire fruit-spurs 

 of all the apricots upon the Cornell plantation, including the 

 Russian varieties (Budd, Gibb, Catherine, Nicholas), and the Rus- 

 sian almond of Lovett (which is an apricot). The only variety 

 which was seriously killed back in limb is the Royal, but the 

 wood of nearly all apricots is discolored. Early Golden and 

 Moorpark did not kill back; and young trees of the Primus Mume 

 type (see Bulletin 71) were only slightly injured. The Russian 

 varieties were least injured in wood of any of our apricots. When 

 pruning the trees this spring, it was very noticeable that the wood 

 of the Russians was hard and firm and comparatively little dis- 

 colored. Yet, I should not advise the growing of Russian apricots 

 in this region, because other kinds bear so much better fruit, and 

 it is only at long intervals that we have such winters as the last 

 one proved to be. 



Dwarf Cherries. — We have three types of dwarf cherries 

 (see Bulletin 70) growing together in a border alongside a lawn. 

 One of these is the common sand cherry (Ptmnus ptunila) of the 

 east. This was uninjured. Another is the western dwarf cherry 

 {Prunus Besscyi). The form of this known as the the Improved 

 Rocky Mountain dwarf cherry was very severely injured, and one 

 bush of it was killed back to within six or eight inches of the
