MIDSUMMER REPORTS. 



CENTRAL TRIAL STATION, ST. ANTHONY PARK. 



SAMUEL B. GREEN, SUPT. 



While the past winter, as regards temperature, was rather mild, 

 yet there was more damage from winter injury to herbaceous plants 

 than for a number of years and less injury to many woody kinds. 

 For instance, an ornamental shrub which we know as Rhamnus 

 Alpinum, which has usually killed to the snow line and often to 

 the ground, this spring started from its terminal bud. On the 

 other hand, strawberry plants were considerably injured, even 

 when protected by heavy mulch. I think this injury to herba- 

 ceous plants largely due tb the forming of a crust of ice on the 

 surface of the ground, which remained for some time. 



Our apple trees are in good condition, and the Duchess and 

 a few other kinds promise heavy crops, though the crops on most 

 of the varieties will be light. Some varieties of plums will produce 

 heavy crops, while the Surprise seems to be somewhat injured, and 

 it's crop is very light. 



I have received two samples of the growth of the Surprise 

 plum which are swollen up and distorted. I think this is plainly 

 due to the effects of the fungus that commonly causes plum pock- 

 ets (Exoascus deformans), but in this case it has attacked the new 

 growth as in the peach, where it forms similar swellings, that are 

 known as peach leaf curl. 



Our strawberry beds afford a good illustration of the relative 



hardiness of varieties. The following table showing the condition 



of strawberries at the Central Experiment Station in spring of 



1906 gives some idea of these results :
