perfect flowers are marked with a f. Glen Mary while classed 

 as a perfect variety has weak pollen and should be set with 

 perfect varieties in order to insure pollination. That is it should, 

 in our experience, be treated as though it bore imperfect flowers.

*Everbearing;. tPistillate varieties. 



Owing to the danger of early frost in this section it is 

 doubtful if the everbearing varieties can be depended upon for 

 more than the ordinary spring crop. During the season of 

 1917 no ripe fruit was produced by these plants later than 

 August 2. They were, however, heavily laden with immature 

 fruit when further progress toward maturity was stopped by 

 frost. 



Several of the native wild strawberry plants, so abundant 

 in Aroostook, were placed in the plot for breeding purposes. 

 While they responded to cultivation in so far as producing a 

 heavy growth of vine is concerned, the yield of fruit was ex- 

 tremely small and but little increase in the size of berries over 

 those produced under natural conditions was observed. 



The results from a single year's test are not conclusive but 

 it would be unwise to set for fruit in Aroostook County any 

 of the varieties like the Pearl, Chesapeake or Marshall that gave 

 small yields with a short fruiting season.
