The data obtained from the first determination, arranged in the 

 order of the moisture-content of the whole twig, are as follows: —

From these results it may be observed: (1) That there is a dif- 

 ference of practically 5 per cent in the moisture-content between the 

 extremes of the series. 



(3) That, while certain of the varieties furnish data almost iden- 

 tical, the increase in moisture-content is more or less continuous and 

 gradual throughout the series. 



(3) That the terminal portion of the twig (except in the case of 

 one or two varieties) contains more water than the basal portion, the 

 difference being, approximately, 2 per cent. 



Comparing the order of the varieties arranged according to 

 moisture-content, with that made by the Horticulturist, at the same 

 time keeping in mind Mr. Macoun's report of May 15th, it will be 

 seen that there is a. sufficient agreement between them to warrant 

 the conclusion, that there is a distinct relationship between moisture- 

 content and hardiness. Thus, the varieties Hebble White and Blen- 

 heim Pippin, placed by Mr. Macoun in the least hardy group (Group 

 IV.), are Nos. 8 and 10 respectively in the series according to per- 

 centage of moisture. Again, it is significant that the members of 

 Mr. Macoun's hardiest group (Group I.) are the three first on the 

 list according to water-content (i.e., contain least moisture), and that 

 their position is practically the same on both lists. It is true that
