PHENOLOGICAL OBSERVATIONS, CANADA, 1898. MACKAY. 99 



From the general phenochrons we infer that the Spring of 

 1898 in the Province of Nova Scotia, was according to the 

 Botanical Club, 3.7 days earlier than the average of the seven 

 years preceding, and according to the Schools only 1.3 days 

 earlier. But what is the cause of this difference of 2.4 days 

 difference between the Club and the Schools ? Not defective 

 observations, but the fact that of the eight stations of the 

 Botanical Club, nearly all were either southern or central, 

 while those of the Schools were evenly distributed from Cape 

 Sable to Cape North. 



Average flowering dates of five plants selected from the 

 preceding tables, (a) for the first nine counties of the Province
