AND CANADA, 1901. MACK AY. 491 



Remarks. 



" The Compiler filling one of these blanks should keep one 

 copy for himself while sending the other to the compiler-in- 

 chief." 



" The set of stations on the right, under " when becoming 

 common," must be exactly the same as on the left, under " when 

 first seen." 



A plate of graphs showing the relation between the flower- 

 ing phenochrons in each region of the province of Nova Scotia, 

 for the dates " when first seen " and " when becoming common " 

 is given on page 496. " When becoming common " must always 

 be a matter of personal judgment ; so that the general conform- 

 ity of the five pairs of curves for the flowering of the Mayflower, 

 Strawberry, Apple, Lilac, and Blackberry, on the said plate is 

 very interesting.
