AND CANADA, 1901.—MACKAY. 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.
