PHENOLOGICAL OBSERVATIONS, CANADA, 1900.—MACKAY. 393 
3). 
REMARKS ON THE Nova SCOTIAN PHENOCHRONS. 
The Nova Seotian phenochrons are based on observations 
made in from ten to thirty observation stations in each county, 
on the 100 phenomena briefly indicated on pages 386 to 391 
—preceding “ Phenological Observations in Canada, 1900.” 
The observations, as a rule, are carried on by the pupils of 
the public schools, who are in competition with each other as to 
who will be the first observer of each phenomenon each year 
As these pupils often radiate as many as two miles from the 
school house each day, the observations “ when first seen” are 
likely to be as early as the most favorable spot in each school 
section will allow. The second date recorded—* when becom- 
ing common”—is more a matter of judgment; but must 
practically be as near the date “ wh2n first seen” in the most 
unfavorable spots of each school section as can be determined. 
The average differences between these two dates of flowering 
—“ when first seen” and “when becoming common ’”—in each 
county of the Province for the ten plants selected for our study 
are as follows:

Owing to the mild winter weather in Yarmouth, some plants 
about one week and four hours. 
flower very early in sunny spots; but the general flowering is 
so retarded as to be less in advance of the rest of the Province 
than the “first” flowering. On the average, it appears that 
flowering becomes common about one week after the first 
blossoms are seen,
