396 PHENOLOGICAL OBSERVATIONS, CANADA, 1900.—MACKAY. 
Dandelion in Shelburne, Queens and Guysboro; and its advanced 
appearance in Kings, Cumberland, Inverness and Victoria. 
Does the breath of the Atlantic retard the flowering of the 
Strawberry as compared with the Dandelion ? 
It also appears that the southern and sea surrounded Yar- 
mouth is favorable to the early flowering of the Mayflower, but 
comparatively not so favorable to the Lilac. The manner in 
which the other curves intersect each other have also their 
explanations. But we are not yet ina position to be able to 
state them. 
The stations of observations are, necessarily, not the same in 
each county each year. It is therefore possible that the pheno- 
chrons might be affected by a change in the relative number of 
coastal, inland and highland stations. 
As all these observations are bound carefully into a large 
volume for each year, anyone having the time can use the facts. 
recorded in any combination promising the most useful results. 
The present selection of ten plants, and the comparison of their 
flowering phenochrons in each county is merely a sort of pre- 
liminary or provisional testing of the possibilities and probable 
value of such observations—sufficient to interest the observers 
while they are developing accuracy—and a record of facts for 
future generalization. . 
In the second plate (page 397) there is a comparison of the 
“mean” flowering phenochrons of the Mayflower, Strawberry, 
Apple and Lilac, for the years 1898, 1899 and 1900. 
It indicates that the Spring of 1898 gave early promise, 
while those of 1899 and 1900 were later as measured by the 
Mayflower. The averages of these two years over the whole 
Province are nearly the same, the differences in the different 
counties being explicable as due to prevalent winds and degrees. 
of sunshine. 
As measured by the Strawberry, the first half of May 1900, 
was nearly a week more backward than in 1898 and 1899. 
As measured by the Lilac, there was not much difference
