396 PHENOLO6ICAL 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 al*o 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 in a 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 pbenochrons 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, inhere was not much difference
