VI.—PHENOLOGICAL OBSERVATIONS, CANADA, 1898, COMPILED 
By A. H. MacKay, LL.D., Halifax, from Observations 
of the Botunical Club of Canada, and of over seven 
hundred of the Public Schools of Nova Scotia. 
(Read April 17th, 1899.) 
In order to continue the publication of the series of the 
observations of the Botanical Club of Canada, | give hereafter a 
table of the observations made by the thirteen members 
making a phenological report for 1898. I can but give a sum- 
mary of selections from seven hundred reports from as many 
localities in the Province of Nova Scotia. That these observa- 
tions are of very great value in measuring the phenological 
conditions of the various portions of the province can be readily 
inferred from the facts, that each report comes from a school in 
which numbers of pupils were observing on their way to and 
from school under the direction and stimulation of the teacher, 
and is therefore likely to be in most cases more accurate than 
one made by a single observer; that the reports represent 
every part of the province; and that they represent more or less 
numerous localities in each county of the province. 
For the compilation of the tables which immediately follow, 
ten of the most complete schedules or reports from each county 
were selected (except in the cases of the counties of Qucens, 
Antigonish and Guysboro, where the full schedules were not 
sufficiently numerous, and were respectively five, five and six). 
From these were selected the same TEN plants which had the 
time of “first flowering” and the time when “flowering was 
becoming common” both recorded. From these averages or 
mean dates of flowering have been found, which we may 
speak of as “phenochrons,” the times of the appearances of 
the phenomena observed expressed in the terms of the days of 
the year. For such computations it is necessary to have some
