XIIL PHENOLOGICAL OBSERVATIONS, CANADA, 1890, BY A. H. 

 MACKAY, LL. D. 



(Read 9th April, 1!)00.) 



The schedule on which the observations referred to here 

 were recorded specifies 100 different objects, some with sub- 

 divisions. Of the great majority of them, two classes of 

 observations are asked to be recorded : " When h'rst seen," and 

 " When becoming common." In the tabulated dates recorded 

 by the Botanical Club of Canada, given at the end of this, 

 paper, the first series only is taken. The character of the 

 schedule is also indicated in these tables of observations at the 

 thirteen stations throughout Canada. 



The identical schedule is also used in the public schools 

 of the Province of Nova Scotia. The observations here are 

 made by the pupils in attendance as a part of their " nature 

 study," when going to and returning from school, and are 

 tested and recorded by the teacher in duplicate, one copy of 

 which is preserved as a local record, and the other is sent with 

 the school returns to the Inspector for the Education Office. 



Seven hundred and twenty-five school sections (school 

 districts, localities, or stations) returned schedules of observa- 

 tions, the majority more full than those of the thirteen stations 

 of the Botanical Club reporting. The summation of these in 

 tabular form would require a large volume, and cannot, there- 

 fore, be attempted here. The schedules are bound up in a 

 volume for each year, so that the information may not only be 

 preserved for the future use of students, but may be conveniently 

 accessible. The series of volumes will be a mine of information 

 bearing on at least one phase ot the problem of secular variation 

 of climate. 



The same ten plants taken last year are here selected from 

 the list of one hundred objects for the purpose of comparison
