PHENOLOGICAL OBSERVATIONS, CANADA, 1900.—MACKAY. 395 
phenochrons ” given in the last two columns of the tables pre- 
ceding, show to the eye the general trend as well as several 
peculiarities of the time of flowering. 
The general trend is seen in the later flowering as the coun- 
ties lie north and east. There is a general conformity in this 
trend between the eight plants which fall into four groups, the 
Mayflower averaging 113.01 (24th April), the Dandelion and 
Strawberry 137 + (18th May), the Wild Cherry, Blueberry, 
Buttercup and Apple 154 + (4th June), and the Lilac 165 + 
(15th June). 
A general trend is also seen in passing from Guysboro in the 
east back to Cumberland in the west; although moving on the 
whole northward, the flowering becomes earlier. A similar 
change takes place in passing from Richmond to Cape Breton. 
This latter is more remarkable, for Cape Breton is not only north 
but also east of Richmond. This seems to suggest that the 
observers in Guysboro and particularly in Richmond, might not 
have been so keen in the search for the first flowering as those 
in Cumberland and Cape Breton ‘The small number of obser- 
vers in these counties also suggests such a possibility. But by 
reference to the table, it will be seen, that as a rule, in countics 
where the observation stations are so numerous that ten could 
be selected from the coast, ten from the low inlands, and ten 
from the high inlands, the earliest flowering is on the low inlands, 
then on the coast, and latest on the highlands. It must be 
remembered, that there is a very great difference in the altitudes 
of what are called the low and high inlands in the different 
counties. 
From such considerations, it is proposed in future to divide 
the Province into meteorological districts and sub-districts, 
instead of counties—the sub-districts being the coast belt, low 
inland belt and highland belt of each district; each district 
including a simple meteorological region or geographical slope. 
Among the peculiarities shown by these curves are, for 
instance, the lateness of the Strawberry as compared with the
