When many calendars of this kind fhall be 
made in different places and nations in the fame 
year, it will be ealy to colled from the blowing 
of thefe forts of flowers, and from the leafing 
of trees, how one climate differs from another, 
and why plants brought from the Southern parts 
feldom produce fruit with us, whereas the Nor- 
thern plants fucceed very well. Thus at Mont- 
pelier the fpring is forwarder than at Upfal by 
31 days, at London by 28* at Falconia by 6 ; 
and the winter comes on as much later in thofe 
places. 
Botanifts and apothecaries, whofe bufinefs it 
is to gather plants juft when they are in blow, 
may by this means learn at what time that may 
be done, and need not feek in vain at an im- 
proper feafon, and may farther know by their 
garden plants, what wild ones are to be found 
in the fields precifely at the fame time and on 
the contrary. 
The night frofts which fo often deftroy our 
plants, and which i imagine come to us from 
Lapland, may be known in the fame way. 
Thus the LEAD cold arifing from the thaws 
happens at the end of the leafing 
in Lapmarck, 
feafon.
