tree, more fuited to this purpofe ; and which 
fome provinces might ufe as a calendar* white 
the greateft part might confult the birch . It is 
a popular error, that lefs time pafTes between 
the lowing, and ripening of wheat in our nor- 
thern provinces, than here at Upfal, and that 
this happens becaufe the fummer days are longer 
in the north, and there is fcarcely any night to 
retard its growth. But this error is made evi- 
dent by the grain ripening in as Ihort a time in 
Schonen as in Lapland. For barley in the cham- 
pain part of Schonen is fown about May the 
29th, and reaped fooner than in Upland. But 
why barley ripens later in Upland and Weir- 
mania, than in the other provinces of Sweden, 
is to me abfolutely a fecret,

If a number of future obfervations lhall con- 
firm the do&rine, which i have been delivering, 
i do not doubt but that we may reap many ad- 
vantages from it. For then we fhpuld not want 
a fure guide for the hufbandman to regulate 
himfelf by in fowing his grain, and for the 
gardener to fow his kitchen, and other feeds. 
What great benefit therefore would arife to the 
public,
