The Heesian fly lays It's eggs N the

Prot Webster Gays that all writer's
both chronological, and agricultural
agree in recomending a. a remedy for .
and q preventive Of the ravageq Of this F..
insect, that at least part Of the Whea
should not 1e gOwn until after the 10Th /.

Fitch. Harris and Cook concur in recon- I
mending 5his course in districts infested .
by these pests even though the wheat +.
may be in danger Of injury from the
cold auUmlaI or winter weather. we .
may therefore conclude, that on the
whole says Prot Webster, 'late SOW,
ing is the best general remedy; but still
part Of the wheat should be sown
early a. 4 decoy % draw of the flies
and induce them IN lay their egrs N
the early sown grain, that the later
sown portion may escape their attacks,
and then farmers should plOw under
and re-sow the fields Of early grain. -
