A Receipt for Preventing the Flies from Damaging the Seedling Leaves of Turnips, Cabbages, and Many Other Vegetables, for less than 6d an acre charge

A RECEIPT for preventing the flies from damaging the seed-
   ling leaves of turnips, cabbages, and many other vegetables,
   for less than 6d an acre charge.
MIX one ounce of flour of brimstone with three
pounds of turnip-seed daily, for three days succes-
sively, in an earthen glazed pot, and keep it covered
close, stirring together well at each fresh addition, that
the seed may be the more impregnated with the sulphur;
then sow it as usual on an acre of ground ; and let the
weather happen wet or dry, it will keep the fly off till
the third or fourth seedling leaf is formed ; and by this
time they will be somewhat bitterish, and consequently
much out of danger of this little black flying insect,
which in summer may be seen sometimes in swarms on
the wing near the ground, searching for and settling on 
the fresh bites, till they ruin thousands of acres in some
seasons, by lying and residing under the little clots of
of earth at night, and during the day following.
