prove injurious to them.

destruction. They are so deeply fortified in 
the plants where they are situated, that nothing 
we can apply will reach them without destroying

old Strawberry plots, fresh broken up land, &c., 
and always avoiding plots that have had Carrots 
the year before. 
Grub. (See on Cauliflowers.) — The Larvee

the knife, and destroyed before the plants are 
earthed for blanching ; or the Mixture (No. 9) 
poured to the roots to send out the Grub, which 
must be immediately gathered by hand and des-

The larvae of the Fly, (I believe a species 
of 3Pisca,) commences its attacks on the leaves in

those Maggots which feed on the Cauliflower 
roots, and the Turnip. It feeds on the pulp or

leaving the two outer rinds or skins for its pro- 
tection or Jiarbour, where it remains till the fore
