injure the latter crops of Cauliflowers materially. 
Neither is the Cauliflower Brocoli or Cabbasre 
much infested by the former brood. The Cauli- 
flowers numerously infested as above often fall a 
complete sacrifice from their dissecting or con- 
suming the rind and pidp of the roots, and leav- 
ing no vessels or arteries for the conveyance of 
the sap for the supjiort of the plant. The plant 
soon exhibits a blue and drooping ajDpearance, 
which clearly indicates that those little miners 
are or have been labouring at its foundation, 
which often ends with the destruction of whole 
crops, even when they are nearly at perfection. 
Whether the Fly is attracted by some disease in the 
plant or no I am not decided, but it is common 
for the plants to be annoyed in some part of the 
gai-den, while in other parts they are not at all 
injured by them. 
Nothing has yet ever come under my notice 
that will destroy the Larvae but what would de- 
stroy the plant. The only plan I can devise to 
prevent their ravages will be to anoint the bottom 
parts of the lower leaves with the Mixture, 
(No. 12), using a Painter’s brush for the operation. 
This, together with frequent watering with the 
Mixture (No. 11) about the root, will, in a great 
measure, be a preventive to the parent Fly 
choosing it as a proper place for her progeny.

of the g’enus Noctua, includes this plant among 
the unbounded varieties which appear not to be
