dable of the enemies of the superior and cultivated 
vegetable species. 
The mildew, which has often occasioned great 
havoc in our wheat crops, and which was par- 
ticularly destructive in 1804, is a species of fungus, 
so small as to require glasses to render its form 
distinct, and rapidly propagated by its seeds. 
This has been shown by various botanists ; and 
the subject has received a full illustration from the 
researches of the late ever to be lamented Sir 
Joseph Banks. 
The fungus rapidly spreads from stalk to stalk, 
fixes itself in the cells connected with the common 
tubes, and carries away and consumes that nourish- 
ment which should have been appropriated to the 
grain. 
Various remedies have been proposed for this 
disease. The Rev* Dr. Cartwright states, that he 
has successfully treated it, by the application of a 
solution of salt, by a common gardening pot, to 
the stalks of the corn. This is a subject worthy of 
the most minute investigation ; and all methods 
should be tried which promise to eradicate so great 
an evil. As the fungus increases by the diffusion 
of its seeds, great care should be taken that no 
mildewed straw is carried in the manure used for 
corn , and in the early crop, if mildew is observed 
upon any of the stalks of corn, they should be 
carefully removed, and treated as weeds. 
The popular notion amongst farmers, that a bar- 
berry-tree in the neighbourhood of a field of wheat 
often produces the mildew, deserves examination.
