NEW VINE SCOURGE. 303 
Once only, two years ago, the Prefecture desired the 
Professor of Agriculture to work it out, and report 
upon it. 
Amongst us the causes of the disease would be very 
difficult to verify. Most particular attention should be 
paid to all the conditions of any locality in which it 
may happen to be dying out. 
The means adopted to combat it offer nothing new, 1 
nothing local. The practice in this regard is the same 
as in the district of Gard, &c. — in all cases eradication 
of the infected vines. 
Many other questions besides those answered above 
might have been put ; e.g.,— -Is the insect called Phyl- 
loxera vastatrix the cause, or only the consequence of 
the disease ? 
Again, do the cases which have occurred among us 
bear evidence of being the same malady as that which 
has been so general, so destructive, in Languedoc ? 
These points, the importance of which any one 
can see, are at present very far from having been 
cleared up. 
Quite recently there has appeared a sort of resume, 
with drawings of the insect, by M. Heuze. 
Such, Sir, is the information which it is in my power 
to transmit. I hope you will find it sufficient. At 
any time I shall be happy to render any assistance in 
my power. 
I have, &c, 
(Signed) Corti.
