pointed by the Government to study the subject. 
Mr. Consul Crawfurd in his report, dated 29th June 
(No. 56), was probably correct in his opinion as to the 
exaggeration of the statements current at that time. 
No harm can, however, arise from the vine cultivators 
being thoroughly warned beforehand as to the serious 
nature of the malady. There is reason to believe that,

prompt destruction of the vine, its burning on the 
spot, and the subsequent treatment of the soil with 
some approved insecticide, such as carbolic acid, would 
be of great importance. 
A communication from M. Louis Faucon, who has 
practised the method of submersion with success,, was 
recently laid before the French Academy (Comptes 
Rendus, 9th September, 1872), in which the important 
fact, ascertained apparently with certainty, is an- 
nounced that the Phylloxera, in migrating from 
diseased to healthy vines, comes to the surface of the 
ground during sunshine. Its dispersion is also, no

roots as well, and, as the vine is notoriously sensitive 
in cultivation to influences injuriously affecting its
