remains a mystery. I have surrounded the roots with 
a bed of soot, overlaid with earth ; but whether the 
vine will recover or die remains to be proved. 
I have, &c,

Consul Crawfurd to Sir C. Murray. 
Oporto, 30th June, 1872. 
Sir, 
I have the honour to enclose herewith, with 
reference to your despatch of the 12th instant, a 
Keport upon the recently discovered vine-disease 
producing insect — Phylloxera vastatrix. 
I have, &c,

[Inclosure 2 in No. 3.] 
Report by Consul Crawfurd upon Phylloxera 
vastatrix. 
The attention of the Portuguese wine-growers has 
not been called until the last two years to the existence 
of a new enemy of the vine in the shape of Phylloxera 
vastatrix. 
The discovery in France of this supposed importa- 
tion from America was not made till the year ]855, 
since which time its natural history and the effect of 
its ravages upon the vine plant have been industriously 
investigated by French entomologists and cenologues ; 
and in the opinion of some persons the extent of these 
ravages has been not a little overstated.
