is applied in the same way as the ordinary sulphide, depositing some 
at the foot of the vine stock and spreading the rest over the surface; 
this treatment is found to be effectual; with it Phylloxera is no 
longer seen in the roots, vegetation is luxuriant, and numerous new 
rootle s indicate a decisive increase in vitality ; the manuring on a 
test tract of land had not been altered for six years, therefore the 
improvement was solely due to the insecticide. — P. Cazeneuve.

Bisulfide of Carbon. — This is the great French remedy for the 
phylloxera, 150,000 acres being now subjected to treatment with it, 
and applies equally well to all other root-inhabiting lice. The 
treatment is made at any season except the period of ripening of 
the fruit, and consists in making holes about the vines 1 foot to 16 
inches deep and pouring into each about one-half ounce of Bisulfide 
and closing the hole with the foot. These injections are made about 
1 '/z feet apart, and not closer to the vines than 1 foot. It is better 
to make a large number of small doses than a few large ones. 
Hand injectors and injecting plows are employed in France to put 
the Bisulfide into the soil about the vines, but a short stick or iron 
bar may be made to take the place of these injectors for limited 
tracts. 
For root maggots a teaspoonful is poured into a hole at the base 
of the plant, covering as above.
