authority on the subject in Europe, and his opinion confirms the 
views of the commission in the amplest manner. Dr. Cornu 
says: “I made the most minute and careful survey of the vines 
said to be so affected, and came to the decided conviction that the 
Phylfoxera did not exist on the vines in question.”—Zastern

RESISTANCE OF GRAPE-VINES TO PHYLLOXERA IN SANDY SOIL.— 
The immunity from the attacks of Phylloxera enjoyed by grape- 
vines when planted in sandy soil has long been known, and has 
been attributed to various causes. M. Saint-André, of Mont- 
pellier, France, discusses this subject in the Messager Agricole for 
May 10, 1881, and believes that neither the mobility nor the an- 
gulosity of the particles of sand, nor the absence of cavities, nor 
the chemical composition of: sandy soil are sufficient reasons. 
Nor is the presence of a subterranean current of water in sandy 
soil an admissible reason, since it has been proven that the quan- 
tity of water contained in such soils at different depths and at 
different seasons is always smaller than that contained at the 
same period in other soils where the presence of Phylloxera ren- 
ders the culture of the grape-vine impossible. He believes, how- 
ever, that the circulation of water in the soil is a matter of the 
first importance in regard to the presence of Phylloxera, and that 
disappearing under the attacks of the insect. Between the two 
limits above given, the plants suffer more or less. Exact peor
