tempts were and are continually made.* In 
the spring of 1867, we ourselves imported from 
Austria about 300 rooted vines (Veltliner, 
Blue Baden , Tokay, Uva Pana, 
&e.), not with expectations of success in open 
and knowing the true cause, to be then, per- 
haps, able to obviate it. The vines grew 
splendidly, but during the summer of 1869, 
though bearing some beautiful fruit, their fol-

a root-louse (Phylloxera), which bears a close

assisted him to unearth both diseased and 
healthy vines, native and foreign, of every

The French Commission, in its report to the 
Viticultural Congress, held at Montpellier, Oct. 
1874, came to the conclusion that ‘‘In presence 
of the non-success obtained from all attempts 
made since 1868, with a view to preserve or 
cure our vines, and feeling that after six years 
American vines, whether justly so or not, the

_ Congress held at Lyons, France, and at Sara- 
gossa, Spain, in 1880; at Bordeaux in 1881, the 
leading principle established has been: “ that 
the Phylloxera cannot be exterminated where
