Ill 
shall remain lying about in the vineyard. Likewise in hewing must all 
resulting wood fragments be scrupulously gathered and immediately 
removed. All stocks once attacked by the disease must be pulled out 
and burned as soon as possible—all still existing roots, with the very 
utmost speed. Finally, moreover, care must be taken in the removal of 
vine stakes at the beginning of the winter that the points, sometimes 
broken off in this way, are not left in the ground. Were it in general 
practicable, from local or pecuniary reasons, to remove the vine palings 
entirely and substitute cultivation upon wires, then certainly one chief 
source of infection would be entirely removed. In conclusion, it may 
also be mentioned that where persons do not feel able to do without 
forest litter in the cattle stables and the use of the resulting manure 
in the vineyard, a frequent scattering of Stassfurt fertilizer or kainit in 
the stables and on the dung pile will result in good, as thereby, the be¬ 
ginning of this fungous mycelia will be hindered.” 
Three other underground parasites are considered— Phasmodiophora , 
Dermatophthora necatrix , and Bosellina quercina; but no mention is 
made of Agaricvs melleus or of Hartig’s Trametes radiciperda , which Bre- 
feld now says (vn, p. 14) should unquestionably be referred to Poly- 
porus annosus , Fr.— Erwin F. Smith.
