This propheej' was fulfilled, and the tie-less graft is now in general 

 use in all large vine nurs<'ries. When grafting in the field, the whip- 

 tongue grafts may with advantage be a])plicd whenever stock and seion 

 are of the same dianu-ter. It gives the perfection of union ciiaraeter- 

 istic, of bench grafts executed in this way. Only in connexion with one 

 point is care necessary; the very perfection of the fit is a source of

 appearance through the top of the mound. Every precaution must be 

 taken to protect the young growth from depredations of cut-worms 

 (Agrotis caterpillars) and of several beetles which are nearly as trouble- 

 some. These pests are best combated by arsenical poisoning in the
