much growing wood close to the ground 

 there will be more difficulty in keeping the 

 fruit clean than where a hig-her system is 

 adopted, and the tieing is somewhat incon- 

 venient. 



Manuring. — The fertilising treatment ac- 

 corded to the grape should be on as liberal 

 scale as that g^iven to other fruits. Where 

 a big growth of wood is being made it is a 

 sign that enough nitrogen is present in the 

 soil. Additional barnyard manure is not 

 necessary, and will in fact tend to promote

an overgrowth and induce mildew. A heavy 

 dressing of ashes, or muriate of potash will 

 then give excellent results, the grape being 

 one of the heaviest consumers of potash of 

 all fruits. 



Varieties. — A good list for the commer- 

 cial grower is the following : 



Black. — IVordeft, Roger 4, Roger 44, Con- 

 cord. 



Red. — Wyoming Red, Roger g [Lind/ey), 

 Delaware, Roger 75 (Agawam), Vergennes. 



White. — Niagara, Moore's Diamond. 



Many varieties of grapes have imperfect 

 blossoms, and where this occurs, other var- 

 ieties of a self-fertile character should be 



planted near. Rogers 4, Salem, Brighton, 

 and Rogers 9 {Lindley), will be unsatisfactory 

 when planted alone. Niagara and Delaware 

 have an abundance of pollen, and Concord, 

 Roger ij, Vergennes and Warden will fruit 

 satisfactorily alone. 



List of varieties for home use : 

 Black. — Moore's Early, Worden, Rogers 4 

 arid 44. 



Red. — Brighton, Lindley, Delaware, Salem. 

 White. — Niagara, Moore's Diamond. 

 With respect to this list, it may be added 

 that Vergennes is a good 

 bearer, fair quality and ex- 

 cellent keeper, but it ripens 

 too late for many sections. 

 Moore's Early, although a 

 good early black grape for 

 the amateur, is not vigor- 

 ous or productive enough 

 for the commercial grower. 

 Wyoming Red is early and 

 prolific, but poor quality. 



Diseases. — Black Rot, 

 Brown Rot, or Downy Mil- 

 dew, Powdery Mildew, Yel- 

 low Leaf, Anthracnose, 

 called Bird's-eye Rot when 

 attacking the fruit are the 

 more common. It would take too long in a 

 brief practical treatise, such as this, to describe 

 different diseases. Readers are referred for 

 full information to Bulletin 92 of the Ontario 

 Agl. College and to " Fungous Diseases of 

 the Grape and other Plants," by Professor 

 Lamson-Scribner. Yellow Leaf is a disease 

 of comparatively recent origin and little is 

 know of its nature. The bright yellow color 

 of the foliage, the shrivelling of the berries 

 and the dying condition of the vine readily 

 indicate the trouble. It is advisable to up- 

 root diseased vines and reset with healthy 

 plants. Bordeaux mixture is the standard 

 remedy for the rot and mildews. For the 

 common form — the Powderv Mildew — ordin-
