tree, and there secured, the fruit to be borne on the cane 

 between the trees ; the spur-pruning of this is advised. 

 Another plan of training is, to let the vine run up a^in- 

 glo tree, and branch oif among the limbs which may be 

 well thinned of its branches, to admit the sun and air,

" To prevent the '■ RoP in Grapes. — By a Jerseyman. 

 Dear Sir, — You will probably call to mind a conversa- 

 tion between us, when I was at Newburgh, in 1846. I 

 laid before you an account of the disease which had then 

 made its appearance in our native grapes, — the Isabella 

 and Catawba. It commences about the first of July, in 

 the form of a dark spot upon a few berries. These,

 lime in the form of gypsum, or common ground plaster 

 of Paris ; and you also advised me to use the leaves and 

 prunings of the vines for manure. 



" This is the second season of my trying your advice ; 

 and, as I received it with the promise of making known 

 the results, I accordingly send you a brief statement, 

 which, I think, proves that the advice was good. 



" I have about twenty vines of the Isabella and Ca- 

 tawba grape, in a full-bearing state, trained on upright 

 trellises. In the month of June, (latter part.) 1846, at 

 the time I made the summer pruning of the vines,—
