Is there any rule for the distance of grape vines from the glass in different latitudes?

From my own experience in this part of the state, I would recommend about nine footles, but in a more southern climate, where the sun is more powerful, and there is a longer continuance of heat, I am afraid this is too close, and may injure the vines. Some of my correspondents in the state of Virginia, are anxious to put up warm and cold graperies, and if you have any information on this point, you will confer a favor by replying to this communication tanneries have- now become so common, thai few persons who can afford it, will do without them, when for a moderate outlay, they can have from ten to fifteen pounds a day of the different varieties of this delicious fruit, for many months in the year; and any information as to the character of the buildings, and growth and treatment of the vines, must prove Tsinahic to yo«r subscribers.

These is another point in this connection, to which I beg to ask your attention. Is it advisable to go to the expense of a floe in a cold house, not for the purpose of forcing, but to be used occasionally to get rid of damp and prevent mildew, and also to preserve the crop through the early winter months. In the southern states I should judge there is even greater danger of mildew, almost the only difficulty to guard against in the growth of the vine under glass, and which, in our climate, renders the out-door culture impracticable. At the south they have still more dampness, as is shown by the moss and other parasites with which their live oaks and other magnificent trees are covered; and it appears to me, that a flue for the purposes I have mentioned, will even be more necessary there than here. Yours, T. W. L. Jr.
