Sir: I beg to claim your indulgence, while I trouble you with a few questions, an answer to which, either yourself or some of your able correspondents, will perhaps, kindly furnish through the Horticulturist. I entered a situation near this city, on the 2nd of August last; I have under my care three grape houses - the houses have a lean-to roof, and the vines planted some in the house and some out; the greater part of the vines are foreign; some Sweet Waters planted three or four years ago, bore a few bunches - but every leaf on the vines dies,scorched very much ; some young vines,also foreign, planted in the spring of 1851, were the most miserable things I ever saw, every leaf burned and scorched, and only made two or three feet of miserable poor wood. I have had vines under my care for twenty years in England, and never saw anything like this. I only arrived in this country last May, and consequently have not had any experience here. The border, I am told, is thoroughly drained and made of rotten manure, and light sandy peat; I am told by my predecessor, that the vines have been liberally supplied with water j I have no thermometer, but I am sure the heat must be above 100° often, and my impression is that the sun is too powerful for them; in this, my predecessor does not agree.

I may say the Isabella and Catawba grapes, are in a flourish-ing state by the side of these vines; the vines have been pruned on the spur system. I should be glad to know of a radical cure for this. I should be glad to know if any of your correspondents have had any experience with canvass for a shade for foreign vines. The situation is near the lake shore; the sorts of foreign vines are Muscat, Black Hamburg, St. Albans, Frontignan, etc. I see no difference in the sorts. The vines arc trained some on rafters and some on the back wall. I am,sir,your obedient servant, C. Chicago, III.
