Dear Sir - I suspect your correspondent, H. B., has got the prying faculties very largely developed, as he inquires so very particularly about the "two stoves" which were used in the cold vinery at this place, in the earlier part of last season; and as persons of this description are apt to be uneasy until their wishes are gratified, I hasten to relieve him of his unpleasant anxiety. As I have no secrets in my practical working, and do not wish to conceal any minutiae in my operations, that will be of service in disseminating useful information, I feel obliged to him for reminding me of an omission, (if it can be construed into such a form,) but the matter was of so trifling a character, that I did not think it of sufficient importance in the detailed account sent you. When writing that account, I had embodied a few general remarks on cold graperies, in which were mentioned explicitly, these two stoves; but as the article seemed swelled out into an inconvenient length, these remarks were extracted from it, with the intention of sending them at a future opportunity, thinking that your readers, who he says "are interested in the matter," might be more benefitted by it in that form - and as I do not like to occupy at the present too much of your valuable space - I will extract the passage, (with your permission,) from manuscript in which the two stoves are mentioned, and which runs as follows:

" I would remark, that however long we may try to retard vegetation, the buds of the earlier kinds will begin to burst before the occasional frosty nights and north-east storms of the latter part of April, are past, and for safety, a temporary heating apparatus of some kind will be of service at this time, merely to be ready in case of need. To answer this purpose, there were put up in the house at this place, two common stoves, which enabled me to raise the temperature five or six degrees during several frosty nights, and also once in the day, when there was snow and frosty wind all day. It would also be of service in cloudy, damp weather, during November and December, to dry the air of the house, and prevent mouldiness in the grapes. At no other is it required, as we have natural heat and light sufficient, if made good use of, to ripen the grape perfectly".

These two stoves stood in the house about three weeks, but were not lighted more than six times during that time, and only when the thermometer outside sunk to the freezing point; they were only used once in the day time, when there was a severe snow storm, with. frosty wind, and it was only to keep the frost from killing the bursting buds, that the idea of having them was suggested. There was not consumed more than 150 pounds of coal, and as I employ my time as usefully as possible, and hare no opportunity to trifle, I send H. B. the dimensions of the house in which 150 pounds of coal was consumed: it is 74 feet long, 20 feet wide, and 14 feet high, with glass on all sides, and ask him to be kind enough to work out the mathematical problem of how far it will give " artificial heat, and to what degree on an average." That he may not err in his calculations, he must allow for the exposed situation of the house, which, if I am not greatly mistaken, he is aware of.

As to the point at issue, viz - cutting ripe grapes on the second of August, (not, as he erroneously states, the first,) without artificial heat, it is the most simple part of the business; and it strikes me forcibly that he writes without much experience, or he would well know that the kinds mentioned, (Malvasia, and Joslin's St. Albans,) maybe ripened so early without any fire heat whatever. Those same grapes were ready to cut a week earlier, but as my employer was from home at the time, they were reserved till his return; so that allowing for the six nights and one day that the stoves were lighted, the argument will stand about " zero" in his favor. The season in which the vines were planted, 1850, no stoves were used, and I cut several bunches from tubs planted the same spring, the latter part of July. There has not been either, any fire heat of any kind, this season, and the vines are growing very vigorous, and many have shown from fifty to over sixty bunches, generally speaking, stronger than last year.

Hoping I have explained all to the satisfaction of your correspondent, 1 am yours respectfully, Wm. Chorlton, Gardener to J. 0. Green, Esq., New-Brighton, Staten-Island.

May 1,1852.
