W. H. W., Maiden, Mass., says: - "Will you please tell me, either by mail or through the Gardener's Monthly, at about what temperature a cold grapery should be kept?"
[A cold grapery, as generally understood, has no fire. It is simply the foreign grape-vine, growing in the open ground, and covered by glass, so as to keep the atmosphere moister than the unaided American climate affords. No especial temperature is aimed at. The sash is lowered somewhat, or the upper ventilators left open, and the glass somewhat shaded if the sun is likely to run the temperature in summer much above 90°. The lower ventilators, if any are there, are not opened, as this causes the moisture to escape too rapidly, and thus defeats the very object of the glass house. - Ed. G. M.]
