It is under glass only that Grapes can be brought to perfection. Here a night temperature of 55 to 65 degrees, with a rise of 5 or 10 degrees in the day, should be maintained, the walls and paths damped once or twice a day, and the vine syringed frequently until it comes into bloom, when syringing must cease, and a drier atmosphere is necessary; the moisture being reduced by degrees. As the grapes ripen, admit more air, and reduce the heat, otherwise the fruit will shrivel. After gathering the grapes syringe the vine frequently to clear it from spiders or dust, and keep the house cool to induce rest to the plant. The fruit may be preserved for a long while in a good condition by cutting it with about 1 ft. of the rod attached, and inserting the cuttings in bottles of water in which a piece of charcoal is placed: the bottles to be placed in racks nailed on to an upright post in any room or cellar where an equable temperature of 45 or 50 degrees can be kept up. The system of pruning adopted is that known as spur pruning (_see_ "Pruning"). Mrs. Pearson is a very fine variety, and produces very sweet berries; the Frontignan Grizzly Black and White are also delicious.
