The introduction of new and improved varieties of fruits has of late been so great that there are few persons so well supplied with really excellent kinds, that it will not be to their interest to add to their stock. Those who have a superabundance of Catawba or Isabella Grape-vines, will not regret cutting them down and grafting Diana, Delaware, or the Rebecca, on the stock. By doing so, they will obtain strong fruiting plants after one year's growth. The scions should be secured at once, and preserved in a cool, damp cellar; if a dry cellar, they can be kept in a damp mat, or moistened straw. The object is to keep them from growing until the stock puts forth leaves, when it is cut down, and the scions inserted at once. Cleft grafting is the most simple for grapes, and if the stock is cut low enough to cover the graft with soil, failures will rarely occur.

Greenhouse plants should always be watered in the early portion of the day. In cold weather, early watering allows excess of moisture to evaporate before evening, and the house will better resist cold. Again: In summer, early watering charges the atmosphere with moisture, and the temperature is kept cool and healthful during the day. A more important reason for the practice arises from the fact that the water, and substances it holds in solution, absorbed by plants during the night, is given off again by their leaves, without benefiting the plant. The leaves must be exposed to the action of light, before the carbonic acid and other matters are decomposed. Light is necessary to the performance of those chemical actions which digest and retain the substances required to develop and extend the plant structure. The amount of water given off by the leaves at night, will of course be altogether dependent upon the hygrometric state of the atmosphere.
