The system of growing grape-Vines, and other fruits, in pots and tubs, for early forced crops, presents many advantages over the old method of fruiting plants permanently set out in the soil. The roots are thus equally under the control of the operator, and a uniform and successful crop can with more certainty be insured.

The " Golden Rule" in forcing is never to be in a hurry, and to endeavor to imitate somewhat the fluctuations of the external atmosphere; especially allow a reasonable fall of the temperature in the absence of light; the night temperature should fall from 15o to 20o below that of the day in clear, sunny weather. Many failures in forcing are caused by high night temperature, and a mistaken eagerness to keep plants in an artificial instead of a natural condition.

Strawberry plants potted in the fall, will fruit well in a greenhouse, if placed on a shelf near the glass. The hermaphrodite varieties succeed best, as the pistillate do not set freely unless artificially impregnated. Much has of late been written on the subject of sexes in strawberries, but very little of any practical value. It is perfectly in accordance with the teachings of vegetable physiology that single and double, or perfect and imperfect, flowers may be produced on the same plant. The production of wood buds or flower buds is also within the power of the skilled cultivator. Under shelter of these well known botanical laws, assertions have been made that the inconstancy of the strawberry is so great as to render all distinction of sexes worthless. This assertion is simply absurd, as all practical cultivators well know; and it is equally absurd to maintain that changes are impossible.
