Let them be kept under the glasses as long as possible, without danger of injuring them, admitting a small quantity of air in the day-time, when the weather is warm, by means of a piece of wood, in the form of a wedge, about seven inches long, five inches wide, flat, and about three inches at the top. This will enable you to rise or fall the glass according to the quantity of air necessary to be admitted. Before placing the vine outside the glasses, it will be necessary to admit a larger portion of air, both night and day, for three or four days, in order to harden the plants; then mulch the bed all over with litter, which will cause the fruit to be kept clean, and the roots moist, an essential requisite in the culture of cucumbers. Though moisture is so extremely necessary, yet at all times in the application of water you must be regulated by the temperature of the season. If the weather is hot and dry when they come into full bearing, from three to four gallons of water will be required to each glass every two or three days, if the soil is light, but if of a strong loamy nature, less will be sufficient. Lay out the vines regular, peg them down, and place four half bricks, that is, one to each corner, under the frame of the glass; or another method may be adopted, in raising the glass to the south by means of a piece of stick, about the thickness of a broom-stick, a foot in length, with three notches cut in it, about two inches apart, for the purpose of resting the glass upon. This plan is far preferable to the former, in materially accelerating the growth of the fruit, by preventing too great a current of air; besides possessing the advantage of easier access to the plants, when there is a necessity for examining them. It is, however, requisite when this method is adopted, that the ridges should always front the south. If the above directions are strictly attended to, and the season is in any degree favorable, a plentiful crop of fine fruit may be expected.
