After several years successful cultivation of grape vines under glass, I should think that the method of glazing vineries spoken of by Mr. Williams in the March number of The American Garden, hardly a good one. While there may be times during a season that it is advisable to have plenty of air in the grapery, I prefer to have it more directly under my control. The same may also be said of the water ; if during the time the vines are blooming the weather should be wet and cold, as is sometimes the case, I fear that with the glass at all apart so that there would be much leakage, the result would be a bad set of fruit, especially in the more tender varieties. A grape roof, in my opinion, should be as nearly water tight as possible if the best results are to be expected. If a person is going to depend on an open roof through which to supply his vines with air, and the inside border with water, be need not be disappointed if he is not as successful with his vines as some of his neighbors, who attend more closely to the watering and airing of the vines. - R.
