acres of grapes in ground vineries in some favoralile 

 locality. To form the vinery Xn. 1, p. 125, two seven- 

 feet lengths are required; these I find from exjje- 

 rience are better made of wood than iron, which is 

 heavy and expensive ; they are now made three feet 

 wide at base, and sold by ]Mr. -T. Jiivctt. Stratford, 

 Essex, at from ri5,x. to TO.v. per dozen, \u\'^]:i7j:d and 

 unpainted. Their size may also be increased to 3 t'uL-t 

 6 inches, as in No. 2, but tlicy must then be placed 

 on a wall two bricks in height, leaving apertures, four 

 or five inches wide and six inches deep, for ventila- 

 tion ; this increase of ventilation is al)Solutely neces- 

 sary with Xo. 2. The ^'lass used shoold be 21 oz., as 

 16 oz. is too sliiiht. As the vines in ground \-ineries 

 often put forth tlieir young shoots early in May, and 

 are apt to be injured by a severe May frost, it is good 

 jiractice to keep some refuse hay strewed over the 

 glass wlicn tliere is any ebanee of fm-t in that month. 

 In gardens wliere these glass ridge roofs are not 

 wanted for ^•ines or fruit tree culture, they will be 

 found most useful. They may be placed on any warm 

 border on bricks ; and early jieas, French beans, and 

 many other early vegetables, re<iuiring protection from 

 spring frosts, be grown under them with advantage. 

 For the cultivation of early strawberries they are in- 

 valuable, as they not only hasten tlie ripening period, 

 but protect tlie fruit from heavy summer shower^, 

 often 80 injurious to the crop, aud also from binls. 

 Strawberry plants, to he cultivated in ground vineries, 

 should lie planted early in autumn, in narrow beds of 

 two or three rows, the plants close together in the 

 rows, so as to take full advantage of the glaAS-eovered
