by Mr. Maund, the author of that most 

 useful periodical the Botanic Garden : 

 ** Grapes grown on open walls in the 

 midland counties are rarely 

 well ripened; therefore I 

 provide a small glazed 

 frame, a sort of narrow 

 hand-glass, of the shape 

 shown in the annexed out- 

 line, to fix against the wall, 

 and enclose one hranch of 

 the vine, with its fruit and 

 foliage. The open part, 

 which rests against the wall, 

 is thirteen inches wide, and 

 may be of any length re- 

 quired to take in the fruit. 

 The sides are formed of 

 single panes of glass, seven 

 inches wide, and meet on a bar which 

 may represent the ridge of a roof, the 

 ends enclosed by triangular boards, and 

 having a notch to admit the branch. 

 This is fixed on the branch a month be- 

 fore the vine is in flower, and brings it a 

 week earlier than the exposed. The 

 frame is not fitted closely to the wall, but 

 in some places may be a quarter of an 

 inch from it. The lateral branches being 

 shortened before it is fixed, it does not 

 require removal even for pruning, because 

 I adopt the long-rod mode of training, 

 which is peculiarly adapted to my partial 

 protection system. The temperature within 

 the frame is always higher than without, 

 sometimes at mid-day even from 20 to 

 30. By this simple protection I find 

 grapes may be ripened from three weeks 

 to a month earlier than when wholly ex- 

 posed, and this saving of time will, I be- 

 lieve, not only secure their ripening well 

 every year in the midland counties, but 

 also that such advantage will be available 

 in the north of England, where grapes 

 jiever ripen on the open walls." 



Lastly, there is the Wardian-case, to 



cover plants growing in rooms, preserving 

 to them uniform moisture, and excluding 

 dust. To prevent the dew which is oc- 

 casionally deposited inside the glass, it is 

 only necessary to open the case frequently, 

 for a few minutes, to render the tempera- 

 ture within similar to that outside. They 

 are not intended to exclude the air, and 

 are now made very ornamental.
