MARCH. 



The annexed cut may represent 

 perhaps the cheapest and best way 

 of covering a 12 feet wall with a 

 glass front, a being the glass, 

 which should be fixed at once on 

 sash -bars, 10, 12, or 15 inches 

 wide ; the glass should not overlap, 

 but be laid on strips of India-rubber, 

 placing another strip over the glass, 

 on which a bead should be screwed, 

 so as to keep the whole tight, b is 

 the top ventilators, hung on to a 

 plate against the wall with hinges. 

 The dotted lines represent them as 

 opened, c is for ventilation at bot- 

 tom, which should consist of louvre 

 boarding, to open and shut when 

 wanted, by means of wires from 

 within, or it may be formed of slid- 

 ing boards. 



Our remarks have been en- 

 tirely confined to the benefits to be 



realised from employing glass alone, unassisted by artificial heat; 

 but where hot water or flues can be introduced, the last description 

 of house would be found one of the cheapest modes of forcing grapes 

 and other hard- wooded fruit-trees, and quite as capable of producing 

 fruit of good quality, as houses built from far more expensive de- 

 signs ; but we reserve our observations on this point to another 

 opportunity. John Spencer.

THE GENUS KALOSANTHES. 



Some of the species of this genus are amongst the most showy and 

 fragrant of summer-flowering plants, and they deserve to be more 

 generally cultivated than they have hitherto been. The magnificent 

 specimens annually produced at the great metropolitan exhibitions 

 in July indicate the capabilities of the genus, and good plants are 

 frequently produced far from the scene of these meetings. I doubt, 

 however, whether any genus equally deserving attention is so com- 

 monly neglected or mismanaged by country gardeners as this. With 

 a little care the flowers remain in perfection for some six or eight 

 weeks, and the plants Avill be found exceedingly useful in the show- 

 house, to take the place of the Azalea, when the beauty of the latter 

 is over. 



Young plants intended for specimens should be dwarf and bushy, 

 with strong well-ripened wood ; those that may have been wintered 

 in a soft, half-growing state should be rejected, as it is diflicult to get 

 them to break freely or grow vigorously. Place them early in March
