the beneficial effects of an improved system, they very slowly and 

 reluctantly adopt it. 



Future improvements in the culture of the vegetable-garden may 

 be looked for through a better knowledge of the application of manure, 

 both solid and liquid. Half the benefit which might be derived from 

 manure is lost through a want of this knowledge. I have seen the 

 ill effects of an application of strong liquid manure to a crop, which 

 it nearly killed, when the soil was very dry ; but used equally strong 

 when the soil was in a moist state, its beneficial effects were clearly 

 distinguished. This points out the time it should be used ; the soil, 

 even in a wet state, will absorb the most valuable portion of the 

 liquid. A system of underground and surface irrigation would also 

 be a great improvement in vegetable culture, more particularly the 

 former. Surface-watering in very hot weather is of very question- 

 able service, sometimes positively injurious ; underground irrigation, 

 on the contrary, would be of the greatest service, without a possibility 

 of a single objection being raised against it.

TEA ROSES. 



Having for the last three or four years devoted some time and atten- 

 tion to the cultivation of that fine class of Roses, " the Tea-scented," 

 I send you a list of a few of the best and most distinct varieties which 

 I have found well adapted for pot-culture, thinking it may be useful 

 to some of your readers in making a selection from the numerous 

 (and in many cases comparatively worthless) varieties which now 

 swell out our Rose-catalogues to such a ridiculous extent. 



Adam . . . Pale blush. 



Bougere . . . Rosy fawn, large. 



Devoniensis . . Creamy white ; best of the class. 



Elise Sauvage . . Yellow, orange centre. 



Eugene Desgaches . Rosy blush, very fragrant. 



Moiret . . . Fawn and yellow. 



Niphetos . . . Pale lemon. 



Souvenir d'un Ami . Salmon. 



Safranot . . . Apricot; changes to buff. 



Vicomtesse de Cazes . Bright yellow. 



These are all free growers, either on their own roots or on the 

 Manetti stock, and with proper treatment will flower abundantly. 

 To complete the dozen, I should add Madame Willermorz, white, fawn 

 centre ; and Smith's Yellow, which, though apt to produce a green 

 centre, is, when perfect, inferior to none. By means of a well- 

 arranged succession of these varieties, the conservatory may be sup- 

 plied throughout the greater part of the year with this queen of 

 flowers, which certainly forms one of its most charming and fragrant 

 attractions. 



Niphetos.
