«ioiith, when directions for that operation will be 

 given. 



Of screening the Plants in bod IVeatlier. 

 If tlie weather be severe, be attentive to draw 

 tlie side-curtains at night (see Section III.)» lest the 

 plants in the border behind the parapet be aflected 

 by frost; but let them be undrawn betimes in the 

 morning, for tlie free admission of light, which is 

 the more necessary at this dark season. Blinds or 

 curtains, as noticed in Section III. are Aery useful, 

 and also very safe for plants situated near the up- 

 right glasses, in cases where the flue is removed to 

 a distance from them ; and they may easily be fit- 

 ted to t!ie lights of any house not provided wdtli 

 them. Blinds, however, neatly moimted on rollers, 

 and fixed under the beam, are to be preferred to 

 curtains tliat draw to one, or to either side, being- 

 less liable to shade tlie plants, when roiled up in 

 the dav, tiian the curtains are, when drawn. * 



* The patent window blinds of Mr James Thomson of Edin- 

 burgh, are the most complete thing of the kind I know, and 

 jmjght answer in every respect for the lights of hot-houses.
