 dom lasting above a month, or six weeks ; it 

 consequently will not answer, where these con- 

 veniences are not to be had. The plants being 

 regulated in proper order as before, let them 

 have the usual treatment until the time of shift- 

 ing i to perform which, ample directions have 

 been already given. In all cases where tan is 

 mentioned as a necessary assistant in support- 

 ing the internal air of the house, let it be under- 

 stood, that leaves, or very well prepared dung, 

 will be a good substitute where that article 

 happens to be difficult or expensive to procure : 

 there should, however, be a sufficient depth of 

 saw dust, or tan, on the surface to plunge the 

 pots in. 



Thus, having gone through a regular series 

 of work, necessary to be done in the Hot-house 

 throughout the year ; I shall next proceed, to 

 that requisite to be followed in the Green-house 

 department ; in doing which, I shall endeavour 

 to follow the same explicit plan, which has been 

 hitherto observed.
