Account of a new Frame with rising Lights, $c. 131 



unavoidable injury to the plants, and a great sacrifice of 

 time, both of which disadvantages will be obviated ; for the 

 plants may remain untouched in my Frame, and one or two 

 men may raise the glasses of thirty lights in a few minutes ; 

 whereas, to remove the plants contained under half that 

 number, would take the same labourers a whole day ; and 

 the risk of exposing the plants to a chilling atmosphere for 

 many hours, during the operation of removal, will be done 

 away entirely. 



It will be found equally advantageous in the protection of 

 Heaths, through the winter. It is well known that the nearer 

 the plants are to the glass, the greater is the danger from 

 frost, and if they are far from the glass, they are liable to 

 suffer from damp, and from drawing: this improvement 

 prevents all these injuries, for, by raising the lights at night, 

 the plants will be kept at as great a distance from the frost as 

 can be wished, and by lowering them in the morning, the 

 glass will be brought so near to the plants, that they will 

 neither be drawn, nor hurt by damp. 



In growing Cucumbers or Melons, on dung or tan, put into 

 pits of the usual construction, the greatest inconvenience 

 always results from the settling of the dung or tan, the plants 

 being thus carried too far from the glass; by the method 

 now proposed, if the pit is filled high in the first instance, 

 the glasses will always have sufficient room to follow the 

 settling. 



I am so well satisfied of the advantages of the steaming 

 process in the growth of Cucumbers and Melons, that I 

 should consider my plan imperfect without its application ; 

 I have therefore formed it so, that steam pipes may be
