242 GUIDE TO THE CONSERVATORY. 



Orchideae require a certain degree of shade. 

 Some persons grow them in a north aspect, but I 

 prefer Messrs. Loddiges' mode of giving shade to 

 any other I ever saw : it is by placing the plants 

 on the north side of their palm house : in this si- 

 tuation they receive that kind of shade which they 

 have in their native country. When I saw the 

 plants they were in fine condition. 



Season of Rest. — It is highly beneficial to give 

 the plants a season of rest, as by it they are not so 

 much exhausted as when continually excited with 

 heat and water. It is usual to put them on shelves 

 in the house w T hen in a dormant state ; and, where 

 convenient,, the heat should be from 55° to 60°, 

 this temperature being sufficient for the plants 

 when in their state of rest. 



Water. — When in a vigorous growing state, they 

 will require it to be given with a liberal hand ; but 

 when dormant, only a little will be necessary. A 

 moist atmosphere, particularly in the evening, is 

 very beneficial to them.
