The Orchid-house 



with perforated zinc, which does uot obstruct the 

 air, but excludes slugs. 



The pathway should be 4 feet wide, with a stage 

 on either hand 5 feet in breadth towards the wall, 

 6 feet towards the front. 



The height of the house, and the width of the 

 pathway, allow plants to be hung from the roof 

 neatly and conveniently. This is an immense 

 advantage. Very many species must be suspended 

 near the light, with the air freely circulating round 

 them, to thrive as they should. 



This is the best position also for seedling orchids. 

 The seed should be strewn over the surface of pans 

 thus suspended. 



The staging should be double, as shown in the 

 plan, t(_) secure an equable temperature and con- 

 stant humidity. 



A tank for rain-water, 6 feet by 16 feet, should 

 be provided at the far end of the house. This is so 

 imj)ortant, that one tank represents the minimum 

 desirable. 



It is a great mistake to grudge piping; super- 

 fluous heat can always be turned off, but a deficiency 

 cannot be supplied. Have the boiler rather too 

 strong than too weak. Such a house as we have 

 sketched, devoted to Cattleyas and Laelias, should 

 be fitted with ten -i-inch pipes, flow and return;
