While a room is desirable for each group of orchids, 

 it is not necessary, and good results can be obtained 

 with all in one room, if the East Indian and other stove 

 forms are placed at one end, which is kept quite warm, 

 while the Mexican and Peruvian forms are grown at the 

 other. Moreover, the classification is at best a provi- 

 sional one, as some of the stove plants would thrive in an 

 intermediate house, as would several of the cool house 

 orchids. 



THE POTTING OF ORCHIDS. 



Orchids may be grown, according to their nature, 

 upon pieces of bark or cork, or in baskets, pans or pots. 

 The baskets are generally made of cypress or cherry, in 

 a square or octagonal form, or as cylinders, boats, or 

 rafts, as shown in Fig. 44. The material is cut into 

 strips about three-quarters of an inch square and from 

 four inches to a foot or more in length, according to the 

 size of the plants. Holes are bored about half an inch from 

 the end of each stick, and galvanized or copper No. 18
