regions under more or less similur conditions. A tem- 

 perature of 55° to GO" at night, and correspondingly 

 higher during the day, will suit most species. An abun- 

 dant supply of air and light, though in partial shade, is 

 indispensable. Water must be used freely during the 

 growing season and somewhat reduced during their 

 respective resting seasons. An occasional dipping in 

 manure water (either cow or sheep manure) will greatly 

 assist these plants in bringing to perfection their 

 flower-spikes, which are oftentimes very large. In a 

 good many species the flower-spikes are out of all pro- 

 portion to the size of tlie plants, and unless they are 

 assisted as indicated, they will very soon run out. 



For potting, use very soft fibrous peat, with a sprink- 

 ling of live sphagnum. Pot firmly, or the plants will be 

 very slow in taking hold. John E. Lager.
