vex surfacp whoii finished. A plentiful supply of water 

 is essfiitKil :if !il! sp.'isons with copious syringing over 

 the fnliML'.' in liri-ht weather. The compost should 

 never >»■ ,illo\\,,i i.. remain dry for a long time. 



r. ^1. m/,,, :iii,l ^|M cit-s like it grow very well among 

 foli.agr iihiiiis ill ilic warrahouse, where their large 

 aerial roots, whicli are freely emitted from the sides of 

 the stems, may ramhle among the foliage and thereby 

 retain moisture a long time after syringing. A few 

 species, such as V. Amesiana, V. crerulea and V. 

 Kimhalliuiia, with one or two other alpine species, re- 

 quire about ten degrees cooler temperature, but other- 

 wise similar treatment to other species of the genus. 



Stock is increased by removing a foot or more of the 

 leading growth with a sharp knife, allowing several 

 roots to remain attached to each growth and basketing 

 them in the usual manner. These new pieces should be 

 frequently syringed overhead until they become es- 

 tablished or they are likely to shrivel. The old stems 

 will nearly always send out several new growths. 



The principal insect enemies to Vandas are several 

 species of scale, which breed fast in a dry atmosphere. 

 They can be kept in check by syringing with strong 

 tobacco water and by sponging the plants with a 20 

 per cent solution of alcohol. j^^ ]\1_ Grey.
