COOL GREENHOUSE. 113 



the greenhouse, and when the bulbs begin to push 

 through, dip them for a few minutes in water. Keep 

 well supplied with water when growth is active. After 

 flowering, gradually withhold water. Keep dry till repot- 

 ting time. Temperature in winter, 45 to 50 deg. ; in 

 summer, 55 to 65 deg. Propagation is effected by offsets 

 removed from the old bulbs at potting time ; also by seeds 

 sown in a temperature of 55 to 65 deg. in spring. Seed- 

 lings flower when four years old. 



Liiium. There are a few species of Liliums that are 

 specially adapted for culture in a cool greenhouse. They 

 are too tender to grow outdoors or in a cold house. The 

 kinds here referred to are : Harrisii or eximium (Easter 

 or Bermuda Lily), white, 3ft.; neilgherense, sulphur 

 (autumn), 3ft. ; nepalense, yellow and purple (autumn), 

 4ft. ; Lowii, white and violet (summer), 2ft. ; philippinense, 

 white (August), 2ft. ; sulphureum (Syn. wallichianum), 

 yellow and brown (summer), 6ft.; and longiflorum Wil- 

 sonii, white (spring), 3ft. 



L. longiflorum and Harrisii do best in a compost of two 

 parts turfy loam, one of leaf -mould, and a fair quantity of 

 silver sand. One bulb may be grown in a 6in. pot, or 

 three in an Sin. size. Provide good drainage, put in 

 two inches of compost, then the bulb or bulbs; surround 

 each with a little sand, and add sufficient compost to just 

 cover the bulbs. The remaining space in the pots should 

 be left to accommodate a top-dressing when the shoots are 

 six inches high, and stem roots have begun to form. The 

 other lilies will require a compost of equal parts of loam, 

 peat, and" coarse silver sand. In potting treat L. nepa- 

 lense as advised for the longiflorum varieties, because this 

 is a stem-rooting species. The others do not require to 

 have their bulbs placed so low in the pot, or to have so 

 much space left for top-dressing. If the apex of the bulb 

 and the soil be brought to within an inch of the rim this 

 will suffice. The time for potting will depend on when
