42 LILIES 



depth of seil above tke-top- of the biilb should 

 be from-three-to^-seven inches. The normal 

 size of the bulb — some are quite small — and the 

 vigor of the species are determining factors. 

 But there is a -third highly important point to 

 bear in mind. Some lilies root from the base 

 of the bulb only, -while others throTV out later 

 a second set of roots from the stem a little way 

 above 'the bulb. As the stem-roots are vital ele- 

 ments in the production of perfect bloom, the 

 stem^rooting lilies must be planted deep enough 

 to- asoid exposure of this second set. It is diffi- 

 cult to draw a precise line between the two 

 classes, but a fair division, with the inches of 

 soil above the bulb, is as f oUows :
