different tastes. Nevertheless, most of them can be 

 grown in good loamy soil containing a liberal admixture 

 of grit, if they are planted on sites where the roots can 

 get abundant moisture. They luxuriate in intimate 

 contact with stones, where there is no stagnant 

 moisture to lodge about the collars, and should never 

 be planted in wet places. In short, root moisture and 

 plenty of it, but no surface stagnancy, must be the rule. 

 It is best to wedge them into deep crevices, preferably 

 in positions where overhanging stones will give them 

 a little shelter from the midday sun, and where the 

 roots can ramble afar. They are propagated by seed 

 and division. The former may be sown in pans in 

 early summer and set on a greenhouse shelf or in a 

 frame. Division may be effected in Autumn. 



Carnea is one of the most popular. It is a pretty, 

 free-blooming plant, with pink, yeUow-eyed flowers in 

 late spring and early summer, and pointed leaves. 

 It does not care for limestone, and is almost certain to 

 perish on poor chalky soil, which is much too dry for 

 it. It is best suited by a soil which contains a liberal 

 admixture of peat and sandstone chips. 



Chamaejasme, alluringly named the Rock Jasmine, 

 is a well-known and admired species, bearing crimson 

 flowers in spring. Unlike the preceding it enjoys 

 limestone, but it shares the love of moisture which 

 distinguishes its congeners, and must not be left to 

 look after itself in thin, dry, powdery soil. Loamy 

 soil, with a plentiful scattering of limestone chips on 

 the surface, suits it admirably. Young plants ought 

 to be watered in hot dry weather, but when they are
