secure a nice luit-culoureJ libvous heath soil. For the free 

 growers about one-sixth of silver sand should be mixed 

 with the peatj and for the slow growers about one-fourth. 

 The ])lauts must be re-potted annually until they acquire 

 considerable size, when it may be advised to keejj some of 

 them in their p(jts two jears, but refreshed by renewal 

 of tlie top soil. Any excess of moisture is injurious to 

 heaths; on the other hand, if kept too dry they will become 

 rusty and cast their leaves. The proper place for a collec- 

 tion is an airy span roof house, where they should always 

 be freel^r ventilated, and have only as much artificial heat 

 as will keep them safe against frost. Daring July and 

 August it is advisable to keej) them out of d(_)ors, so placed 

 that worms cannot enter the pots and the mid-day sim 

 cannot scorch them. Indeed, all extremes of heat and 

 cold and drought and humidity must be carefully avoided. 

 The best free-growing kinds for a beginner are Bnwieuna, 

 Crueniii, Exsnrijens, Flammea, Jiefnhjeiis, iriliiioreaiia, Iii- 

 ieniiedia, Bergiana, Gnieilis, G-raiiills.nina, lli/eiiiuHs, Liii- 

 neana, l-'i/raii/iihilis, and Snljjl/iirea.
