THE FLORAL WORLD AND GARDEN GUIDE. 5 



alarming, one of Joyce's charcoal stoves was used, and rendered 

 important service. Speaking, however, in a somewhat general way, 

 it is simply the truth to say that the inmates of this house take 

 their risk of weather all the winter tlirough, and during the winters 

 of 1868-4 and 1864-^ were frequently exposed to frost ; and that 

 many rather tender kinds escaped destruction, I attribute to the 

 fact that their roots are imbedded in a mass of brick and earth 

 "which retains a certain degree of warmth, being but slightly in- 

 fluenced by the lowering of tlie temperature of the atmosphere of 

 the house. 



I will now give a list of the ferns which have thoroughly suc- 

 ceeded in this house. Some of them are reputed to be tender, some 

 are known to be hardy, and of the hardy kinds a few are generally 

 considered unsuitable for growing anywhere except in the open air.
