dication that either the soil is too rich, 

 or not sufficiently drained; the latter is 

 usually the source of the evil, causing a 

 repletion of the interior vessels which the 

 dry outer skin cannot expand sufficiently 

 quickly to accommodate. Under-drain- 

 ing, and scrubbing the stem with brine, 

 speedily effects a cure. Scoring the bark 

 lengthwise with a knife is a rude mode 

 of treatment often followed by canker, 

 more fatal than the disease intended to 

 be removed. If scoring be adopted it 

 should be early in spring, and the knife 

 should not penetrate below the dry outer 

 bark. 



BARK STOVE, or Moist Stove, is a hot- 

 house which, either by having a mass of 

 fermenting matter, or an open reservoir 

 of hot water within-side, has its atmos- 

 phere appropriately supplied with mois- 

 ture, congenially with the habits of some 

 tropical plants. It received the name of 

 Bark Stove, because tanner's bark was 

 formerly a chief source of the heat em- 

 ployed. See Stove.
