tial renewals, the bed requires only to be 

 excited to a brisker fermentation by fork- 

 ing up. About live-sevenths of the pit 

 from the bottom should be occupied by. 

 the new and old tan as a fermenting 

 body ; and about two-sevenths from the 

 top, or a little more than the depth of 

 the pot, whatever that may be, should 

 consist of old tan incapable of heating, 

 so as to burn the roots of the plants. At 

 least, such should be the ordinary distri- 

 bution of the tan; but, where peculiar 

 circumstances require a speedy augmenta- 

 tion of heat without displacing the pots, 

 and when fruit is to be swelled off in the 

 last stage, the earthy tan at top may be 

 taken away, and new tan substituted.

BARK-BOUND. When a tree is affected 

 with this disease, cracks will appear in it 

 partially, and, in the case of the Cherry, 

 Apricot, Peach, and Nectarine, gummy 

 discharge will follow. It is a sure in- 

 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 suffi- 

 ciently quickly to accommodate. Under- 

 draiiiing, and scrubbing the stem with 

 brine, speedily effect a cure. Scoring the 

 bark lengthwise with a knife is a rude 

 mode of treatment, often followed by 

 canker, more fatal than the disease in- 

 tended 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 atmo- 

 sphere 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 <niief source of the heat em- 

 ployed. See STOVE.
