Bark-Round

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 exudations will follow. It is a sure indication that either the soil is loo rich, or not sufficiently drained; the latter is usually the source of the evil, causing a repletion of the interior vessels which the dry cuticle cannot expand sufficiently quickly to accommodate. Under-draining, and scrubbing the stem with brine or soft soap, speedily effects a cure. Scoring the. bark lengthwise with a knife is a usual remedy, and generally effects the purpose.

Barking Irons

Barking Irons, or Bark Scalers, are for scraping off the indurated epidermis, or dry scales, from the stems and branches of trees.

Bark Stove

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 atmosphere constantly saturated with moisture, 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 heat employed. (See Stove).

Barkeria

Two species. Stove epiphytes. Division. Peat and potsherds, or wood.

Barleria

Fourteen species. Stove evergreen shrubs, except B. longi-folia, which is biennial. Cuttings. Loam and peat.

Barnadesia

Barnadesia rosea. Stove evergreen shrub. Cuttings. Rich loam.

Barnadia

Barnadia scilloides. Half hardy bulbous plants. Offsets. Peat and loam.

Barren Soil

No soil is absolutely incapable of production; and when it is spoken of as being barren, no more is meant than that in its present state it will not repay the cultivator. The unproductiveness arises from a deficiency of some of the earths; from an excess or deficiency of animal and vegetable matters; or from an excess of stagnant water. No soil can be productive where nineteen parts out of twenty are of any one earth or other substance. If either chalk, or sand, or clay, be in excess, the remedy is found in adding one or both of the other two. An excess of organic matter only occurs in peat soils, and these are reclaimed by draining, paring, and burning, and the addition of earthy matter; drainage is also the cure for an excess of water.

Barringtonia

Barringtonia speciosa. Stove evergreen tree. Cuttings. Loam and peat.

Bartholina
