Climatic injuries. â Sini- s'-iild and bursting of the bark. â The sweet Cherry is liable to :i fatal injury from sun-scald in The south and prairie states. The trouble occurs in the spring, when the rays of the sun cause alternate freezing and thawing of the growing tissues on the south and west sides. In these localities, the bark of the tree frequently bursts open, and large quantities of gum exude. A rich garden loam, a summer drought followed by fall rain, excessive wood stimulation, violent changes of temperature in the winter, or other factors unfavorable to the maturing of the wood, aggravate the diSBculty. The bursting of the bark is probably caused by the freezing and thawing of the tissues under these unfavorable conditions. Both troubles are more injuri- ous to trees with exposed trunks. A low-headed and spreading top, soils not too rich, and cultural methods which favor the early maturity of the wood, lessen the danger. The trunks may also be protected by a board, matting, or screen of som
