192 THE REPORT OF THE No. 16 In the treatment of Stag Head, the sod should be removed from a space two or three feet in radius about the tree. This circular area should be frequently stirred by the spade and kept raked, as this process will tend to promote aeration; but unless provision has been made for proper drainage when the tree is planted, aeration will be perceptibly checked whenever i prolonged wet period occurs. The young rootlets decay, the tree is weakened, and becomes more liable to attacks of fungi, which prey upon the roots. (3). Another cause for the death of many trees in Sun Scald, which produces a wilting of ihe tissues by a too rapid evaporation from the leaves. The tender young shoots are very liable to injury from such a source, especially if they are subjected to a hot sun after a period £>f rapid growth in moist weather. The edges of the leaves turn reddi-jh yellow, wilt and dry tip.

The tissues wilt, owing to too rapid evaporation during fine, warm days in winter, when the soil about the roots is frozen, or when drj oold winds prevail. It is very difficult to provide remedial treatment for Sun Scald and Winter Blight. Per- haps a liberal mulching with manure or straw would be as efficacious a remedy as any that could be devised. (5). Other causes occasionally produce serious results but only under peculiar circum- stances. Sometimes the air of cities and towns becomes poisoned with harmful gases to such an extent that whole avenues of trees are seriously affected. There is of course no remedy available in such a case.
