Most of the limbs have been killed, although the withered leaves may remain on them for some time afterward, and the bark may show few external symptoms of the disease.

Any burs produced are dwarfed, but there is no evidence to prove that nuts from them are poisonous. (Figure 4.) trunk, or on the branches (figs. 2,3, and 4). Sprouts may appear below CA'cry canker on a tree, and there are often man}' such cankers. These sprouts are usually very luxuriant and quick grow- ing, but rarely survive their third year, as they in turn are killed by the fungus. The age of the oldest sprout, as determined by the number of its annual rings, is an indication of the minimum age of the canker immediately above. The annual dcA'clopment of sprouts from the base of a tree has been obscrA^cd to continue for at least seven years after the dcatli of tlic tree. If infection of these basal sprouts could be x)re- vcnted, they would develop into a much better tyi^c of coi)picc than is usually seen, since they arc well rooted in the ground. After the tree is dead the dead sprouts on the trtuil':, together with the scars left by cankers on the outer layers of wood, serve to show what killed the tree long after the bark has completely decayed and fallen away. The wood is not materialh^ injured, and may be used for all timber pur- poses for which healthy trees might be used, provided the diseased trees do not stand so long after they are dead that they l:iccomc sap-rotted and check- ed. This fact greatly facilitates the prompt dcstrttction of diseased trees, which will do much to cheek the rapid spread of the disease, and in localities where such work is organized under State coiitrol, as in \'irginia and West Virginia, may limit it entirely.
