As one result of the attack of the fungus, the greater number of the buds in the axils of the scales of the infected bud have grown out as twigs, but not into well-developed ones. In consequence, nearly every twig has been killed back by the winter, but not completely, so that from each twig- Ijase has sprung a new crop of stunted immature twigs like the first, and equally liable to be killed in the following winter. Thus has arisen that tangled mass of dead or sickly birch twigs which we call a witches' broom. [Edit.]
