Abstract

Up to within the past eight or ten years, very little attention had been paid in America to the study of those forms of fungi causing forest diseases. The reasons are obvious. Previously, the occurrence of a few diseased trees was practically unnoticed, due to the vast area of our forests. But, with the advance of the lumberman in the last decade, the situation has changed, and a demand has arisen among all classes of people for a more economical and rational treatment of the existing forest lands. The diseased trees of the primeval forest were ignored as they were so few in comparison with the sound ones. While now the marked appreciation in the value of timber, cause the timber destroying agencies to become of immediate interest. These silent enemies of the forest are working here and there, not attracting the attention of the casual observer as do the careless habits of the lumberman and the forest fires.
