The length of time required for logging injuries to effect serious losses . 7 / 2. A quantitative measure of the fixed and cumulative losses— re- sulting from the cull and degrade associated with logging injuries The relative susceptibility of different kinds and sizes of wounds to the development of decay and discoloration. The fungi that are primarily responsible for the defects develop- ing at logging injuries, and their relation to the chief types of decay .®/ 5. The correlation of external characteristics of wounds with kinds of fungi that become established and with the rate of decay (9, 15), which could be used as a guide for forest managers in evalu- ating "risk trees" in reserve stands. 7/ Fixed loss refers to damage that remains static and lowers the lumber grade, such as ingrown bark. Cumulative loss, as used by Meinecke (14), includes both the present amount of rot and the decay volume that accumulates over a given period of years. 8/ This phase of the study is largely omitted from this paper and will be presented as a separate publication. 5.
