 Table 1 shows the average loss in weight of six blocks when subjected 

 to the action of the various fungi indicated :

 under the conditions obtaining in this experiment and that the absence 

 of unsound wood in the living tree will probably have to be explained 

 on some other basis than inherent resistance in the wood itself.
