 were taken from the side of a trench dug in the forest floor. In 

 several instances an area was sampled more than once. The 16 

 samples of surface soil from fields and thickets were taken from 

 four areas. Surface debris was sampled three times near the

 right and lower left) with three samples each gave six of the 

 positive samples from under old stumps and from decayed-out 

 root systems; another site in two samples gave one positive and

 (pi. 2) resulted in nine of the positive samples taken under loose 

 bark of standing dead stubs and trees. Another stub gave one
