 and sixty feet distant from the south side of it. 

 Fifty feet of the new dam ran north and south, 

 parallel to the old one; then, forming a right 

 angle, it extended thirty-five feet toward the east. 

 It averaged three feet in height, being made al- 

 most entirely of large chunks, dead-tree cuttings 

 from six to fifteen inches in diameter and from

 windrow of dead-timber wreckage. 



The day it was completed the builders shifted 

 the scene of activity to the brook, a short dis- 

 tance below the point where it emerged from the
