A RUIN UPON A RUIN 



Features of two of the three superposed buildings may be distinguished in this picture. The few 

 courses of faced stone represent the lower portion of the south wall of the most recent structure, while 

 below them, to the right of the shovel, a wall of the cobblestone house runs at an oblique angle beneath 

 the later ruin. Sixteen feet of earth was removed in reaching the floor of the circular chamber in the 

 foreground. Much of the success of an archsological expedition depends upon the interest and devo- 

 tion of one's helpers. For thirty years Bill Ross has worked among the ruins, developing a positive 

 genius for locating specimens in unpromising places
