 surveys of Oscar B. Walsh, C. E., and have been prepared for re- 

 production by Harold E. MacEwen. Based upon our excavation data,

 Harvard, executed four drawings depicting Pueblo Bonito as it prob- 

 ably appeared in its heyday. Except as noted, other illustrations 

 herein are from National Geographic Society photographs by O. C. 

 Havens, of Gallup, N. Mex. Mrs. Jeraldine M. Whitmore, of the 

 National Museum, has typed the final manuscript.

 necessary draftsmanship and clerical assistance. And, finally, to the
