 Honorable J. W. PoWELL,

Sir: Complying with your order directing lue to proceed to Flor- 

 ence, Arizona, to witness the closing up of the work under contract for 

 the preservation of Casa (Irande rnin near that place, and to report to 

 you the amount and character of the work accomplished, certifying the 

 amount due the contractors under each item, I have the honor to 

 submit the following report:

 location of the ruin is filed herewith, marked Exhibit A. and made a

 these measurements, was submitted to me in writing. It is filed here-
