It should be added that neither the Director nor any of the collaborators in the Bureau of American Ethnology have visited Casa Grande ruin for some three years, and accordingly that there are no data in this office to indicate whether there is especially urgent necessity for undertaking preservative work at this time; but much confidence is placed in the judgment of the custodian, Reverend Isaac T. Whittemore, who is known to several collaborators in the Bureau.
The subject of the preservation of Casa Grande, in many respects the most noteworthy ruin in the United States, is deemed important; and if the Secretary of the Interior desires more specific information concerning the present condition of the ruin, as a basis for further action or judgment, it will be a pleasure to have an officer of this Bureau make a special examination of, and report on, the ruin during the autumn.
I have the honor to be, yours, with great respect,
W J McGee, Acting Director.
The Secretary of the Interior.
