It would have been desirable to have had a supervisor of the work, but as the contract consumed practically all of the amount appropriated no provision could be made for one. It is fortunate, therefore, that the Reverend I. T. Whittemore, who had in the meantime been appointed honorary custodian of the ruin, generously undertook to look after the work without compensation, and on its conclusion the small sum remaining ($15) was turned over to him, thus exhausting the appropriation. In the sundry civil appropriation act for the year ending June 30, 1893, provision was made for a salaried custodian of the ruin, and Mr Whittemore was appointed to this position. Similar provision has been continued from year to year to the present time. It is to be regretted that the necessities of the case, imposed by the limited amount appropriated, compelled the fixing of a maximum amount of work so far below the amount necessary that the repair of the ruin is incomplete. Had it been possible to carry out the plans, it is believed that the ruin would have stood unchanged for many decades, if not for a century. Should further provision be made for the continuation of the work, it should include an item for the fencing of the area covered by the ruins or of the reservation, and possibly an item for the construction of a roof. It is not clear that a roof is absolutely necessary, but it is certain that it would be very undesirable. The region where this rain occurs has probably less rainfall than any other part of the United States, but it must not be forgotten that while rainstorms are infrequent they are sometimes violent, and what damage they do may be done in a few hours. All the items for the repair of the ruin, except that pertaining to a roof, were so devised that the ruin was not materially disfigured or changed, and were they fully carried out the ruin would present much the same general appearance as before. It is important that this appearance should be preserved as far as possible, but it can not be maintained if a roof is erected over the walls. As four years have elapsed since the completion of the work, it should be possible now to determine whether atmospheric erosion has played a material part in the work of destruction.[1] [Footnote 1: See the letter of the Director of the Bureau of American Ethnology to the Secretary of the Interior regarding the examination of Casa Grande by Mr W J McGee in the supplement to the present paper.] In the original plans and in the specifications which formed part of the contract (although this section was not operative) a plan for a roof was included. Such a structure, if erected at all, should be made as inconspicuous as possible and should be supported entirely from within the building. The system of framing employed might safely be left to the contractor if he were made responsible for the strength of the completed structure. RESERVATION OF THE LAND
