From this it will be observed that, taking the rate of compensation provided for in the contract as a basis, the contractors have performed work in excess of that authorized to the amount of $638 [$637].  They are fully advised that there is no provision for the payment of this excess.  The requirements of the contract are, in my opinion, fully met in the quality of material used and the work performed.

The preservation of the ruin is incomplete.  There are six places where lintels have disappeared and not been replaced and a corresponding number of cavities that should be filled.  Deep seams have been cut in the walls by the action of the elements, and unless far greater provision is made for its protection the work already done will be of small avail.

At many places where the debris came in contact with the wall disintegration seems to have resulted.  At a slight touch it frequently crumbles.  Owing to this fact two sections of the wall fell during the progress of the work when the debris was removed—­one from the east wall, described above, and one from the south wall near the west extremity.  These breaches maybe observed as shown in two of the six accompanying photographs [plates CXX, CXXI].  These photographs were taken ten days before the work was completed.  There being no professional photographer in that vicinity I was compelled to take advantage of the kind offer of Mr H. H. Burrell, an amateur photographer, who happened to be there at that time.  Thus the views I secured failed to show all the brickwork done.  The coating of mortar was not applied until after the date on which the views were taken, in consequence of which the bare bricks are shown in the views.

During the progress of work in removing the debris a number of articles of interest to the ethnologist were found at various depths and localities.  They have been packed by the contractors and will be sent to the National Museum.

The floors in the center, north, and east rooms were found to be about 8 feet above the ground surface.  The material was similar to that of which the walls are composed.  The west and south rooms appeared to have had floors at one time on
