The ground plan of the church shows that the openings were splayed in the thickness of the walls, at an angle of about 45°. In the doorway, in the east end of the building, the greater width of the opening is on the inside, a rather unusual arrangement; in the window, on the north side, this arrangement is reversed, the splay being outward. On the south side are indications of a similar opening, but at the present time the wall is so broken out that no well defined jamb can be traced, and it is impossible to determine whether the splayed opening was used or not. The stones of the masonry are laid with extreme care at the angles and in the faces of these splays, producing a highly finished effect. The position of the beam-holes on the inner face of the wall suggests that the floor of the church had been raised somewhat above the ground, and that there may have been a cellar-like space under it. No beams are now found, however, and no remains of wood are seen in the “altar” end of the church. At the present time there are low partitions dividing the inclosed area into six rooms or cells. The Indians state that these were built at a late date to convert the church into a defense against the hostile Apache from the south. These partitions apparently formed no part of the original design, yet it is difficult to see how they could have served as a defense, unless they were intended to be roofed over and thus converted into completely inclosed rooms. A stone of somewhat larger size than usual has been built into the south wall of the church. Upon its surface some native artist has engraved a rudely drawn mask. [Illustration: Plate XXXVII.
