Before entering upon a description of the villages and ruins, a few words as to the preparation of the plans accompanying this paper will not be amiss. The methods pursued in making the surveys of the inhabited pueblos were essentially the same throughout. The outer wall of each separate cluster was run with a compass and a tape measure, the lines being closed and checked upon the corner from which the beginning was made, so that the plan of each group stands alone, and no accumulation of error is possible. The stretched tapeline afforded a basis for estimating any deviations from a straight line which the wall presented, and as each sight was plotted on the spot these deviations are all recorded on the plan, and afford an indication of the degree of accuracy with which the building was carried out. Upon the basis thus obtained, the outlines of the second stories were drawn by the aid of measurements from the numerous jogs and angles; the same process being repeated for each of the succeeding stories. The plan at this stage recorded all the stories in outline. The various houses and clusters were connected by compass sights and by measurements. A tracing of the outline plan was then made, on which the stories were distinguished by lines of different colors, and upon this tracing were recorded all the vertical measurements. These were generally taken at every corner, although in a long wall it was customary to make additional measurements at intervening points. [Illustration: Plate XVII. View of Hano.] Upon the original outline were then drawn all such details as coping stones, chimneys, trapdoors, etc., the tapeline being used where necessary to establish positions. The forms of the chimneys as well as their position and size were also indicated on this drawing, which was finally tinted to distinguish the different terraces. Upon this colored sheet were located all openings. These were numbered, and at the same time described in a notebook, in which were also recorded the necessary vertical measurements, such as their height and elevation above the ground. In the same notebook the openings were also fully described. The ladders were located upon the same sheet, and were consecutively lettered and described in the notebook. This description furnishes a record of the ladder, its projection above the coping, if any, the difference in the length of its poles, the character of the tiepiece, etc. Altogether these notebooks furnish a mass of statistical data which has been of great service in the elaboration of this report and in the preparation of models. Finally, a level was carried over the whole village, and the height of each corner and jog above an assumed base was determined. A reduced tracing was then made of the plan as a basis for sketching in such details of topography, etc., as it was thought advisable to preserve.
