TOZZER] EXCAVATION AT SANTIAGO AHUITZOTLA, MEXICO 17 



Section i-j also runs north and south. An attempt is made here 

 to indicate the character of the stratification as shown by the various 

 excavations. Althoug;h not inckided in the section, the floor of 

 Room I together with the entrance to Tunnel /, Floor P, and Tunnel 

 j are shown. 



Section k-l rung east and Avest. Attention should be called here to 

 the earth and stones left to the east of the Eastern Terrace. This is 

 not shoAvn in any of the other plans. 



In the description of the site few measurements will be given, as 

 these are clearly inthcated on the plans and sections. 



Order and method of excavation. — A small excavation had been 

 made in the center of the hill by some one hunting for idolos. This 

 had, unfortunately, destroyed a large portion of the southern part of 

 the topmost floor (A) and made it impossible to obtain complete data 

 on the site. Several pieces of the plaster of the floor Avere found. 

 A second and more excusable damage was done to the hill by the cut- 

 ting of a road along the northern side. This decreased the whole 

 area possible for excavation by about a fourth and made it impossible 

 to establish the complete plan of the northern side. With these two 

 exceptions the hill was intact. 



Higher foors. — The excavation started about the center of the hill 

 to the north of the hole made by the relic hunter. Floor A was imme- 

 diately discovered (pL 8, a) under a thin layer of adobe. The floor 

 was only about 0.6 m. from the surface. Floor A was followed in all 

 directions. On the northern and western edges of this floor excava- 

 tions were made and Room I (pi. 4, h) with its fine plaster floor was 

 uncovered. The greater part of Room I was found filled in solid to 

 within 0.4 m. of the level of the hill with adobe bricks. This adobe 

 filling extended to the east into the space I have called the Patio, 

 over Floor P to the point where the stone wall makes a corner and 

 turns to the south (near 4, pi. 1). Room I was excavated its entire 

 length, showing the pillars at either end. Through the doorway on 

 the west. Room II (pi. 8, c) was entered. To the west of this entrance 

 and at several places in Room II the filling w^as made of alternate 

 layers of earth and stones. Working from Floor A, Rooms V 

 and VI (pi. 5, &) were soon shown. Excavation was also carried on 

 to the south of Floor A in the old depression made at some previous 

 time and continued until Floor P was encountered. Work was con- 

 tinued to the south until the northern wall of Rooms III and IV 

 was found. This cleared the space of the Patio down to the level of 

 Floor P. Rooms III and IV were next uncovered. By continuing 

 east of Room IV a portion of the Eastern Terrace w as shown. The 

 terrace was followed from this point in both directions and the south- 

 eastern corner was soon found (pi. 5, a). The corresponding north-
