Emory — An Archaeological Sitri'cy of Holcakala 247 



three platforms, which are situated respectively in the south, east, 

 and north parts of the valley, are notable for the volcanic bombs 

 used in construction. The isolated south platform is bordered by 

 a wall less than 2 feet high, which forms a rectangle 15 by 7 

 feet. The space within the walls is tilled with sand and gravel 

 forming a surface which corresponds with the slope of the ground. 



The poorly preserved east platform with dimensions about 

 12 by 4 feet is similarly constructed. The north platform (PI. 

 XXIII, A ) differs from the other two in the presence of a second- 

 ary wall about 5 feet from the outer south wall, which divides 

 the platform into two longitudinal sections. Due west of the north 

 platform is an anomalous structure consisting of two walls forming 

 a right angle that corresponds in position with the southwest 

 corner of the platform. Near the entrance to Hanakuhi Valley 

 are two solidly built ahus constructed of unmarked local stones. 

 The north ahu measures 5 by 7 feet and the south ahu 5/4 by 9 

 feet ; both are 2^ feet high and lie east and west. By standing 

 on them the three platforms in the valley can be seen and the 

 approach to the valley watched. 



W'^e removed all the rocks of the south ahu and dug under 

 it, discovering nothing. Excavation of north platform (PI. XXIII, 

 A) resulted only in a knowledge of its construction. A wall 

 extending north and south for 19 feet along the Puu Kumu slope 

 of the valley had been built up 2 feet. Then the side towards 

 the slope had been filled in with two layers of stone, half as large 

 as those in the walls, and then coated over with several layers of 

 sand. This made a terrace 5 feet wide, closed at either end 

 by a solidly built wall. At the back of this terrace was laid a 

 single course of volcanic bombs, averaging a foot and a half in 

 diameter, and 3 feet back from this line was laid another row 

 of bombs. The shallow space between was filled level with sand 

 3 inches deep on the up valley side, and 12 inches deep on the 

 down side. The terraced platform rests on hard-packed cinders in 

 which bombs and pieces of lava are embedded. The south plat- 

 form rests on a flat solid lava floor and is similarly constructed.
