Triangulation from Haiku to Kaupo. 
The geodetic connection between the two latitude stations 
was made by two series of triangles. The first passes over 
the summit, the second is carried around the west flank of 
the mountain and reaches Ka Lae o Ka Ilio (Kaupo) through 
a chain of 15 triangles. The first series is more direct, con¬ 
taining only 7 triangles. The agreement between the two 
independently calculated positions of Kaupo leaves no doubt 
as to the accuracy of its position. 
Plate 9 shows the location of the trigonometrical points. 
The following table gives the angles, distances, and lati¬ 
tudes :
