Mount Hay den, or tlie. Great Teton, was measured by triangulation 



with the gradienter. Three diflfereut trianguUitions were made to it 

 from different points, the elevations of the bases above the sea being 

 determined by barometric observations. The several results of the tri- 

 angulations are as follows : 13,858 feet, 13,705 feet, 13,889 feet.
