Mount Hayden, or tbe Great Teton, was measured by triangulation 

 with the gradieuter. Three different triangulations 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 fe^t.
