Sir : You are hereby detailed to visit the St. Elias range of Alaska for 

 work of exploration, under the joint auspices of the National Geographic 

 Society and the United States Geological Surv^ey. The Geological Survey 

 furnishes instruments and contributes the sum of $1,000 towards the ex-

 from the appropriation for the fiscal year ending June 30, 1890, and the 

 manner of its expenditure must conform to that fact. 



The Survey expects that you will give special attention to glaciers, to 

 their distribution, to the associated topographic types, to indications of 

 the former extent of glaciation, and to types of subaerial sculpture under 

 special conditions of erosion, and that you will also bring back informa- 

 tion with reference to the age of the formations seen and the type of 

 structure of the range. 



With the aid of Mr. Kerr, it is expected that you will secure definite 

 geographic information as to the belt of country traversed by you. 

 Very respectfully, G. K. Gilbert, 



Chief Geologist.
