LETTER OF TRANSMITTAL 



Department of the Interior, 

 United States Geological Survey, 



Washington, D. C, August 3, 1903. 

 Sir: I have the honor to transmit herewith a manuscript by Mr. F. C. Schrader, 

 entitled "A Reconnaissance in Northern Alaska in 1901," and to recommend its pub- 

 lication as a professional paper. 



This report is based on an exploration made by Messrs. W. J. Peters and F. C. 

 Schrader from Yukon River to the Arctic Ocean during the winter and summer 

 of 1901. Besides important geographic results, the investigation is the first to 

 throw light on the complex geology of the Rocky Mountain system of northern 

 Alaska. Mr. Peters, leader and topographer of the expedition, has contributed 

 notes on itinerary, topographic methods, and climate. 

 Very respectfully, 



Alfred H. Brooks, 

 Geologist in Charge Division Alaskan Mineral Resources. 

 Hon. Charles D. Walcott, 



Director of United States Geological Survey.
