explorations and surveys in the department of the missouri. 



Headquarters Department of the Missouri, 



Office of the Chief Engineer, 

 Fort Leavenworth^ Kans., July 22, 1878. 



Sir : In rendering yon my annual report for the fiscal year ending 

 June 30, 1878, I regret to say that the operations of the office have been 

 very meager. There being but a small sum at my disposal, no oppor- 

 tunity has arisen to conduct surveys, and beyond the routine calls upon 

 the draughtsmen no maps have been prepared. 



An edition of sheet No. 2, Department of the Missouri, revised and 

 corrected to date, was engraved and issued last fall. 



The total mileage of journals of inarches and scouts recorded in this 

 office for the calendar year 1877 was 7,214 ; and the mileage of recon- 

 naissance in the southwest of Colorado, conducted by Lieut. C. A. H. 

 McCauley, my assistant, was 2,030 miles. 



The report of Lieutenant McCauley, herewith submitted, illustrates 

 what may be done by the indefatigable energy and untiring industry of 

 one man. The results of his observations are given in a shape which 

 presents the present condition of that section of country in a manner 

 which will be of interest to all connected with it. Great credit should 

 be given to Lieutenant McCauley for his systematic collection of notes 

 and carefully prepared report, and it is suggested that a large edition of 

 it be prepared separately for distribution to the many who are seeking 

 information of this section. 



A second report on lines of communication between Colorado and 

 New Mexico, in which much of Lieutenant McCauley's notes were used, 

 was submitted to the department commander on January 11, 1878, and 

 was printed March 9, 1878, as Ex. Doc. No. 66, House of Representa- 

 tives, Forty-fifth Congress, second session. This report covers 38 pages 

 of print and is accompanied by three maps. In accordance with its 

 recommendations an appropriation was made by Congress of $5,000, to 

 commence the roads required. This amount will not complete what was 

 desired, as the estimates called for $24,000. 



I have employed my spare time during the year in the compilation of 

 a work which has been thought necessary, and of which the title-page 

 and table of contents are herewith submitted. The manuscript of this 

 work is now in the hands of the Chief of Engineers. 



All of which is respectfully submitted. 



E. H. EUFFNER, 



First Lieutenant of Engineers. 

 The Chief of Engineers, U. S. A.
