IV REPORT OF THE CHIEF OF ENGINEERS. 



An edition of map No. 2, Department of the Missouri, revised and cor- 

 rected to date, was issued last fall. Lieutenant Kuifner submitted a 

 second report on lines of communication between Colorado and New 

 Mexico, which was printed as Ex. Doc. No. 66, House of Eepresenta- 

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

 of print, and is accompanied by three maps. 



Lieutenant Euffner has employed his spare time during the year in 

 preparing a compilation or descriptive index of the reports of the Corps 

 of Engineers for the ten years 1866-1876, entitled "A Eecord of Ten 

 Years of Engineering by the Corps of Engineers, U. S. A." The manu- 

 script is now completed.
