REPORT OF WILLIAM. H. HOLMES. 



LETTEE OF TEANSMITTAL. 



"WASHlNaTON, March 1, 1878. 

 Sir: I submit herewith my report on the ruins of Southwestern Colo- 

 rado for the years 1875 and 1876. A preliminary report on the investi- 

 gations made in 1875 has already been published in the second volume 

 of the Survey bulletins. As the edition of this publication was very 

 limited, it has been thought best to republish that report with correc- 

 tions and additions, in connection with the report for 1876. 

 Very respectfully, your obedient servant, 



WM. H. HOLMES. 

 Dr. r. V. Hatden, 



United States Geologist in charge.
