ADMINISTRATIVE REPORT XLII 
before now, save that through the exigencies of Congressional 
action the provision for publication of bulletins is temporarily 
suspended. 
During the two months, Dr Thomas continued the revision 
of the monograph on ‘Indian Land Cessions,” by C. C. Royce, 
and made substantial progress in the preparation of an intro- 
duction to the work. It is the purpose so to arrange this 
monograph that it will become a standard work of reference 
concerning the land cessions between the Indians and the 
Federal Government. In this respect the monograph was 
substantially complete when it left the hands of the compiler, 
Mr C. C. Royce, but it has been thought desirable to incorpo- 
rate an introductory chapter, setting forth as fully as practicable 
the colonial land treaties with the Indians, as well as the general 
policy of treating with the aborigines throughout the history 
of our country in both colonial and post-Revolutionary times; 
and to render the exposition still more comprehensive, the 
policies of the Spanish and French governments with respect 
to Indian rights and treaties in the territory now belonging to 
the United States are discussed, illustrated by typical laws 
and treaties, and summarized. The preparation of the intro- 
duction has required extended research among early records 
and publications. The work is now well advanced. 
Work in archeology—During February and March Mr Cosmos 
Mindeleff continued the preparation of a report on the “Cliff 
Ruins of Canyon de Chelly, Arizona.” A preliminary draft 
of the text was brought to substantial completion, and the later 
portion of March was spent chiefly in the preparation of illus- 
trations. This report, representing the results of some fifteen 
months continued field work, will unquestionably form a rich 
contribution to the knowledge of southwestern archeology. 
As indicated by the text and illustrations already completed, 
the surveys were conducted with great detail, and a large 
body of facts pertaining to the rapidly disappearing works of 
the prehistoric peoples of this region has been put together in 
a systematic way. It is thought that these surveys and the 
reports based thereon will render Canyon de Chelly classic 
ground for the archeologist.
