of America. In one canyon in which these excavations were con- 
ducted the cliff dwellings extend along the wall of the canyon for 
about 2 miles, while in another locality in the same general region 
one of the many pueblo ruins covers an area of about 600 feet square. 
Other photographs were presented showing the excavation and re- 
pair of the celebrated Balcony House in southern Colorado, conducted 
under the joint auspices of the Smithsonian Institution and the Colo- 
rado Cliff Dwellers Association. Excavations were made also in 
newly discovered cliff dwellings and other archeological remains in 
northwestern Arizona. 
Field work has been conducted by the Bureau of American Eth- 
nology among the tribes which composed the Creek Confederacy of 
the Southern States; the Tewa Indians of the Rio Grande Valley, 
New Mexico; the Winnebago Indians of Wisconsin and Nebraska; 
the Piegan, Blackfeet, Cheyenne, and Menominee Indians of the 
Algonquian family; the Chippewa Indians, especially with reference 
to their music; the Osage Indians, now in Oklahoma, and the Iro- 
quois in New York. A study of the past and present population of 
the Indians, with the various causes of their decrease, is being con- 
ducted, and a bibliography of the Hawaiian Islands is in prepa- 
ration. 
Resignation of Senator Henderson.—Senator Henderson stated 
that he had served the Institution as a Regent for 19 years, but that 
he had now reluctantly come to the conclusion that it was neces- 
sary to relieve himself of all possible work, as the condition of his 
health would not permit him to continue his duties with satisfaction 
to himself and justice to the Institution. He therefore desired to 
tender his resignation as a Regent to take effect at such time as would 
best suit the board’s convenience. 
After discussion, the Senator first submitted his resignation as a 
member of the executive committee to take effect at once, and on 
motion it was carried— 
That the resignation of the Hon. John B. Henderson, chairman of the execu- 
tive committee, as a member of that committee, be accepted with regret. 
The Senator then presented his resignation as a Regent to take 
effect March 1, 1911. 
Judge Gray offered the following resolution, which was unani- 
mously adopted: a 
Whereas the board of Regents of the Smithsonian Institution having learned 
that the Hon. John B. Henderson has tendered his resignation as a Regent, a 
position he has filled with signal ability for 19 years; 
Resolved, That the Regents desire here to express to him their high apprecia- 
tion of his services as a member of the board, their sincere regret at the termi- 
nation of his official connection with the institution, and their cordial good 
wishes for his future health and happiness.
