language. This discovery will necessarily delay the publi- 
cation of the Natchez material already referred to, but if 
prompt measures are taken, will insure the preservation of 
that language in its completeness. At Eufaula (Creek Nation) 
he made a slight investigation into the social organization 
of the Creeks—enough to determine that much work still 
remains to be done in that tribe entirely apart from language. 
Doctor Swanton returned to the office June 7, and during 
the remainder of the year was engaged in arranging and 
collating the material collected by him. 
Dr. J. Walter Fewkes, ethnologist, was employed in the 
office during the first month of the year reading proofs of 
his articles on the Aborigines of Porto Rico and Neighboring 
Islands and on Antiquities of Eastern Mexico, for the Twenty- 
fifth Annual Report of the Bureau. Part of August and all 
of September were devoted to the preparation of a bulletin 
on the Antiquities of the Little Colorado. He spent seven 
months in Arizona, leaving Washington on October 15 and 
returning the middle of May. During four months he super- 
intended the work of excavation, repair, and preservation of 
the Casa Grande Ruin, in Pinal County, Arizona, and in 
March and April visited a number of little-known and unde- 
scribed ruins along Canyon Diablo and Grapevine Canyon, 
gathering material for his bulletin on The Antiquities of the 
Little Colorado Valley. During May and June he was em- 
ployed in the office, devoting his time to the preparation of 
an account of the excavations at Casa Grande. The explo- 
rations at Casa Grande were conducted under a special 
appropriation disbursed directly by the Smithsonian Insti- 
tution, and Doctor Fewkes's preliminary report has been 
submitted to the Secretary. It is anticipated that a final 
report on the work when completed will be published by the 
Bureau of American Ethnology. 
Mr. J. N. B. Hewitt was occupied during the earlier months 
of the year in preparing and correcting matter for the Hand- 
book of American Indians, devoting special attention to the 
articles on the Iroquoian family, Iroquois, Mohawk, Montour, 
Mythology, Nanabozho, Neutrals, Oneida, Onondaga, and
