18 BUREAU OF AMERICAN ETHNOLOGY 
During the year uniform rules and regulations intended to 
serve in carrying out the recently enacted law for the preser- 
vation of national antiquities were formulated and adopted 
by the three departments having control of the public 
domain. Under these, on recommendation of the Secretary 
of the Smithsonian Institution, permits were issued for con- 
ducting explorations on Indian reservations and in national 
forests in Idaho and Wyoming, by the American Museum of 
Natural History, New York, and among the ancient ruins on 
the public lands in Navajo and Apache Counties, Arizona, by 
the University of California. Arrangements were also made 
with the Interior Department for carrying on explorations 
at Casa Grande Ruin, Arizona, by the Smithsonian Institu- 
tion. Under the same law during the year three important 
archeologic sites were declared national monuments by the 
President of the United States. They are as follows: 
Chaco Canyon, in New Mexico, including several important 
ruined pueblos; El Morro, New Mexico, commonly known as 
Inscription Rock; and Montezuma Castle, in Arizona, an 
important cliff-ruin. 
CATALOGUE OF LINGUISTIC MANUSCRIPTS 
The archives of the Bureau contain 1,626 manuscripts, 
mainly linguistic, of which only a partial catalogue had 
previously been made. In January Mr. J. B. Clayton, head 
clerk, began the preparation of a card catalogue, which was 
completed at the close of the year. The manuscripts were 
jacketed in manila envelopes of uniform size, except where 
bulk prevented, and were numbered from 1 to 1,626. 
The catalogue comprises about 14,000 cards which give, 
as completely as available data permit, the names of stock, 
language, dialect, collector, and locality, as well as the date 
of the manuscript. It was not possible in every instance to 
supply all the information called for under these heads, but 
the. card has been made as complete in each case as the 
‘information permitted. The cards have been arranged in 
one alphabetical series, the names of the languages not only 
under these languages in their proper alphabetic place, but
