Sinecu and Isleta notes are marked, "D7-97" and "D-15," as are corresponding notes in Mooney's notebook, Catalog Number 1953, where these figures apparently refer to the dates December 7 and 15, 1897. See 19th Annual Report, Bureau of American Ethnology for year 1897-98, page xvi, referring to Mooney's trip to this area in December, 1897. --MCB, 1/67.
