The most interesting discovery of the entire season consisted in locating two series of large geometric earthworks on the eastern side of the Everglades, not far from Indian town. One of these groups is one of the largest and best preserved works of this type now existing on the North American continent. It is hoped that at an early date the bureau will be able to begin excavations on this most interesting site. At the completion of this reconnaissance, Mr. Stirling returned to Washington, leaving almost immediately for Chicago in order to attend a meeting of the National Research Council, the purpose of which was to organize research on the subject of early man in America. Dr. John R. Swanton, ethnologist, was engaged in field work in Louisiana from July 1 to August 14, 1930. It was found that Rosa Pierrette, the sole Indian acquainted with the Ofo language and the one from whom, in 1908, he obtained the only specimens of that language in existence, was dead, and the language therefore is dead also. A search was made for speakers of Atakapa, but all appeared to be gone except one old woman who could barely recall a few words. The Chitimacha Indians of Charenton were visited and a small amount of linguistic material was obtained from them. Of the Tunica at Marksville, only two or three are still able to use the old tongue, but one of these proved to be an ideal informant and Doctor Swanton obtained from him a number of short stories and one long story in native text. The rest of the time was spent at Kinder, where a considerable body of material in Koasati was obtained. In view of the extinction of Atakapa as a spoken language, Doctor Swanton considered that the words, phrases, and text collected by Dr. A. S. Gatschet in 1886, which comprise by far the greater portion of the material in that tongue still preserved, should be published without delay and the greater part of the winter of 1930-31 was spent in editing it. To Gatschet’s material have been added the Eastern Atakapa words collected by Murray and the Akokisa vocabulary obtained by the French captain, Bérenger, and published by Du Terrage and Rivet. A bulletin containing all this is now in the hands of the printer. Work has progressed on the tribal map of North America which is being copied by Mrs. E. C. M. Payne, and additions have been made to the text to accompany it. Doctor Swanton is preparing the first draft of a Handbook of the Indians of the Southeast. The closing weeks of the year were devoted to reading the proof of Bulletin 103, entitled “Source Material for the Social and Ceremonial Life of the Choctaw Indians.”
