Field Columbian Museum — Reports, Vol. II. 



ming and collected full suites of specimens illustrating the occurrence 

 of that mineral, as well as other ores and minerals of the vicinity. 

 A find in North Dakota of Cretaceous bird remains and other verte- 

 brates, news of which had reached the Museum, was investigated by- 

 Mr. Riggs, Assistant Curator of Paleontology. About two weeks 

 were spent in the region, and as a result some fragmentary fossils 

 and economic specimens were secured and arrangements made to 

 have further finds forwarded to the Museum. The Curator spent 

 about two weeks in mineral localities in Oxford County, Maine, and 

 obtained about two hundred specimens of the typical minerals of the 

 region, such as beryl, orthoclase, tourmaline, bertrandite, lepidolite, 

 quartz, garet and amblygonite. Some collecting of local fossils and 

 minerals at Thornton and Elmhurst, 111., was carried on by the 

 Curator and Mr. A. W. Slocom. 



The collection of an adequate representation of the forest trees 

 of the United States that bear particularly upon commerce and the 

 deforestation of the country that was begun several years ago and 

 lapsed for the last three years on account of lack of time with the 

 then working force of the Department of Botany, has again been taken 

 up, three weeks being spent in Northern Minnesota for this purpose. 

 Incidental to this work, other collections of economic material were 

 made in the same locality. The Department has continued its field 

 work upon the Plant Life of the "Lake Chicago Basin," a flora that 

 is rapidly becoming extinct from drainage and reclaiming of the area 

 for building and other purposes. During the year 388 specimens 

 have been added to the already fine series representing this interest- 

 ing region. 



The expeditions of the Department of Anthropology include 

 three by the Curator to Oklahoma and New Mexico, one of these 

 being especially to the Pawnee, funds for which were generously pro- 

 vided by Mr. Cyrus H. McCormick, Mr. Martin A. Ryerson, Mr. Wat- 

 son F. Blair and Mr. E. E. Ayer; two by Assistant Curator Simms to 

 the Crows; Mr. Mooney's work especially concerning the heraldry of 

 the Cheyenne; Mr. Hudson's extended investigations among the tribes 

 of California; Mr. Newcombe's investigations among the Haidas, 

 especially concerning certain phases of their mental culture. There 

 remains to be noticed the continuation of a series of investigations 

 begun three years ago by the Department among the Hopi, and 

 which have been carried on through the generosity of Mr. Stanley 

 McCormick. The work during the present year has been in charge 

 of Mr. H. R. Voth, who is engaged in preparing for publication 

 accounts of Hopi ceremonies. Mr. McCormick's provision also makes 

 possible the completion of the series of Oraibi altars.
