was based on the fact that the antecedent hypothesis presented prob- 

 lems which no one had been able to solve. Probably also Emmons 

 suspected that the late Tertiary sediments had formerly overlapped 

 the Uinta Mountains. E. W. Shaw raised the query whether the 

 present elevated position of the Browns Park beds in certain places 

 might not be due to subsequent deformation. Hancock gave reasons 

 for doubting this. B. S. Butler spoke of a remnant of a mature 

 topographic form on the north side of the Uinta Mountains in the 

 'form of a gravel-capped plateau. A similar form occurs on the south 

 side of the range and one is impressed with the probability that at 

 one time they were connected and are parts of a mature topography 

 now dissected, and that a correlation can be made between the physio- 

 graphic stages represented in the Uinta region and those of the High 

 Plateau. C. J. Hares drew an analogy with the North Platte and 

 Sweetwater River systems and thought their history was similar to that 

 described by Hancock for the Green River- Yampa system. 



G. F. LouGHLiN, Stratigraphy of the Tintic Mining District, Utah. 

 The sedimentary rocks of the Tintic district have a total thickness 

 of more than 13,000 feet, the lower half consisting of quartzite with 

 a narrow shale band at its top and the upper half consisting chiefly of 

 limestone and dolomite. These rocks were first described in 1897 by 

 Tower and G. Otis Smith, who assigned the quartzite and shale to the 

 Cambrian, and the limestone-dolomite series tentatively to the Car- 

 boniferous. In 1905 Weeks found Middle and Upper Cambrian 

 fossils in the lower 2000 feet of limestone. During a recent resurvey 

 of the district by the U. S. Geological Survey the overlying limestones 

 were found to include 2000 feet or more of Ordovician, 150 or more of 

 Devonian, and a minimum of 1800 feet of lower and upper Mississip- 

 pian. Two unconformities were recognized; one at or near the base 

 of the Ordovician, and one at the base of the Mississippian. No proof 

 of an unconformity in the Cambrian quartzite corresponding to that 

 in the Big Cottonwood Canyon section could be found. The Middle 

 Cambrian limestones are only about one-third as thick as those in the 

 House Range and Blacksmith Fork sections, but no evidence indicating 

 the cause of this difference was found.

THE ANTHROPOLOGICAL SOCIETY OF WASHINGTON 



At a special meeting of the Society held November 3, 1914, at the 

 Public Library, Dr. J. Walter Fewkes, of the Bureau of American 

 Ethnology, read a paper on Vanished races of the Caribbean, using lan- 

 tern slides to show characteristic artifacts found on different islands. 

 About 235 persons were present. The lecturer said that while it 

 has been frequently stated that there are races of men without his- 

 tory, by this must be meant that they have no written history; for 

 every race has had a cultural development worthy of study even if
