468 GEOLOGY OF THE DENVER BASIN. 



having 1,044 more or less complete fragments of plants. There were 118 

 species, of which number 28 were regarded as new to science and 32 as 

 new to the Laramie flora so called. 



The collection upon which, in large part, the present chapter is based 

 was also made by Rev. Arthur Lakes for and under the direction of Mr. 

 S. F. Emmons. It is without doubt the largest collection ever made of the 

 Golden plants. 



Besides the collections above enumerated, smaller ones have been made 

 by Prof. Lester F. Ward 1 for the United States Geological Survey, by Rev- 

 A. Lakes for Princeton College, New Jersey; by Mr. George Haddon for 

 Mr. R. D. Lacoe at Coal Creek, and by Mr. R. C. Hills, or his assistants, 

 for Columbia College, New York. These have all been placed at my dis- 

 posal and made use of in this connection. 



To return to the Dakota group plants. These were found in abun- 

 dance by Lieut. H. C. Beckwith, U. S. N., and Rev. A. Lakes, at Morrison, 

 Colo. The exact date at which they were collected does not appear, but 

 they were first described by Professor Lesquereux in 1883. 2 The entire 

 collection is now in the United States National Museum, having been 

 donated after the death of Lieutenant Beckwith.
