FLORA OF THE TRINITY FORMATION. 339 



the greater part of the length of this canj^on and its several branches, as 

 well as farther up on its sides, there are vast quantities of silicified wood, 

 some of it in good condition. Well down in the ravine are some high 

 bluffs giving fine exposures of Trinity sands with clay seams. In one of 

 these there is a dark layer containing obscure vegetable remains, among 

 which a cycadaceous leaf could be made out. From some of these cliffs 

 vertebrate bones may be seen projecting. They were much decayed, but 

 a good collection could probably be made by excavation in the soft sands. 



After further examination of the beds in the valley of the Paluxy, I 

 crossed the divide to the Bosque, which also traverses Trinit}' strata, the 

 Glexa Rose beds capping the hills. This valley was examined from Steph- 

 ensville to Hico, and I returned from the latter place to Granbury by way 

 of Glenrose, having seen all the principal phases of the Trinity formation, 

 and collected such specimens of vegetable nature as they yield. 



Mr. Harvey made a good collection of the plants from the Glen Rose 

 beds in the Paluxy Valley and shipped them in eight boxes to Washington, 

 where they arrived on January 22, 1892. As it was desirable to have a 

 report upon them as early as possible, they were sent to Professor Fontaine 

 at once for determination. In preliminary reports dated January 30 and 

 March 10, 1892, he was able to correlate the flora in its leading aspects 

 with that of the James River beds of the Older Potomac. His final report 

 was rendered in August and was published in the Proceedings of the United 

 States National Museum." The flora as thus made known consisted of 23 

 distinct forms, 7 of which occur in the Potomac formation, 4 in the Weal- 

 den, and 2 in the Urgonian. The 10 new species and varieties were near 

 to species from these formations, especially the Potomac. No dicotyle- 

 dons were found in the Trinity. 



The collections that I made in the Trinity of Arkansas were not sent to 

 Professor Fontaine at the same time as those from the Glen Rose beds of 

 Texas, but on October 28 they were sent him along with a number of 

 other small collections. In a letter from him dated January 23, 1894, he 

 says of these plants : 



The specimens that you sent me from near Murfreesboro, Ai-k., make it certain 

 that the plants of the Glenrose, Tex., region which belong to the lower nonmarine
