the greater j)ar1 of ihc l(Mi<i;tli of this canyon and its several l)ranches, as 

 well as faitliei' up on its sides, there are vast (|uantities of silicified wood, 

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

 Itluh's giving fine exposui'cs of Trinity sands witli clay seams. In one of 

 the.se there is a dark layer containing olxscure vegetable remains, among

After fiuther examination of the beds in thv ^•allev of the Paluxy, 1 

 crossed the divide to the Rosque, which also traverses Trinity strata, the 

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

 ensville to Hico, and I retvu'ned from the latter place to Granburv by way 

 of Glem-ose, having seen all the {principal phases of the Trinity formation, 

 and collected such specimens of vegetable natui-e as they yield. 



]\Ir. 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 arri\etl on January 22, 1S92. 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 pul)lished in the Proceedings of the United 

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

 distinct forms, 7 of whicli 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. Xo 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 ( Jlen Rose l)etls 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 spccinicn.s that you sent ine from near Murfreesboro, Ark., make it certain
