The fossil plants come from ])e(l No. 3 and, O. B. Hopkins, L. C. Cliapman, and E. H. 

 as previously stated, were not abundant at Finch from a large number oi localities within 

 the time of my visit, but Veatch made some a few miles of the town of Naborton. Accord- 

 remarkably fine collections from these con- uig to these geologists the plants were found 

 cretions in 1898, which are preserved at the in the upper part of the section of the Wilcox 

 New York Botanical Garden. These were of western Louisiana and their determination 

 reported on by HoUick^ in 1900. I have of the geologic horizon is striking^ confirmed 

 restudied these collections, and the following by a study of the flora. I am indebted to
