251 Haworth (Erasmus). Relative value of limestone, sandstone, and 
shale for stratigraphic work in Kansas. 
Kans. Univ. Quart., vol. ii, pp. 102-104. 
States that in Kansas the limestones are more important for strati- 
graphic purposes than either sandstone or .shale, on account of their 
regularity and persistency in lateral extent. 
252 A geologic section along the Atchison, Topeka and Santa Fe 
Railroad, from Cherry vale to Lawrence and from Ottawa to 
Holliday [Kansas]. 
Kans. Univ. Quart., vol. ii, pp. 118-126. 
Describes the strata along the line of this section and correlates 
certain beds with those of other sections previously described. 
253 Resume of stratigraphy of eastern Kansas. 
Kans. Univ. Quart., vol. ii, pp. 126-129. 
Gives a general sketch of the succession of the formations in eastern 
Kansas as shown by the several sections previously described. 
254 The topography of eastern Kansas. 
Kans. Univ. Quart., vol. ii, pp. 129-136. 
Describes the general topographic features of eastern Kansas. 
255 The surface gravels of eastern Kansas. 
Kans. Univ. Quart., vol. ii, pp. 136-142. 
Describes the distribution of the gravels, and considers that they are 
residual products derived from the weathering of the underlying 
formations. 
256 and Kirk (M. Z.). A geologic section along the Neosho 
River from the Mississippian formation of the Indian Ter- 
ritory to White City, Kans., and along the Cottonwood 
River from Wyckoff to Peabody. 
Kans. Univ. Quart., vol. ii, pp. 104-115. 
Describes the limestones, sandstones, and shales outcropping along 
the Neosho and Cottonwood rivers. 
257 and Piatt ( W. H. H.). A geologic section along the Verdigris 
River from the State line to Madison [Kans.] 
Kans. Univ. Quart., vol. ii, pp. 115-118. 
Describes the stratigraphy along the Verdigris River. 
258 Hayes (C. Willard). Geology of a portion of the Coosa Valley, in 
Georgia and Alabama. 
Geol. Soc. Am., Bull., vol. v, pp. 465-480, pi. 18. 
Abstract: Am. Geol., vol. xiii, p. 142 (8 1.). 
Describes the physical features of the region and the succession of 
the Cambrian, Silurian, and Devonian rocks. Discusses the structure 
and gives a sketch of its Paleozoic and post-Paleozoic history. 
259 On the Devonian (Oriskany) in the southern Appalachians. 
Am. Jour. Sci., 3d ser., vol. xlvii, pp. 237-238 (communicated). 
Mentions fossils of Devonian facies found in a ferruginous sandstone 
in Alabama which rests on Trenton or Hudson River strata. Consid- 
ers the unconformity between the beds to be due to overlap of deposi- 
tion and not to faulting.
