of Cottonwood creek. Leaving the road here, we went down 
the Cottonwood valley some thirty miles, when we turned 
across the country nearly due northward to Council Grove. 
From the latter place we followed the Santa Fe road back 
southwestward about twenty-four miles to a watering-place 
known as ‘Lost Spring’; here we again left the road and struck 
across the country in a northwest direction to Smoky Hill river, 
at a point nearly opposite the mouth of Solomon’s Fork. We 
then traveled down the south side of Smoky Hill and Kansas 
rivers to Lawrence, where we crossed the Kansas and pro- 
ceeded in a northeast direction back to Leavenworth City.” 
Professor Meek also did considerable work on both sides 
the Missouri river from Leavenworth to Omaha, and pub- 
lished results of his investigations in the Final Report of the 
United States Geological Survey of Nebraska and Portions of 
Adjacent Territories, published in Washington in 1872. Par- 
ticular reference should be made to the article by Meek begin- 
ning on page 83 of this report. In all of their work in Kansas 
Meek and Hayden did but little in the way of suggesting 
detailed geological names to individual formations, and 
contented themselves with the use of numerals for such desig- 
nations. They performed an important part, however, in rec- 
ognizing the great divisions in Kansas, such as the Carbonifer- 
ous, Permian, Cretaceous, etc. 
Prof. G. C. Swallow, although located in Missouri, made a 
- great impression on early Kansas geological literature. In a 
degree he was associated with Major Hawn in the recognition 
of the Permian in Kansas. One writer, in discussing this sub- 
ject, wrote as follows :? 
“The early geologists of the state, Hawn, Swallow, Meek 
and Hayden, engaged in a spirited controversy, not only in 
regard to the correlation of the geological formations of this. 
part of the state, but also as to whom belonged the honor of an- 
nouncing the discovery of the Permian rocks in Kansas. Major 
Hawn stated that his first impression that the rocks in ques- 
tion might be of Permian age was obtained from a letter writ- 
ten by Mr. Meek September 3, 1857. (Am. Jour. Sci., 2d 
series, vol. XXVI, p. 188; ibid, vol. XLIV, p. 38; Trans. Acad. 
Sci. St. Louis, vol. 1, p. 511.) On January 19, 1858, at the re- 
quest of Meek and Hayden, a record was made at the Smith- 
sonian Institution in which is mentioned ‘forms indicating 
Permian both in Kansas and the region of the Black Hills.’
