the sale of its lands, and thus enabled the company to com- 
plete its road at an early day. 
Soon after, Maj. Hawn assisted in the linear surveys in 
Kansas. While thus engaged he took careful notes on Kan- 
sas geology, being really the pioneer in that field, and 
brought together a very interesting collection of organic re- 
mains. These were brought to Columbia and carefully 
studied with Prof. Swallow, and on February 22, 1858, Prof. 
Swallow, in a conuiiunication to the St. Louis Academy of 
Science, announced the discovery of the Permian in Kansas, 
and at the same meeting Prof. Swallow offered a paper for 
])ul)lication entitled "The Rocks of Kansas," by G. C. Swal- 
low and F. Hawn. This was published in Volume L of the 
Transactions of the Academy, pages 173 to 198. In the same 
volume of Transactions, pages 171 to 172, Maj. Hawn con- 
tributes a paper o\\ the Trias of Kansas. This was the first 
announcement of such beds being found in Kansas. 
The series of fossils collected by Maj. Hawn in Kansas 
awakened great interest in western geology, and soon after 
Meek and Shumard also published papers on the Permian. 
F>etween the years 1865 and 1870 Prof. Swallow was state 
geologist of Kansas, with Hawn assisting in the work. Swal- 
low says (letter of Transmission, Jan. 8, 1866): "Maj. Hawn 
has given the survey the full benefit of his intimate and ex- 
tensive knowledge of the state and its resources. His reports 
are full of scientific and practical information." Swallow's 
geological report of Kansas includes Hawn's report of 25 
pages, with brief notices of the geology of the counties of 
Linn, Chase, Doniphon, Brown, Greenwood, Lyon, Butler, 
( ^sage and Morris. 
In 1853 Lieut. E. H. Rufifner, corps of engineers U. S. A., 
under the direction of the war department, made a reconnois- 
ance of the Ute country in southwest Colorado. Maj. Hawn 
accompanied the expedition as geologist and meteorologist, 
and Lieut. Ruffner, in his report to the war department, says 
of Hawn. "That Professor Hawn has been as faithful to his 
trust as could be desired is undoubted, and that little has 
escaped his eye is a natural consequence of his vmtiring in- 
dustry. I speak decidedly in giving my testimony to the 
efificiency of the geologist's assistant, L. Hawn. I beg to
