can be made from materials at liand in tliis State, a Portland cement quite as good 

 in quality as the imported article; and that this can be done in Kansas at an expense 

 much less than in any other State in the Union, is equally well established. 



ANALYSIS OF KANSAS SOILS. 



By G. E. Patrick, Professor of Chemistrj^ and Physics, in University of Kansas. 



I have recently submitted to analysis samples of two soils from Wallace county, 

 Kansas. As the results show them to be quite rich in certain elements of plant- 

 food, and as no soils from that part of the State have heretofore been analyzed, it 

 may not be out of place to submit a report of my analyses to the Academy. 



Both samples were collected in September, 1875, by Mr. S. W. Williston, member 

 of Professor Mudge's geological party. Neither of the plats from which they were 

 taken has ever been cultivated. 



Both samples were thoroughly air-dried, at ordinary temperature of the labora- 

 tory, before analysis. 



SAMPLE NO. 1. 



Tills was an upland soil, taken from the high prairie of Smoky Hill Valley, near 

 Monument Rocks, Wallace county.

SAMPLE NO. 2. 



This sample was taken from the upper loam of the Smoky Hill Valley bottom 

 lands, thirty miles east of Fort Wallace, Wallace county.
