of this work "was done wholly without expense to the State, and 
that the remainder was done at such a nominal expense that it is al- 
most without a parallel in the history of public investigations of 
this kind." The same remark is equally true of all of this Kansas work. 
It is the plain duty of the State to encourage these eflforts so well 
begun. From a financial standpoint, let alone all others, it would 
be a good investment to Kansas to extend liberal aid. For every 
dollar thus expended the return is a thousand to the citizens at large. 
Such commendable activity as is shown by^the Kansas workers should 
not be allowed to go without public recognition in the way of ample 
funds to still further enable this most laudable enterprise to go on 
as it should. 
The first part of the volume, by professor Hawortn, gives a com- 
plete summary of all the work previously done by the instructors 
and students of the university during the prosecution of the univer- 
sity geological survey, so far as this has pertained to the coal meas- 
ures. The various terranes before recognized are described anew, 
some new divisional lines are made and some new names of forma- 
tions are proposed. The classification now presented is essentially 
as follows:

The second part, by Mr. W. E. Crane, which makes up the greater 
portion of the volume, is devoted chiefly to the commercial aspects 
of the Kansas coal, the methods of mining and the character of the 
mine machinery. A considerable portion of this embraces also many 
details regarding the stratigraphy and the local peculiarities of sec-
