departments of Geology, Biology, Botany, with their lecture 
rooms and offices, and the office and laboratory of the geologi- 
cal survey. The mineralogical and biological laboratories of 
the respective departments, fitted with tables and apparatus, are 
in the end of the building nearer the reader. There is to be, 
according to the plan, a school of mines with the necessary con- 
veniences in the same part of the building, the general assay 
room being in the basement, and the office and drafting rooms 
on the first floor in front. 
In the accomplishment of the progress of the University in 
these departments during the past twenty years, briefly rehearsed 
above, the chief agent has been, manifestly, that enlightened 
public spirit and appreciation of science which characterizes 
generally the communities of the western states. It is evident, 
however, that this alone would not effect the result so quickly 
unless it be directed by enlightened and judicious administrative 
application. The Board of Regents of the University during 
this double decade have not been a fluctuating and uncertain 
body. Some of the present members have served uninter- 
ruptedly through the whole period, and they have uniformly 
been friendly to the development of the scientific aspects of the 
institution. 
FOLIATION AND SEDIMENTATION. 
A Reply to Prof. Alexander Winchell. 
By Andrew C. Lawson Pn. D., of the Geol. Survey of Canada. 
In the fifteenth annual report of the state geologist of Min- 
nesota, Prof. Alexander Winchell discusses* some considerations 
bearing upon the origin and history of the Lauren tian gneisses 
which were advanced by me in a reportf on the Geology of the 
Lake of the Woods. 
The criticism came to my notice last spring and as the argu- 
ments put forward in it to show how he "would propose to 
overcome Mr. Lawson's difficulties," seemed very inadequate to 
enable me to overcome the only difficulty which I experienced, 
namely, the insuperable one of swallowing the currently ac- 
cepted metamorphic theory, in its application to the Laurentian
