which were described and figured by Dr. Owen in his final report on the 
Geology of Iowa, Wisconsin and Minnesota. The notes made by Dr. 
Evans on the geological features of that remarkable region were likewise 
of the highest interest, and from these Dr. Owen has compiled one of 
the most instructive and beautiful chapters to be found in his valuable 
report. In addition to his scientific duties, Dr. Evans had almost exclu- 
sive control of the business department of Dr. Owen’s survey, which of 
itself involved an immense deal of labor. The satisfactory manner in 
which he discharged these onerous duties, often in the midst of clis- 
heartening privations and even danger, commanded the highest esteem
