SURFACE FEATURES OF THE VARIOUS TOWNS. 



Farmington. This was a prairie town originally. It is quite broken in the southwestern 

 portion, and an isolated mound, rising 150 feet above the surrounding surface, stands in the 

 northeastern. Otherwise the surface is undulating, with fine loam soil, becoming sandy near the 

 bluffs. 



Oronoco. The bluffs of the Zumbro and of its western tributary crossing this township 

 give It great diversity of surface characters. The bluffs are frequently rocky and rise over a hun- 

 dred feet perpendicular. In other places they are covered with gravelly clay and gravel, so that 

 no rock is visible, or very little, but the valley still is deep and difficult. Outside the valleys, 

 which are generally timbered, the undulating prairies spread out indefinitely.
