In map No. Ill, section 4, Bloomington Township, is shown another 

 illnstration of special interest. This occurs at the rather abrupt turn of 

 Bean Blossom Valley, on the northeast side, where the upland forms a 

 point projecting into the valley. The point shows the same sort of to- 

 pography (see Plate No. Y) as noted in other cases— the rounded tops, in- 

 creasingly steep slopes, descending Td the valley tloor, and the neck 

 connecting it with the upland on the north. This case attains additional 

 interest, as just to the west and opposite the gap or sag betAveeu the 

 knob and the upland, is a bench varying in elevation above the valley 

 floor from twenty to forty feet, and flanking the slopes of the projecting 

 headland and spur. The geographical signiflcance of the benches will 

 be observed in another part of the paper. 



Sketch Map No. III. Section 4, Bloomington Townshiii. 



In rlie center of the valley floor and just opposite (or to the south of) 

 the last named spur, and also up str(>am fur some two and one-half miles, 

 still more evidence of valley tilling is app.-ireiiT. To the southeast of the 

 point occurs a rather subdued ridge, somewhat irregular in relief, extend- 

 ing up stream for three-(iuarters of a mile, or thereabouts. A portion of 

 this is shown in sketch mai> NO. 111. lienn Blossom flows close to its 

 northern edge. On the south side of tlie elevation flows Muddy Fork 

 Creek from tlie soutlieast. and readies Bean Blossom some distance be- 

 yond its west end. So full lias Bean Blossom, and its tributaries, as well, 

 been flUed with waste that the aggraded floor of both valleys have for 

 some distance up the respective streams from their junction merged into 

 one broad flat floor.
