Miami silt loam. — Light-brown or yellow, sometimes reddish 



silt loan, from 8 to 12 inches deep, underlain by a plastic silt loam 



or silt clay of a reddish or yellowish color, grading at 14 to 16 



inches into a tenacious silt loam having the proprieties of a clay. 



Occupies level prairies and slightly rolling areas. Origin is due 



to the deposition of loess over glacial till. The soil 'is very fertile, 



producing good yields of wheat, corn, clover, and timothy hay. 



The average yield of wheat is 20 to 30 bushels, and of corn from 



25 to 50 bushels per acre.

cit is probable that this should have l)ec'n niai)i)e(l in i)art as Marshall silt 

 loam. At tlie time the dill'erences between the soils locally known as the "clay 

 land" and the "dark loam " did not appear sutlicient to justify a separation into 

 two types, but with v.'ider experience in soils of this chivss, it appears that the 

 latter soil should have been mapped as Marsliall silt loam. 



''Mapped as Tazewell silt loam. It is probable that this soil should have 

 been mapped in part as Miami silt loam and in part as Marshall silt loam.
