the one hand it grades into the silt to loam type, while on the other it 
may be sandy, grading into the sandy loam. 
The difference in the character of the till as left by the glacier and 
the removal of the silt by the weathering and eroding agents are prob- 
ably responsible for the present structure of the Miami loam. The 
topography is similar to that of the Miami silt loam. 
Drainage.—The drainage of the Miami loam is usually good on 
account of the open, porous structure of the soil and the large amount 
of sand and gravel in the subsoil. In some cases, however, the subsoil 
is hard and compact, producing a poor natural drainage. In such cases 
artificial drainage would be beneficial and greatly increase the pro- 
ducing capacity of the soil. 
Crops Grown.—The crops grown on this type are similar to those of 
the Miami silt loam and they yield as good crops. Owing to the pres- 
ence of sand it can be more readily kept in a state of good tilth, but it 
quickly responds to good farming methods. The same farming methods 
will apply equally well in the Miami loam as in the silt loam types. 
Location.—The Miami loam is about as extensive as the silt loam 
and is largely south of the Wabash and Eel rivers. It is valued about 
the same as the silt loam types. 
MIAMI SANDY LOAM. 
Characteristics —The upper six inches consist of a grayish to dark 
brown fine sandy loam or fine loamy sand. The subsoil is a yellowish 
brown heavy loam grading at about eighteen inches into a sticky fine 
sandy loam or clay loam. In some places it changes to a yellowish sand 
mixed with some clay. 
Location.—It occurs in Cass County north of the Wabash River, 
becoming less sandy towards the river. A great deal of gravel occurs 
around Adamsboro and Georgetown. The sandy phase is associated 
with the sand ridges where the sand has been blown over the nearby 
land. The ridges are usually more sandy or gravelly, while the valleys 
contain a greater percent of clay. The topography ranges from level 
to undulating or rolling. Part has a morainic surface with more or 
less boulders. 
Drainage.—The drainage of the Miami sandy loam is more abundant 
and is apt to be somewhat droughty in more sandy areas. The depres- 
sions usually develop swamps which have little or no drainage. A num- 
ber of open ditches have been made, heading in the Muck and Clyde 
areas. Numerous wet quicksand areas occur on the hillside, where the 
water-bearing sands and gravel are exposed. These places are difficult 
to drain because of the continuous water supply.
