CLASSIFICATION BY THE BUREAU OF SOILS 85 



erally, having a light brown or yellowish color. The topography 

 is gently undulating to rolling. Corn and wheat are the principal 

 crops grown. Nearly four million acres have heen mapped. 



Cazenovia Series. These soils are brown in color with a brown 

 to reddish subsoil resting on limestone at a depth of about 3 feet. 

 Fragments of limestone and red sandstone are found throughout 

 the soil and occasionally large boulders are scattered over the sur- 

 face. These soils are derived from glacial till containing consid- 

 erable limestone material. The principal crops are grass, alfalfa, 

 corn, wheat, and potatoes. 



^ Coloma Series. The soils of this series are light brown to 

 grayish in color with yellow or reddish subsoils. The topography 

 is generally rolling to rough and hilly, representing terminal and 

 ground moraines. The series is formed from relatively coarse 

 glacial material modified to some extent by the action of the wind 

 and water. They once supported extensive pine forests and are 

 found in northern Michigan, Wisconsin, and Minnesota. Nearly 

 two and one-half million acres have been mapped. 



Cossaymna Series. These soils are brown or snuff colored, 

 with subsoils of the same color, but of a lighter shade. Both strata 

 contain considerable quantities of shale and calcareous sandstone 

 fragments with a small percentage of foreign boulders. They are 

 derived from glacial till and occupy rolling to hilly uplands. The 

 principal crops are corn, oats, hay, potatoes, apples and other 

 tree fruits. 



Dutchess Series. The Dutchess soils are brown to light brown 

 with bluish, light brown, yellowish or reddish brown subsoils. The 

 soils are friable, the subsoils being somewhat heavier in texture 

 than the soil. In some types rounded and angular gravel occur in 

 both soil and subsoil. Those are rarely of limestone. The to- 

 pography is rolling to undulating and rough. The soils are adapted 

 to oats, grass, potatoes, and tree fruits. 



Flushing Series. The soils are brown in color and overlie yel- 

 lowish or reddish subsoils, sometimes micaceous and in some in- 

 stances resting on crystalline rock. The material is of glacial origin. 



Gloucester Series. The soils of the Gloucester series are light 

 brownish or often grayish at the immediate surface and overlie yel- 

 low subsoils. The soils are derived from a rather local glaciation 

 of crystalline rocks of granites aiid gneiss. The drainage is fair 

 to good. The topography ranges from gently undulating to rolling 

 or hillv. Scattered rocks and boulders of large size occasionally
