The physical properties of glacial soils are also dis- 

 tinctive. Excepting subsequent modifications due to 

 water, such deposits show little or no stratification or 

 sorting. They are heterogeneous in material and arrange- 

 ment. Much of such material is termed boulder clay, 

 from the mixture of coarse and fine particles. It is 

 also to be noted that such soils contain, relatively, a 

 larger proportion of silt particles, and a smaller amount
