 the land of William Evans, section 36, of the same township. It rises 

 over three feet, and measures twenty-eight feet in circumference at the 

 surface of the ground. On section 14, Monterey township, the land of 

 Sebastian Bendley is very stony with bowlders over an area of about five 

 acres, with few fragments of limestone. The surface rises about three
