Graves had this to say in his 1808 book The History of Cleveland.
“Within this township, and nearly at an equal distance between the villages of Seamer and Newby, there is a remarkable tumulus, significantly called HOW-HILL, which is not known to have ever been opened. In the fields adjoining towards the south, on the side of a hill, are evident marks of entrenchment; and in the valley or plain beneath, it is reported that armour, swords and human bones have been frequently turned up by the plough.”
