 which is now a cultivated field, but was formerly covered with 

 oak timber. The field has a gentle slope towards the marsh from 

 a rocky ridge, composed partly of what appears to be limestone,

 surrounding portion of the ridge, and its soil bears evidence of 

 having been washed from the ridge, and, as has been stated, now 

 forms part of the upper surface of the marsh. It was under this 

 deposit, and at the depth of from two to twelve feet, imbedded 

 in the marsh, that these bones were found, lying in the utmost 

 confusion, and disorder."
