OTSEGO COUNTY- 



It is stated, upon very good authority, that an ancient circular earth-work once 

 existed near Unadilla, in this county. Nothing is known concerning it, further 

 than that it was situated on low ground. 



CHENANGO COUNTY- 



There was formerly an ancient enclosure, of small size, within the limits of the 

 village of Oxford, in the township of that name, on the banks of the Chenango 

 River. It is described by Clinton as occupying a small eminence, three or four' 

 acres in extent, which rises abruptly from the flats bordering the river. At the 

 base of this eminence, upon the western side, flows the stream, and here the descent 

 is precipitous. A line of embankment and a trench extended in a semicircular 

 form from this bank, leaving narrow interruptions at the ends, for ingress and 

 egress. The area thus enclosed was about three-fourths of an acre. At the 

 period of the first settlement, it was covered with a dense forest ; yet, says Mr. 

 Clinton, " the outhne of the work could be distinctly traced among the trees, and 

 the elevation from the bottom of the trench to the top of the embankment was 

 about four feet. The stump of a decayed pine which stood upon the wall exhibited 

 one hundred and ninety-five cortical layers, and there were many more which could 

 not be counted, as the heart of the tree alone remained. Probably the tree was 

 three or four hundred years old, — certainly more than two hundred. It probably 

 stood many years after it had completed its growth, and it is reasonable to suppose 

 that some time elapsed from the period of the construction of the work to the 

 commencement of the growth of the tree.
