CHAPTER II. 



EARTH-WORKS, ENCLOSURES, ETC. 



For the sake of convenience and easy reference, the enclosures of earth are arranged 

 according to counties, and so described. Works which were constructed of pahsades sim- 

 ply, without embankments or ditches, do not fall within this arrangement, but will be 

 described collectively in a separate chapter, under the head of " Palisaded Enclosures."
