lar manner, upon the table -land upon which the above work is situated. In some 

 places it occurs in long, narrow ridges, conforming to the general course of the 

 terrace bank ; in others it forms amphitheatres of various sizes ; and in a few in- 

 stances it assumes a conical shape, resembling artificial tumuli. A short distance to 

 the right of the work under notice is a small natural amphitheatre, rising in the 

 midst of the marshy grounds, which has been supposed by some to be artificial. 

 Its relative position is indicated by the letter e. 



About one and a half miles southeast of the above work, was formerly another 

 of perhaps larger size. It occupied a high, oval-shaped hill, one side of which is 

 very steep, while the other subsides gently to the general level. The embankment 

 extended in a semicircular form around that part of the hill not protected by 

 nature ; and, previous to the cultivation of the ground, was upwards of six feet in 

 height from the bottom of the trench. A very slight depression, and the greater 

 luxuriance of the verdure, resulting from the filling of the trench with surface loam, 

 are all that now indicate the original lines. It is said that there was an avenue 

 leading oflT, for some distance, to the westward ; but it is no longer traceable. At 

 the base of this hill is a boulder, in which are several artificial depressions, doubt- 

 less intended for mortars, and a variety of grooves, in which the stone axes and 

 other implements of the aborigines were rubbed, in order to reduce them to the 

 required shape.

ANCIENT WORK ON " DRY HILL," FIVE MILES SOUTHEAST OF WATERTOWJV, JEF- 

 FERSON COUNTY, NEW YORK. 



Following the brow of the terrace northward from the work first described, for 

 about two miles, we come to another work of somewhat more regular figure, and 

 of larger dimensions. Most of it is under cultivation, and the outhnes are very 

 much defaced. The embankment, upon one side, runs into the forest land, where 

 it is well preserved, measuring, perhaps, three feet in height. The darker lines of 

 the engraving show what parts are still distinctly marked ; the dotted lines those 

 which have been ploughed down, and which are no longer distinguishable from the 

 general level, except by the deeper green and more luxuriant growth of the grass 

 on the line of the ancient trench. The position of the work, it will be seen, corre- 

 sponds very nearly with that of the one previously described. There is, however,
