5S EXPEDITION TO THE 



is about one hundred and fifty feet; it is provided with a 

 gateway fronting that of the first fort. Between the se- 

 cond and third forts, (B. and C.) and near the bank of the 

 river, there are remains of a water-way, (W.) formerly 

 connected as we suppose with the third fort; these remains 

 consist of a dltcli dug down to the edge of the river ; the 

 earth from the same having been thrown up principally 

 on the south side or that which fronts down the river, the 

 breadth between the two parapets is much wider, near the 

 water, than at a distance from it ; so that it may have been 

 used either for the purpose of offering a safe passage down 

 to the river, or as a sort of harbour, in which canoes might 

 be drawn up; or perhaps, as is most probable, it was in- 

 tended to serve both purposes. This water-way resembles 

 in some respects, that found near Marietta, but its dimen- 

 sions ai-e smaller. The remains of this work are at present 

 very inconsiderable, and are fast wasting away, as the road 

 which runs along the bank of the river intersects it, and 

 in the making of it, the parapet has been levelled and the 

 ditch filled up ; this is much to be regretted, as this work, 

 if it could be seen in its perfect state, would perhaps dis- 

 cover the motive which led to the erection of these fortifi- 

 cations, the attacks against which they were intended to 

 provide, and the means with which the resistance was to 

 be effected. But the largest of the works on the western 

 bank, still remains to be noticed. This is an elliptical 

 construction, (D.) of great eccentricity; its transverse and 

 conjugate diameters measuring eighty-three and two hun- 

 dred and ninety -five feet; it is situated six hundred feet in a 

 direction north forty degrees east from the first fort, its een- 

 jugate axis extends nearly east and west; we observed no 

 gateways ; this work is almost^effaced, its parapet does not 

 rise quite one foot above the ground.
