A Discription of the Fortification

(1) Commenceing on the river opsid the Good Mans Island, first Course from the river is

S. 76d W. 96 yards thence

S. 84 W. 53 yards (at this angle a kind of angle or horn work)

N. 69 W. 300 yards to a high part, passing the gateway Covered by two half Circler works one back of the other lower than the main work the gate forms a right angle projecting inward

N.32 W. 56 yards

N 20 W. 73 yards This part of the work appears to have either double, or a covered way. from this Some irregular works appear to have been on mounds between this and the river with a Deep round whole in the center of a gorge formed by another angle ------ (578)

This part of the work is from 10 to 15 feet 8 Inches- the mounds of various hights- the base of the work is from 75 to 105 feet, steep inward and forming a kind of Glassee out wards

in this Course at 533 yards a Deep Pond of 73 yards Diameter perfectly round is in the Course of the bank which is about 8 feet high, from this Pond the bank it lowers gradually- a bank about the Same hight runs near the river, and must have joined the main work at a part which is now washed into the river, this is also perfectly Streight and widens from the main work, as the river above has washed in its banks for A great distance I cannot form an Idear How those two long works joined- where they Strike the river above, they are about 1100 yds apart, I am informed by our freench interpeters that a great number of those antint works are in Different parts of this Countrey, on the Platt River, Kansus, Jacque, Osarge Mine river &c.
