Fig. 6. — " This work is situated upon the 

 Cuyahoga river, eight miles above Cleveland, 

 Ohio. It corresponds, in all essential parti- 

 culars, with the one on the same stream, five 

 miles below, which has already been described. 

 The ground has been so long under cultivation 

 that the parallels are with difficulty traced ; 

 they are not more than a foot or eighteen 

 inches high. The ditch is of corresponding 

 depth. Between the lines there is a depres- 

 sion, — undoubtedly artificial in its origin, but 

 now much deepened by rains. The soil is 

 a clay-loam, and the area very difficult of 

 The blufT is here from one hundred and fifty to two hun- 



Fic. 7. — " This work is situated on the 

 Cuyahoga river, two miles below that last 

 described, with which it coincides in respect 

 to position. It has, however, but a single 

 wall and ditch ; the latter is from two to four 

 feet deep, the former of proportionate height. 

 There is a gateway or unexcavated passage 

 across the ditch, but no corresponding opening 

 in the embankment. There is, however, a 

 narrow, unprotected space between the left end 

 of the defences and the blufi". The elevation 

 of the ground is here about two hundred feet 

 above the river, the soil sandy, and lately put under cultivation. The bluff is steej) 

 and difficult of ascent. Water is found in the adjacent ravines, which are narrow 

 and deep." 



Fig. 8. — " This work is situated on the right bank of 

 the Maumee river, two miles above Toledo, in Wood 

 county, Ohio. The water of the river is here deep and 

 still, and of the lake level; the bluff is about thirty-five 

 feet high. Since the work was built, the cm-rent has 

 % undermined a portion, and parts of the embankment arc 

 to be seen on the slips at a a. The country for miles 

 in all directions is flat and wet, though heavily timbered, 

 as is the space in and around this enclosure. The walls, 

 F,„ ^ measuring fnmi the bottoms of the ditches, are from three 



to four feet high. They are not of uniform dimensions throughout their extent ; and 

 as there is no ditch on the south-west side, Avhile there is a double wall and ditch 

 elsewhere, it is presumable that the work was abandoned before it was finished."
