20 GEOMETRICAL EARTHWORKS OF OHIO. 
height from 5 io 14 feet. The ditch varies in width from 28 to 41 feet 
and in depth from 8 to 15 feet. 
The following are the notes of a survey by Mr. Middleton in 1888, 
commencing at station 1, in the gate-way:

From the plat made according to these figures we ascertain that the 
longest diameter, namely, that running northeast and southwest, is 
1,189 feet; and the shortest—southeast and northwest—is 1,163 feet; a 
difference of 26 feet. Although nota true circle, the difference between 
the longest and shortest diameters falls much short of 100 feet, as 
stated by Messrs. Squier and Davis. 
CIRCLE OF THE HIGH BANK WORKS. (ANC. MONUMENTS, PL. XVI.) 
These works occupy a broad, unbroken level of the drift terrace, which 
has been cultivated almost annually since 1845. The walls of the cir- 
cie and octagon are still quite prominent, and are respectively 2 and 5 
feet high. (See Pl: VI.) 
This circle is very similar in size and other respects to the ‘ Observa- 
tory Circle” at Newark, and, like that, is connected with an octagon, 
though the relative sizes of the two inclosures differ in this respect, the 
octagon of the Newark works is larger than the circle, while that of the 
High Bank works is smaller than the circle. We see in this group the 
tendency to combine circles, octagon, and parallels as at Newark, 
making it probable that the works at both points are due to one people. 
According to Messrs. Squier and Davis this circle is a ‘‘ perfect” one, 
the diameter being 1,050 feet, which, as will be seen by what follows, 
agrees very closely with the result of the resurvey.
