British Inch as the U'nit of Measure of the Alonnd Builders, z^y 



is 4200 inches, and one-fourth of this is 1050 inches This relation 

 is significant, because the measure of 1050 feet is the second most 

 conspicuous one in the mound works. So also, 350 is ther everse 

 of 530. and 530 feet as will be seen is part of the side of a s(|uare 

 forming the chord of a great circle, in the Hopeton Works. 



No. 2. Plate 21, page 57, (we cjuote from Squier and Davis 

 work,) gwQ'ifoiir works, similar to No. 1, the sc^uare in each being 

 1080 feet to the side. 



(a) A work on Paint Creek, a tributary to the Scioto river, 

 14 miles from Chillicothe, 



(b) A work on "The Crossings of Paint Creek." The great 

 circle is about 1687 feet in diameter, and contains an elliptical 

 mound 140 feet long by 160 feet broad, and 30 feet high; also a 

 small circle 250 feet in diameter. The length of the mound is to be 

 noticed, tor it is 1680 inches, a multiple of 42, which number di- 

 vided by 4 is 105. 



(c) A work on the Scioto river, i mile south of Chillicothe. 

 The great circle of this work has a diameter of about 1625 feet. 



(d) A work at Frankfort, or Old Chillicothe, on the left bank 

 of the North Fork of Paint Creek. The great circle of this work is 

 about 1625 feet in diameter. 



In addition to the works mentioned, we have as especially 

 setting forth the measure of 1080 feet: — 



(i) The great square connected with the cone and ellipse, at 

 Marietta, on the Muskingum river. This scjuare measures 1080 

 feet to the side. Plate 26 page 73. 



(2) The great rectangle at Winchester, Indiana. This rec- 

 tangle measures upon one side 1080 feet, upon the other 1320 feet, 

 or just one-fourth of a mile. If we add the length of these sides, 

 we have 2400. The number 24 is constantly being used in the 

 works in connection or contrast with 42 its inverse. 4^ times 24 are 

 108, and 42 divided by 4 is 105. It we subtract 1080 from 1320 

 we have 240. Plate 33, page 93. 



(c) The great rectangle at Hopeton, on the Scioto river, 4 

 miles above Chillicothe, connected with a great circle. One side 

 of this rectangle is 10800 inches in length. The great circle is in 

 diameter 1050 feet. Here the numbers 1050 and 1080 are brought 

 immediately together. 



(4) Two great rectangular enclosed parallels, each 750 feet 

 long by 60 feet wide, or 9000 inches long, by 720 inches wide.
