its measures are : Extreme length exactly 5 inches. Greatest 

 width 2.99 inches, least width 2.50 inches. Chord of shallow arc 

 on each side 4.50 inches. 



Since writing the foregoing my attention has been called by 

 Dr. Hunt, ]:)resident of the Society of Natural History, to an 

 article in the May number, 1843, ^^ ^^^ " American Pioneer," 

 published in Cincinnati. This article describes and figures the 

 Gest tablet, and the Gridley relics, those referred to in his letter 

 above, which include the ^^ measuring stone.,'" the subject of our 

 main article. It speaks of '' Figure i " (the Gest tablet) as a 

 carved stone, found at the l)Ottom, and near the center of an 

 ancient mound, " now being removed from Mound Street near 

 Fifth, this city." The mound is described as about 25 feet high. 

 From the place where this was found, "about ten feet distant in 

 the mound, and nearly on the same level, were found parts of 

 another skeleton, with a beautiful stone ornament four inches long, 

 two inches wide and nearly an incli thick (figured), also, a stone 

 instrument nine inches long and three wide (figured) ; this is about 

 a fourth of an inch thick. The long straight side has a diamond 

 shaped edge, as if it had been used for dressing leather. These 

 (with others described) were discovered by and are in possession 

 of Mr. Ciridley of Longworth Street." The article says the Gest 

 tablet was taken from the mound in 1841, and this, with Mr. 

 Gridley's statement, fixes the date of the find of the " measuring 

 stone." 



APPENDIX B. 



The following ([notations are made from the The Smith- 

 sonian Report of The Ancient Monuments of the Mississip])i Val- 

 ley, to establish as far as possible the facts: (ij Of care and ac- 

 curacy in the measures of the mounds; (2) Of identities and 

 correlations of groups and measures, such as to prove in the minds 

 of the surveyors, the possession by the Mound Builders, of a stand- 

 ard of measure, and some means of taking angles correctly ; also 

 a scientific and religious object in the construction of the works, 

 and (3) Of a further proof of the correctness of the measures as 

 surveyed. 



As to taking and reporting the exact measures of the various 

 works :
