Identification of the British Inch as the Unit of Measure. 1 5 5 



While this statement was (as it is) of undoubted value as re- 

 gards the relics, yet the exceedingly great value of the " Gridley 

 Measure," as a discovered unit of measure belonging to the 

 Mound Builders and the construction of the " Mound Works " of 

 the Ohio Valley, made the writer collect all the facts possible with 

 regard to it, and he wrote Mr. Gridley, receiving the following re- 

 plies : 



"Springfield, Clark Co., O., Jan. 29. 1883. 



"Dear Sir : —Yours of the i8th is received. In answer to 

 your inquiries I would say that at the time of the removal of the 

 mound I was residing on Longworth Street, near Mound Street, 

 and often dug in it to find what I could. The relics were about 4 

 feet above the base of the same, and over a bed of ashes and char- 

 coal, in which were found several skeletons partly in the ashes. I 

 found the stone of this shape , and one with a hole in 



it, 2 stone chisels, and rough stone used to sharpen chisels on, 

 and a copper ring which was on an arm bone of a skeleton. It 

 broke in two after I found it and before I left it with the Antiquar- 

 ian Society. If you will refer to Mr. Carley's antiquarian book 

 you can find the day and date when deposited and the several 

 items found. I believe they were found in the spring of '46. If 

 you will call on the man who owns the lot he may be able to in- 

 form you of the year. As to th^ Ciest stone, I believe it was found 

 after mine. I think I saw it. The earth was deposited on Colum- 

 bia Street or Second Street — -the mound earth. If I could see you 

 I could give you a description of what I fo.und ; but did not retain. 

 I sold to Dr. Shotwell two skulls of singular form. A Mr. Clark 

 was with Mr. Carley when I left the relics with the Antiquarian 

 Society."

The second reply is as follows : 



"Springfield, Clark Co., O., Feb. 8, 1883. 



"Dear Sir : — In answer to your request I would say that it 

 was over the center of the mound that I found these relics, and 

 over the bed of charcoal of this form lying north and south 4x10 

 feet." 



(Signed) " C. P. Gridley." 



Thus the location of the finding this measuring stone was at a 

 depth of about 26 feet below the top of the ancient mound, and at 

 or near its center, and the location of the find saves the relic from
