admeasurements by the authors. It may l)e relied on as strictly 

 correct.'' A similar explanation is made on " page 73 " as to the plan 

 of the Marietta works. 



But apart from these statements of exactitude there is a ])roof 

 of it to be had from the measures themselves. The works consist 

 of groups, in some instances separated from each other by many 

 miles, yet on the compilation from the field notes it soon became 

 manifest from the surveys that there was identity of groups and 

 measures as stated. Thus besides the care taken in the admeas- 

 urement:: of individual groups, justification was found in the agree- 

 ment of measures of these with other and similar groups, upon 

 which equal care had been bestowed This statement is made by 

 the authors. 



As to the coincidences of measures : 



" It is not to be supposed that these numerous coincidences 

 are the result of accident." (Page 71.) " Although in the progress 

 of investigation singular coincidences were observed between these 

 works, yet there was at the time no susi)icion of the identity which 

 subsequent comparison has shown to exist." (page 56.) Again: 

 "There is one deduction to be drawn from the fad that the figures 

 entering into these works are of uniform dimensions, which is of 

 considerable importance in its bearing iq)on the state of knowledge 

 among the people who erected them. It is that the builder pos- 

 sessed a standard of measure and had some means of determining 

 angles. * * The coincidences observable between them could 

 not have been the result of accident, and it is very manifest that 

 they (the works) were erected for common purpose. What the 

 purposes were the reader must judge. Without entering into any 

 argument upon the subject, we may content ourselves with the 

 simple expression of opinion that they were in some manner con 

 nected with the superstitions of the builders." (Page 61.) As to a 

 /////y//r work in Seal Township, Pike County, Ohio, they say : "It 

 is impossible to resist the conviction that some significance attaches 

 to these singular forms." (Page 67). As to the Portsmouth wcjrks 

 they say: " Whatever may have been the divinity of their belief, 

 order, symmetry and design were among his attributes; if, as 

 appears most likely, the works that most strongly exhibit these fea. 

 tures were dedicated to religious purjjoses, and were symbolical 

 in their design." (Page 82.) As to the works in Montgomery 

 County, Ohio: " It tends to confirm the impression produced by 

 the other works that some significance attaches to the combination
