388 ARCHAEOLOGY. 



tlie vicinity of the city. An acconnt of these mounds was published 

 in 1828 in a note to the first volume of Long's Expedition, page 59, 

 but without the map, which was omitted to give place to what was 

 considered more important matter, and has remained unpublished 

 until now. The survey, although not made with great precision, was 

 sufliciently accurate to give a definite idea of the form and relative 

 position of the mounds. 



The following notes were made at the time and published by Mr. 

 Say. The opinion of my much-respected friend concerning the ol3Jects 

 of these earthworks, given in the extract, have since been corrobo- 

 rated b}' other observers : 



" Tumuli and other remains of the labors of nations of Indians that inhabited 

 this rcfi:ion many ages since are remarkably numerous about St. Louis. Those 

 tumuli immediately northward of the town and within a short distance of it are 

 twenty-seven in number, of various forms and magnitudes, arranged nearly in a 

 line from nortli to south. The common form is an oblong square, and they all 

 stand on the second hank of the river. The statement given beloAv of the 

 forms, maguitudes, and relative position, is the I'esult of actual admeasurement 

 taken with care, and with as much accuracy as their present indefinite bounda- 

 ries, together with the dense growth of underwood covering their surface, and 

 tending to beguile and obstruct the vision of the observer, will admit. |A 

 pocket compass and tape measure were the only instruments used.j 



" It seems probable these piles of earth wei'e raised as cemeteries, or they 

 may have supported altars for religious ceremonies. We cannot conceive 

 any useful purpose to which they can have been applicable in war, unless as 

 elevated stations from which to observe the motions of an approaching enemy; 

 but for this purpose a single mound would have been sufficient, and the place 

 chosen would probably have been different. 



"Nothing like a ditch or an embankment is to he seen about any part of these 

 works. 



" What we have called hase in the following statement, is in reality the length 

 of a line passing over the top of the mound from the termination of the base 

 each side. 



" The numbers refer to the mnp. The heights are estimated, With the excep- 

 tion of two." 



No. 1 is the remains of what was reported to be the bastion of an 

 old Spanish stockade, indications of a ditch being still visible. 



No. 2. A square with a hollow way, gradually sloping to the top; or 

 in other words, a hollow square, open behind.
