made public, or that have as yet been discovered in the 

 western country. There the parapets and mounds were 

 Ibund connected in one series of works; whenever there 

 was an angle in the principal lines, a mound of the largest 

 size was erected at the angle ; the parapets were terminat- 

 ed by mounds at each extremity, and also at the gateways ; 

 no ditch was observed on either side of the parapet. In 

 many places the lines were composed of parapets and 

 mounds in conjunction, the mounds being arranged along 

 ihe parapets at their usual distance from each other, and 

 operating as flank defences to the lines." 



" The remains were observed in the interior of the coun- 

 try in a direction towards Kickapoo creek; they were 

 situated for the most part on the ridges, but a few also in 

 the valleys. Those on the ridges had the appearance of 

 having been intended to resist an attack on both sides, be- 

 ing for the most part a single parapet of considerable ex- 

 tent, crossed at right angles by traverses at the distance of 

 twenty or thirty yards from each other ; and having no 

 ditch upon either side. Those in the valleys appeared to 

 have been constructed to command the passage of the par- 

 ticular valleys in which they were situated. We saw no 

 works which exhibited signs of having been complete en- 

 closures, but the whole were in detached parts, &c." 



The following account of the nature of the country, back 

 of the prairie, extending towards Kickapoo creek, (a tribu- 

 tary of the Wisconsan, which empties itself on the north 

 bank about twenty miles above its mouth,) is extracted from 

 the same MS. 



" The country is divided into numerous hills or rather 

 ridges, of various shapes and dimensions, but generally 

 of an equal altitude, by valleys and ravines, some of 

 which have fine streams of spring water running through
