large tuunilus A, is a gateway (G), tlie original width of which, judgiug 

 from i>resent appearances, was 20 feet. The drainage of a portion of 

 the field is at present through this gateway. Along tlie line of the 

 embankment, where not effaced by the plow, are buttress like enlarge- 

 ments (S), projecting oiitwards from 20 to 30 feet. The distance be- 

 tween these enlargements varies, increasing fi'om east to west. Two 

 measured on the east were 07 feet apart, two on the north 107, and two 

 on the west 120 feet. Standing on the outer edge of one of these en- 

 largements a person commands a clear view along the line for some 

 distance. The eastern portion of the embankment rises C to S feet 

 above the level of the adjoining field and the top is nearly level with 

 the general surface of the field containing mounds A and B. 



Careful search was made for an embankment extending to the bluft" 

 on the west, but no indications of such could be discovered. There is 

 a ridge (shown by hachured lines on PI. xli) somewhat resembling 

 the earthwork already mentioned, which was found to extend east and 

 west for a short distance north of the regular embankment. It is wider 

 than the other and was traced to the edge of the woods, where all signs 

 of it were lost, nor could it be found beyond mound E. It is probably a 

 natural swell of the surface rather than an artificial structuie. No 

 ditches were found near either of the earth walls, if the latter may be 

 so called. 



There is an excavation of considerable extent, in which large forest 

 trees are growing, a short distance north of the inclosure. It is from 

 this excavation that the earth composing the large mound was in all 

 probability taken, as on the side towards this the slope is very gradual. 



Mounds A and B are situated on the farm of Charles Grimm, C, D, 

 and E on Silas Angel's farm, and mound F on Edward Collius's farm. 



The distances between the mounds, measuring from center to center, 

 are as follows:

In a few instances both in the eastern and western parts of the dis- 

 trict mounds have been explored containingstonegravesof the regular 

 box-shaped tyi)e. Also some instances occur of earth-mounds covered 

 over with a layer of stones, as mounds in southeastern Indiana and in 

 the Kanawha valley in West Virginia are found occasionally to be. 



A number of ordinary small burial mounds found on the bluffs and 

 higher grounds of Pike and Brown counties, Illinois, opened by the 

 Bureau agent, were con.structed in the usual method in this portion of 

 the district — that is, with a layer of hard mortar-like substance, or clay 

 and ashes mixed, covering the skeletons or bottom layer. The positions
