The several ponds, it will be seen, have outlets for the water 
at particular points, which probably were controlled as the mound 
builders desired. The large embankment, (e,f,@), is abruptly 
cut off at s, and continued again towards h, diminishing in mag- 
nitude as the land grows higher, till it almost disappears at 7. The 
swale continues up to very near the pond at J, but has no actual 
connection with it. It does not appear that the lake in the 
woods, within this leveé, has been produced by excavation. The 
smaller ones adjacent, however, are manifestly produced by 
throwing up the earth about them, as at e,f. The whole work, 
although exhibiting very little ingenuity, bears evidence of the 
vastness of the population, their industry, and not less certainly 
their ignorance and folly.

Culm near two feet high, glabrous, acutely triquetrous, sca- 
brous above, erect, leafy towards the base; leaves linear, narrow, 
scabrous on the edge, sheathing and long as the culm, with short
