 the density of this undergrowth, that we seldom could see a mound until we were directly upon it; and we are not sure that all were detected. At the time of our visit a fire was raging through the woods about us, consuming the dry leaves and brush, and filling the air with smoke; and our clothes and persons soon became blackened by the charred bushes, nor were we entirely free from danger arising from falling trees. The peculiar noise made by the fire as it entered the marsh, caused by the bursting of the hollow stems of coarse grass and weeds, was very great.
Traces of a few other mounds were noticed at the eastern extremity of Pewaukee Lake, immediately north of the village. They were too much injured in the process of making roads, and by the dam, by which the lake has been raised four feet above its original level, to admit of their precise nature being ascertained.
No other ancient works could be found in the valley of the Pishtaka and its branches; nor could we hear of any more upon inquiry among those familiar with the localities in that part of the country.
