"No. 1 has eleven mounds, situated on the crest of a divide. The general direction of locations is from north to south, or south to north. The correct location, I believe, is from south to north; that is, they point to the north. These mounds are now raised about three feet above the level, and are uniformly thirty feet in diameter. Counting from the south, the sixth and seventh are generally within a few feet--come very near touching each other; the others are as near as, may be, two diameters apart. These remarks will apply to No. 2, No. 3, No. 5 and No. 6. No. 2 has eleven in a line (as No. 1,) and then three mounds to the east appear to be parallel, and may have had the remaining eight removed by cultivation. No. 4 is on the bottom--second bench land; are a little larger in size; the others, to make out the eleven, may have been destroyed by cultivation. No. 7 has eight in position, and then a valley intervenes, and the three additional, making the eleven, are on the ridge next to the north. No. 8 has twelve. They are on the crest of a divide which passes around the head of a deep ravine, and follow the divide at the angle. Most of these mounds (No. 8) have been lately opened, but we think no relics were found. We have been careful to find the place that the earth composing the mounds was taken from. Generally, the banks of a near ravine indicate, by their shape, the place. Under the strongest sunlight, in a mound cut through the center, we could detect no indication or difference in the clay to show that it had been removed or disturbed, or that there had been any remains in it to discolor the clay in their decomposition. "Let it be observed that the mounds are substantially north and south in line of location. They are eleven in number, uniform in size, and, I believe, cover every ridge in the vicinity of the rapids of the Cedar having the direction sufficient in length on which the mounds could be placed. They are built in the locality the least likely to be disturbed, and in the shape and of the material the most enduring. There certainly was intelligence displayed in their location and in the selection of the material of which they are constructed, as well as in the design of their form and positions. There may have been more mounds than these, but these are all that are left--all that are left of that race which might have sent from their number emigrants to people the new land, to the far west, the last continent, fresh and vigorous from the ocean, the newest born, the best then adapted for man's material and mental development."--_History of Linn County_, 1878, p. 319.
