��eral other effigies, and thirty or forty mounds and embankments, on the same terrace with the birds, which have been removed in grad- ing streets and lots.
No. 3 is near Richmond Station, on a terrace about twenty-four feet above the river. It is seventy-six feet in an air line from tip to tip of the wings ; and the bod}', with head and tail, is fort3'-four feet in length. The body, to the first joint of the wings, is fifteen inches in height. Formerly a number of ordinary mounds existed in the immediate vicinity of this effigy.
No. 4 is situated near the village of Dakota,
��be enumerated from all the published survej's together.
The effigies survej'ed by mj'self, in addition to the twenty-five in Minnesota, are one in Iowa, and ninety-six in Wisconsin, — a total of a hundred and twentj'-two to the present time. On critically examining their delinea- tions, very important diflferences in class and style from those farther east, portrayed in Lapham's work, are discernible ; so that one is irresistibl}- drawn to the inference, that, before generalizations of value can be made, ten times the number of facts now recorded must be gathered together. Unfortunately', however,

Its length is a hundred and ten feet, and the centre of the head is two feet and a half in height. It undoubtedly represents a fish. This is the first case that has been dis- covered of a fish with fins.
In the limited territory hitherto examined by me in south-western Wisconsin, it would seem, from the numerous ruined effigies, that there formerly existed hundreds of such works. Judge Gale of Galesville estimated that there were full^' one thousand effigies in the southern part of Trempeleau county alone ; and, from my own observations, I should say a like esti- mate for Vernon and Crawford counties would be rather under than over the truth. Taking Judge Gale's estimate for Trempeleau county, and reducing it one-half, there would still re- main more effigies in the one county than can

In conclusion, something might be said on the question of the relation between any relics contained in this class of mounds and their shapes. The fact is, however, that little, if any thing, has been understandingly done with a view to ascertain their contents. The few effigies opened along the Mississippi have shown relics and fonns of interment similar to those of the common burial-mounds of their neighborhood. T. H. Lewis.
