Indian population was never dense in North America. The best judges now agree that the entire native population consisted of not over two hundred thousand at the time when the Pilgrim Fathers came to Plymouth. Of these, Wisconsin probably had but nine thousand, which, curiously enough, is about its present Indian population. But, before the first whites came, many of the American tribes were not such roamers as they afterward became; they were inclined to gather into villages, and to raise large crops of Indian corn, melons, and pumpkins, the surplus of which they dried and stored for winter. We shall read, in another chapter, how the white fur trader came to induce the Indian agriculturist to turn hunter, and thereby to become the wandering savage whom we know to-day. Concerning the argument that the modern Indian is too lazy to build mounds, it is sufficient to say that he was, when a planter, of necessity a better worker than when he had become a hunter; also, that many of the statements we read about Indian laziness are the result of popular misunderstanding of the state of Indian society. It is now well known that the Indian was quite capable of building excellent fortifications; that the most complicated forms of mounds were not beyond his capacity; and that, in general, he was in a more advanced stage of mental development than was generally believed by old writers. Modern experiments, also, prove that the actual work of building a mound, with the aid of baskets to carry the earth, which was the method that they are known to have employed, was not so great as has been supposed. It has been recently discovered, from documents of that period, that certain Indians were actually building mounds in our southern States as late as the Revolutionary War. In the north, the practice of mound building had gone or was going out of fashion about a hundred and twenty-five years before, that is, in the days when the French first came to Wisconsin. It is thought that some of our Wisconsin mounds may be a thousand years old; while others are certainly not much over two hundred years of age, for skeletons have been found in some of them wearing silver ornaments which were made in Paris, and which bear dates as late as 1680.
