The average pit may be said to be filled with ashes in more or less well-defined layers. Near the top there may be a mixture of gravel, but underneath are found only fine gray ashes to the depth of one or two feet, in which often occur thin strata of charcoal or sand, while at the bottom burnt stones have often been found. Throughout the whole mass of ashes and sand, from top to bottom, are bones of fishes, reptiles, birds, and mammals. The larger bones, such as those of the elk, deer, and bear, are broken; and all, apparently, are those of animals used for food. With the bones are always many shells of fresh-water mussels (_Unionidae_), the more massive of which have a large circular piece cut out near the centre. Fragments of pottery (rarely a whole vessel) also abound in each pit, quantities of implements made of bones and antlers, some forms of which are unlike anything known elsewhere, implements of chipped and polished stone, pipes carved in various shapes from stone, and objects of copper. In some pits several bushels of charred corn, which had been covered with bark matting, lay underneath the ashes; and in three instances human skeletons, or parts of skeletons, have been found in the pits,--a fact which seems to have no special significance. On the hill-side near this great cemetery is to be seen what doubtless is the site of the permanent village of the people who made the ash-pits. This site is indicated by several earth-circles, the explorations of which, prosecuted by means of trenches, revealed in the centre, upon the hard clay, beneath about two feet of accumulated leaf-mould, fireplaces made of large stones, enclosing beds of ashes mingled with potsherds, flint-flakes, burnt bones, and perforated shells like those in the pits. The few things disclosed within the circles, and the abundance of household-utensils and refuse found in the ashes in the pits, suggest the possibility that on special occasions all the articles in the house, with ornaments, weapons, and other personal property, were partly destroyed by fire, gathered up with the ashes, and deposited in a pit dug for the purpose, while the great number of broken bones of various animals indicates that at such times feasts were held. A custom like this, which is quite consistent with the Indian character as manifested within the historic period, would account for the character of the contents of the pits, while their great number would indicate a long-continued occupation of the village.
