Turning now to the inside of the building itself, I am compelled to acknowledge here an important omission in my survey of _B_. It relates to the vertical connection of the walls. They are all, with few exceptions, as far as their dilapidated condition admits of observation, continuous from bottom to top; that is, the sides were everywhere carried up above the ceiling (or floor), and then, after the beams had been embedded in the stones, another wall was piled up on it as straight as possible. In this manner it became possible to add each cell separately. There are several doors visible in _A_, as marked on the ground-plan. Those in the eastern and western wings open from east to west, those in the northern wing from north to south; therefore transversely to the length of each structure. But I have also seen longitudinal walls without passages. The tops of the doors are all gone; the rest is everywhere similar to the sample found in _B_, and already figured. In some cases even the sills are gone. Windows I could not find, nor trap-doors or ladders; there was no trace of steps, and, unfortunately, no clew to any chimney or vent. Of furniture I secured pieces of new hearth-stones; of other articles, broken "metates," part of a fine maul of stone, flint chips, celts, stone skin-scrapers, and, of course, painted pottery and obsidian. But not one specimen is entire; every striking implement, etc., has been carried off by amateurs, of whose presence besides broken beer bottles, with the inscription "Anheuser-Busch Brewing Co., St. Louis, Mo.," give occasional notice.
