Of course, I looked at once for an opening where the smoke arising from the hearth, etc., could have escaped. I am sorry to say, however, that I utterly failed in finding anything like a chimney,--not only in _B_, but in all the other buildings. Still, in the ruined condition of the place, this is no proof of their non-existence.[112] I will refer to subsequent pages to such articles of mechanical use and of wearing apparel which I was fortunate enough to meet. I shall also return hereafter to the almost omnipresent pieces of painted pottery, of two distinct kinds, and to the very numerous chips of obsidian, jet-black on the face, but transparent as smoky glass; of black lava; and to the flint, jasper, and moss-agates, broken mechanically by man, and scattered over the premises. These premises have been thoroughly ransacked by visitors, and every striking object has already been carried off. I had heard mentioned, among such samples, flint, agate, and obsidian arrow-heads, stone hatchets and hammers, and copper (not brass or iron) rings used for ornamental purposes,[113] but my luck it was not to find any. Therefore the harvest is perhaps slim in that respect. It is beyond all doubt that judicious digging among the lower stories of the structures will reveal treasures,--not money, as the tale current among the inhabitants has it, but things of archæological and ethnological value. For such an undertaking I was, as the Institute well knows, not prepared. I attempted to dig, indeed, though quite alone, but soon came to the conclusion that the time consumed in excavating one metre of decayed and crumbling stones and earth would be more satisfactorily employed in other directions; paving the way for the exhaustive labors of better situated archæologists. I have been very lengthy in my _exposé_ of facts and data regarding this particular house _B_, for the simple reason that, as far as the principles of architecture, based upon a knowledge and want of "how to live," are concerned, it is typical of the rest. Many details become therefore unnecessary in subsequent descriptions.
