that have
been brought to light comprise a number of chambers, big and little,
placed at different heights. We shall have no clear idea of the relation
of these different chambers to one another, or of the mode of access to
them through the labyrinthine passages and the numerous stairways, until
the whole edifice has been unearthed."

This was not the only building he discovered. On digging into a mound
supposed to be the support of a temple, he discovered it was the ruined
foundation of a still grander house. He says, "It is much larger than
the other one, stands on a pyramid, and has two wings inclosing a
courtyard. The walls are thicker than those of the first habitation, and
more strongly built. The apartments, too, are larger, though arranged in
a similar fashion." Elsewhere he tells us that this building contained
at least forty-three apartments, large and small. We presume very few
will now question but what the buildings he here describes are ruined
communal buildings, much like the structures in Arizona.

But perhaps the most interesting result of his labors was the proof that
these ruins were certainly inhabited after the conquest--for how long
a time we can not tell. This is shown by fragments of bones and other
articles found in the refuse heaps. The bones were of such animals
as the horse, swine, sheep, oxen, etc.--animals introduced into this
country by the Spaniards. The fragments of pottery include specimens
plainly not of Indian manufacture, such as fragments of porcelain, and
that variety of glazed ware known as delf, and lastly, the neck of a
glass bottle. It may be said that these fragments might have been left
by a band of Spaniards who occupied the ruins in the early days of the
conquest, perhaps long after the Indian owners had left. This is of
course possible, but it is just as reasonable to suppose the fragments
were left by descendants of the original builders.

Northward from Tulla is a small province, marked on the map Querataro.
From the accounts at our disposal, which are very brief, we gather that
this whole section is a tableland split up by ravines of great depths
and precipitous sides; consequently one abounding in easily defended
positions. It was found that all the projecting points, naturally
strong, were rendered still stronger by the presence of ditches, walls,
and embankments. Three groups of ruins are mentioned especially, and
their location is marked on the map. At Pueblito th
