make any intelligible reply to the simplest question.

We pushed on rapidly, and in a few moments more I stood upon the summit
of the pyramidal structure, upon which, as a base, the ruins known as
_El Palacio_ are situated.

These ruins have been so frequently described, that I deem it
unnecessary to enter into any detailed account of them; especially as by
doing so but little progress would be made with the more important
portions of this narrative. If, therefore, the reader be curious to get
a more particular insight into the form, size, and appearance of these
curious remains, let him consult the splendidly illuminated pages of Del
Rio, Waldeck, and Dupaix. Nor should Stephens and Catherwood be
neglected; for though their explorations are less scientific and
thorough than either of the others, yet being more modern, they will
prove not less interesting.

Several months had now elapsed since I swung my hammock in one of the
corridors of the old palace. The rainy season had vanished, and the hot
weather once more set in for the summer. Still I worked on. I took
accurate and correct drawings of every engraved entablature I could
discover. With the assistance of my taciturn guide, nothing seemed to
escape me. Certain am I that I was enabled to copy _basso-rilievos_
never seen by any of the great travelers whose works I had read; for
Pio seemed to know by intuition exactly where they were to be found. My
collection was far more complete than Mr. Catherwood's, and more
faithful to the original than Lord Kingsborough's. Pio leaned over my
shoulder whilst I was engaged in drawing, and if I committed the
slightest error his quick glance detected it at once, and a short, rough
whistle recalled my pencil back to its duty.

Finally, I completed the last drawing I intended to make, and commenced
preparations to leave my quarters, and select others affording greater
facilities for the study of the various problems connected with these
mysterious hieroglyphics. I felt fully sensible of the immense toil
before me, but having determined long since to devote my whole life to
the task of interpreting these silent historians of buried realms, hope
gave me strength to venture upon the work, and the first step toward it
had just been successfully accomplished.

But what were paintings, and drawings, and sketches, without some key to
the system of hieroglyphs, o
