And the Cenote of Sacrifice, that famous well, so vividly described by the early Christian priests, is now but a deserted shrine. Trailing vines, ferns, and palms almost cover the precipitous sides. The dark green waters are almost concealed by the slime of decaying vegetation. But the sight of the silent, sinister pool, surrounded by the unbroken forest, makes it easy, even now, to picture the scenes of sacrifice which it has witnessed.
