By assisting each other the three castaways were soon where such a marvelous sight was presented that exclamations of surprise and admiration burst from their lips; but, fortunately, the chattering of the monkeys would have prevented the outcries from being heard had a party of Chan Santa Cruz Indians been at the foot of the tree.

Far to the eastward was a long range of low, rocky mountains, and at the north and south spurs or cliffs, all enclosing a beautiful valley in the center of which was a city of dazzlingly white buildings.

To look at this collection of houses and temples very long at a time was almost impossible because of the peculiar glare which the boys had mistaken for the sun's rays.

It was caused by the reflection of the god of day on an edifice in the center of the city, the dome-like roof of which was covered with a burnished metal substance having the appearance of silver.

The adjoining buildings, composed of white stone having a softness as of alabaster, threw this peculiar light in every direction, causing the city to stand out amid the green foliage like a huge incandescent mass.

Each house stood in a square by itself, and, judging from the area of the city one might have estimated the population at about fifteen thousand. The streets were laid out with the utmost precision, and composed of what appeared to be fine white sand, while at every intersection were monuments of grotesque figures or animals.

At regular intervals were enormous white columns capped with the glistening metal, the same as displayed on the dome of the principal building and on many of the houses.

After taking in this wonderful picture as a whole the boys gazed at the most prominent objects in turn, the central edifice occupying the greater share of attention.

That this was a place of worship seemed reasonable to suppose because of the crowds of people entering or departing from the opening formed by lofty pillars of shimmering metal, and also because of the tiny threads of smoke which arose from several apertures in the roof as if from altar fires. To confirm the beholders in this belief the faint sound of sweet music arose in the air, and instantly the throngs in the streets prostrated themselves in adoration of some one of the statues.

The citizens were dressed in flowing garments of white, and all seemed intent on worship which was prolonged until after the spectators left the tree.
