THE BRIDGE OF CAÑON DIABLO.

The art of bridge-building in some form or other is one of the earliest necessities of civilization. Even the apes in equatorial regions will link themselves together, and swing their living line across a stream to trees on the opposite bank, thus forming a connected path of bodies along which other monkeys pass in safety. Bridges of ropes or reeds are, also, made by the most primitive of men; while viaducts of stone rose gradually in perfection, from the rude blocks heaped up by savages to the magnificent structures fashioned by the Romans. But with the introduction of iron and steel into their composition, bridges are now constructed quickly, with consummate skill, and in a multitude of different forms assist in making possible the safe and rapid transit of our great Republic.

SKULLS OF CLIFF DWELLERS.

In addition to all the wonderful natural features of Arizona and New Mexico, the insight into ancient and modern Indian life which they afford is of extraordinary interest, particularly as aboriginal civilization, evidently, reached a higher level here than was attained by any of the tribes which roamed throughout the regions now known as the Middle and Eastern States. The natives of the arid regions of the great Southwest, though subdivided into numerous tribes, are usually known under the general title of Pueblos. The name itself, bestowed upon them by the Spaniards, is significant; since pueblo is the Spanish word for village, and this would seem to prove that the race thus designated three hundred and fifty years ago was not nomadic, but had been settled here for many years.
