But let us not undervalue ourselves--which would, in fact, be to undervalue our Creator--for such shortcomings. Though into our iron horse's skull or cab we have to put one or two living men to supply its deficiency of understanding, it is nevertheless a recognizable animal, of a very grand and somewhat novel type. Its respiratory, digestive, and muscular systems are respectable; and in the nature and articulation of its organs of motion it is clearly original. The wheel, typical of eternity, is nowhere to be found among living organisms, unless we take the brilliant vision of Ezekiel in a literal sense. The idea of attributing life or spirit to wheels, organs by their nature detached or discontinuous from the living creatures of which they were parts, was worthy of a prophet or poet; but to no such prophetic vision were the first wheelwrights indebted for their conception of so great an improvement upon animal locomotion. For if they had not made chariots before Noah's flood, they certainly had done it before Pharaoh's smaller affair in the Red Sea. On that occasion, the chariot-wheels of the Egyptians were taken off; but this does not seem to have produced effects so decisive as would result from a similar disorganization in Broadway or Washington Street; for the charioteers still "drave them heavily." Hence we may infer that the wheels were of rude workmanship, making the chariots little less liable to the infirmity of friction than those Western vehicles called mud-boats, used to navigate semi-fluid regions which pass on the map for _terra firma_.
