room, but I would soon exhaust its life-giving qualities at night.
You know, mother," he went on in the assurance of his newly acquired
knowledge, "I guess the Lord knew what He was about when He enveloped
the earth with air which presses down nearly fifteen pounds to the

"'Of all the marvels of God's workmanship, none is more wondrous than
the air. Think of our all being bathed in a substance so delicate as to
be itself unperceived, yet so dense as to be the carriage to our senses
of messages from the world about us! It is never in our way; it does not
ask notice; we only know it is there by the good it does us. And this
exquisitely soft, pure, yielding, unseen being, like a beautiful and
beneficent fairy, brings us blessings from all around. It has the skill
to wash our blood clean from all foulness. Its weight keeps us from
tumbling to pieces. It is a reservoir where the waters lie stored, until
they fall and gladden the earth. It is a great-coat that softens to us
the heat of the day, and the cold of the night. It carries sounds to
our ears and smells to our nostrils. Its movements fill Nature with
ceaseless change; and without their aid in wafting ships over the sea,
commerce and civilization would have been scarce possible. It is of all
wonders the most wonderful.'"
