215. A few minutes ago every tree was excited, bowing to the roaring storm, waving, swirling, tossing their branches in glorious enthusiasm like worship… ~John Muir

…But though to the outer ear these trees are now silent,
their songs never cease.
Every hidden cell is throbbing with music and life,
every fiber thrilling like harp strings…
~John Muir, American naturalist and author

In this particular writing Muir eventually goes on to say that it’s “no wonder the hills and groves were God’s first temples.”  When one thinks about earth’s courts in such a way, he/she realizes that trees, whose roots are three times the size of the tree itself, monopolize large chunks of the planet’s hallowed ground, and so it’s not surprising that throughout the ages trees have been endowed with profound and sacred meanings.  For example, by observing the growth and death of trees, the flexible nature of their branches, the annual reoccurrence of their foliage, many have regarded trees as powerful symbols of growth, decay, and resurrection.  In addition to their aesthetic appeal, trees prevent soil erosion; they provide weather-sheltered ecosystems in and under their leaves; they play a vital role in the production of oxygen and the reduction of carbon dioxide; they moderate ground temperatures; and some even produce sumptuous orchard fruits.  Trees also speak to mortal men of the largeness and power of their Creator, and their lofty heights as well as the views afforded from them are envied by those who dare not climb their towering trunks.

The Lord God made all kinds of trees grow out of the ground–trees that were pleasing to the eye and good for food.  ~Genesis 2:9a  ✝

10. For in the true nature of things, if we rightly consider, every green tree is far more glorious than if it were made of gold and silver. ~Martin Luther

For man, autumn is a time of harvest, of gathering together.
For nature, it is a time of sowing,of scattering abroad.
~Edwin Way Teale

Like Teale I knew that autumn’s winds were scatterers and sowers, but until I did some research, I didn’t realize how much the autumnal shedding of leaves accomplishes.  For the sake of the sod, the fallen leaves cover the ground like a protective blanket.  It’s also easier for leafless trees to conserve much needed moisture in their branches and trunks, and since cold, dry winter winds strip moisture from trees through their leaves, losing their leaves is self-protective mechanism.  It would also be very costly energy wise for trees to keep their little leafy food factories up and running with less light and heat.   Because the transport of water from the ground into the trunk and leaves would be a damaging drain on a trees’ limited resources, the loss of leaves puts trees into a state of dormancy thereby reducing the amount of energy they need to live.  When leaves “come to rest upon the ground,” their work is far from over.  As they lie there, they become food for soil organisms which are vital to the overall health of ecosystems.  In addition the decomposing leaves restock the soil with nutrients and make up a part of the spongy humus that absorbs and holds rainfall.  And finally with the arrival of spring and warmer temps, bacteria, fungi, and insects come into play because the fallen leaves are chewed and rotted which in turn releases nutrients for plant growth.

“For the wisdom that fashioned the universe and can be read in earth’s dark depths and in heaven’s infinity of lights thanks be to you, O God.”  ~John Philip Newell
