Live Oak

This is an oak tree. It lives about an hour from my house here in southeast Texas.


Please look at the tree. You may click the picture to see a larger image.

Notice its massive trunk. This tree is estimated to be over 1,000 years old. The trunk is estimated to be 35' in circumference. That means if it were (God forbid) pushed over, the trunk by itself and at its narrowest point would be more than two stories tall. The trunk does not grow very tall before it starts to branch out, patiently supporting the branches, which in turn provide sustenance for the trunk.

Now, please notice the branches. Some of these branches are bigger than most trees. The lower branches move out almost parallel to the ground, their massive weight belying the graceful arc they trace in the air. These branches look like they might move under strain. Believe me, except for under hurricane force winds - which this tree has experience many of, the branches do not move. Another tree closer to where I live had a pulley attached to it which was used to pull engines from automobiles. That tree, which I've swung on a rope swing on, is only about 1/2 the size of this. Oak wood has been renowned for a long time for its strength and integrity. It is also quite beautiful when worked. The branches of this tree would provide as high a quality of wood as would the trunk. Also, due to the weight of the branches, the forks of these branches would provide some amazing figure - called fiddle back and/or flame. This is formed in the wood as the branches weigh down on the trunk below, causing distortion in the wood itself.

Please notice that the branch to the right requires additional support. This is most likely for aesthetic reasons, and to keep people from damaging the low-hanging branch, and not necessarily for the health of the tree. I've seen live oak trees with branches growing wild and hanging low to the ground. The posts holding that branch up are probably 6' or 8' high. Just to give you an idea of the scale.

The purpose of the branches, of course, is to provide sustenance for the tree. The tree, in turn, exists to create fruit - acorns - to propagate the species. This tree has produced acorns for a thousand years. These acorns are eaten by local animals, which in turn are eaten by other animals. All of these animals produce fertilizer for the local plants, which feeds the plants and begins the cycle anew. The branches also pull carbon dioxide and nitrogen out of the air, trapping it in the sugars used by the tree itself.

One of the unique aspects of the live oak is that they do not lose their leaves - at least, there's never a time when they are devoid of leaves. Other oaks will drop their leaves in the winter. But live oaks keep their leaves all winter long. They are more accurately called evergreen oaks.

The part you don't see, and this is the part that is truly impressive to me, is the root system. The roots of the tree are at least as extensive as the portion we see above ground. Pushing deep for water and nutrients, the roots also anchor the tree, enabling it to weather the storms that come in this coastal area.

This oak is a gnarled, ancient tree that has lived for a thousand years. Yet, one day, this tree, too, will die. It may be a fire, it may be global climate change induced sea level rise. More likely it will be a hurricane that will eventually topple this mighty tree. It would take sustained winds of a category 5+ storm that would be able to knock this thing over.

Interesting to think that air - something we can't even see and usually feel as gentle, warm breezes here off the Gulf - could cause the death of something so mighty.

Grandpa is like the oak tree.

I'm more of a maple, myself... ;-)

You can also make some mighty fine things out of maple.

Maple? Your leaves turn in fall and your sap runs in the spring.

I guess when you boil it down you are mighty sweet.

Ephesus

Paul got around. Ephesus is right on the Aegean Sea, on the coast of present-day Turkey. Yesterday he was in Galatia, which was much more towards the middle of Turkey. And when he actually wrote these letters, he was in Rome... So the man could travel. He probably walked. Today's item of interest comes from chapter one in Ephesians. Verses 18 and 19 are particularly interesting: 18 The eyes of your understanding being enlightened; that ye may know what is the hope of his calling and what the riches of the glory of his inheritance in the saints, 19 And what is the exceeding greatness of his power to us-ward who believe, according to the working of his mighty power This is not the first time Paul talks about an inheritance. In Galatians he talks about the inheritance that comes of being part of the Abrahamic Covenant. He notes that we are joint-heirs through and with Christ. In Ephesians, he uses the word "adoption" - that we are adopted as the Children of Jesus Chris...

Engaged

Three Dog Night got it wrong.  One is not the loneliest number. They were more accurate when they said Two can be as bad as one.  I really wonder how people can survive Without being fully engaged. How they live through each day Without the intimacy I so very much crave... Maybe I am unusual in my desire  To have this intimacy, To want to feel that soul So close to my own Sharing light and warmth, Sharing love and passion, Sharing life. Alas! Alas! Alas! For when I do seek to share It is often only to be rebuffed Denied Or used up, Sucked dry, And left an empty husk.  I want SO MUCH to share And all I have is the cold, digital world Of typing out a blog.

The Other Art

I'm not sure we appreciate photography as much as we do other art forms. Part of this comes from the reality that surrounds and permeates a photograph - it's very, very real, and the photographer strives for clarity and crispness in the representations. Perhaps this is why black and white images continue to be relevant - they strip away extraneous information (color) and leave us with something that is at once familiar and also non-existent - for nothing exists in black and white. Nothing. I also think that pictures are becoming too common-place... Everyone has a camera in their pocket, and while that's a very democratic thing (everyone can express themselves in a picture easily and readily, and can find an audience for these images, which are casually taken and casually viewed, and perhaps just as casually forgotten) I think that we embrace that casual attitude, and it spills over to all aspects of the media, making it impotent. So I read this article this morning: h...
