Don't Stare At A Red Tree It May Be A Blushing Maple
"Even trees have personalities," said Dr. A. J. Mix, head of the botany department, today in an interview by a University Daily Kansar reporter.
reporter.
"This is manifested mainly in the way you change color in the fall," he said. "For instance you can see two trees in the same locality, and of the same type where one of them is a mass of bright colors and the other looks all washed out. This is only an example of individual personality."
"Anthocyans are soluble coloring materials which are influenced by the chemical make-up of the cell sap. It is present in nearly all plants. If the sap is acid, a red color results, if it is alkaline, blue is formed, and if it is neutral, the plant is purple. Other factors affect the red coloring of the leaves.
"We do not know for sure where the red coloring comes from," he said, "But we know it is caused by anticyans contained in leaf structure."
When asked what happens each fall when all the foliage changes color, Dr. Mix said that it is not known exactly what does occur.
"There is little mystery to the formation of yellow and orange which is so common during this season." Dr. Mix continued.
"Leaf cells contain chlorophyll, which makes food for the plant and is green colored, and xanthophyll, a yellow substance which assists in the operation. In cooler weather, the chlorophyll recedes, leaving the yellow material visible. Orange colors depend on the amount of carotene, a vitamin found mainly in carrots, which is present in the leaves of some plants." Dr. Mix explained.
"We have found that the amount of sugars and tannins present in the leaves will determine reddish tints. Mapies, which have large amounts of sugar, are more likely to turn red than are the elms or more neutral trees.
When asked why the color of a tree's foliage varies from year to year, Dr. Mix answered.
"We have found that a sudden drop in temperature is more likely to cause violent changes of the colors. It does not necessarily have to freeze, but if it becomes chilly suddenly the trees change much more in color. The location of a tree will also effect the coloring of it.

"If you will notice, trees in the sun are usually brighter colored than are those which are in the shade. We don't know why that is but probably it is because the sun aids the chemical reactions which take place."
The next time you look at a tree all decked out in fall colors, you can be sure that each leaf on it went through a rather complicated procedure to get that way.

Here, in question and answer form, are some facts on the U. S. Air Force Aviation Cadet program. They cover details you may have been
1. Who is eligible for appointment to the Cadets?
You, if you're physically fit, single, between 20 and $ 2 6 \frac{1}{2} $ years old, and have completed at least one-half the requirements for a college degree from an accredited institution - or pass an equivalent examination.
You receive approximately 52 weeks' training worth $35,000 - in primary, basic and advanced flying, along with other related courses designed to give you the finest background in your specialty.
2. How long does the training last - and what does it cover?
After successful completion of the course, you will be commissioned a Second Lieutenant, Officers Reserve Corps, and assigned to pilot duty with the U. S. Air Force at a starting monthly salary of $336 (including flight pay). You will serve on active duty for three years unless sooner relieved, and be eligible for $500 a year bonus for each year of active duty as a Reserve Officer. If you're interested in a Regular Air Force commission, you'll be given a chance to qualify.
3. What's the story on duty after graduation?
4. What are the civilian career opportunities?
That's one you can answer for yourself by taking into consideration these facts: Contrary to what some people think, aviation is not overcrowded - for pilots or anyone else. No field is expanding more rapidly or offering more profitable openings to qualified men. After Aviation Cadet training, you can compete on an equal basis with any flier in the world.
These are only a few of the advantages. Why not stop in today at your nearest U.S. Army and U.S.Air Force Recruiting Station and get all the details?
