　　A

　　To Miss Doughty

　　16 September 1962, Sunday

　　My dear,

　　Well, here we are-but not here. You are in Princeton,and me in Quogue,and another brand new year is about to start for you. For me, too.

　　It is the beginning of a big year for you, in many respects your biggest so far. By the time, June comes around, you will be 18, and graduating from school. In the past week or so I have called you"Kid", but subconsciously I have been doing that because your kid days are over, or just about. I suspect that you are going through the experience of first love, and no matter what else happens, after that experience you are never a kid again.

　　Most of the nice things we associate with being a kid are okay while you are still a kid. But you gain more than you lose. You gain in understanding standing, in appreciation of people, in un-derstanding and appreciation of people. You begin to see the wisdom in that quotation I have so often repeated to you: to thine own self be true. Every year at this time I have repeated that quotation to you, and the time is not really too far distant when you will be passing it on to your own children. It is probably the best single piece of advice I can give you, or you can give them.

　　You have done well, and I am pleased with you, not only for what you have done, but for what you are. So good luck in your Senior Year, and always know that the old man loves you very much.

　　There are colleges that have four-year graduation rates in the single digits. A 30% rate isn' t at all unusual, especially among regional public universities.

　　If you are applying to colleges, probably your goal is to get a college degree. Some schools are much more successful at graduating students than others. If the majority of the students at a college don' t graduate in four years, then they are spending more money for a goal that will evade them.

　　When you are calculating the cost of a college degree, you should take graduate rates into ac-count. If most students take five or six years to graduate, you shouldn' t plan on increased earning potential because of your degree.

　　Make sure you put graduation rates into context. There are often good reasons why some schools have larger graduation rates than others.

　　Professional progress in fields such as engineering, nursing and education are more likely to take five years than many other fields in the humanities, science and social science.

　　Many state universities have a large percentage of commuting students, working students and students with families. The demands on these students often making graduating in four years difficult.

　　These schools provide an important role by making college accessible to all, at the same time,they will often admit students who are entirely unprepared for the demands of college academics.

　　Hair loss can be destructive for the millions of men and women who experience it. Now scientists are reporting that a substance from honeybee hives might contain clues, for developing a potential new therapy.

　　They found that the material, called propolis, encouraged hair growth in mice. The study appears in ACS Journal of Agricultural and Food Chemistry.

　　Ken Kobayashi and colleagues note that propolis is a resin—— like material that honeybees use to seal small gaps in their hives. Not only does it work as a physical barrier, but it also contains active compounds that fight fungal and bacterial invasions. People from ancient times had noticed propolis' special properties and used it to treat tumors, inflammation and wounds. More recently,research has shown that the substance protnotes the growth of certain cells involved in hair growth though no one had yet tested whether that in turn would result in new locks. Kobayashi' s team wanted to find out.

　　When the researchers tested propolis on mice that had been shaved or waxed, the mice that received the treatment regrew their fur faster than those that didn't. The scientists also noticed that after the topical application, the number of special cells involved in the process of growing hair increased. Although they tried the material on mice that could grow fur rather than balding mice, the researchers note that hair loss conditions often result from abnormal inflammation. Propolis contains anti-inflammatory compounds, so they expect it could help treat balding conditions. They add that further testing is needed to see if the beehive material affects human hair follicles.
