SKIMMING THE MILKY WAY.
THE COMET.
The comet is a kind of astronomical parody on the planet. Comets look some like planets, but they are thinner and do not hurt so hard when they hit anybody as a planet does. The comet was so called because it had hair on it, I believe, but late years the bald-headed comet is giving just as good satisfaction everywhere.
The characteristic features of a comet are: A nucleus, a nebulous light or coma, and usually a luminous train or tail worn high. Sometimes several tails are observed on one comet, but this occurs only in flush times.
When I was young I used to think I would like to be a comet in the sky, up above the world so high, with nothing to do but loaf around and play with the little new-laid planets and have a good time, but now I can see where I was wrong. Comets also have their troubles, their perihilions, their hyperbolas and their parabolas. A little over 300 years ago Tycho Brahe discovered that comets were extraneous to our atmosphere, and since then times have improved. I can see that trade is steadier and potatoes run less to tows than they did before.
Soon after that they discovered that comets all had more or less periodicity. Nobody knows how they got it. All the astronomers had been watching them day and night and didn't know when they were exposed, but there was no time to talk and argue over the question. There were two or three hundred comets all down with it at once. It was an exciting time.
Comets sometimes live to a great age. This shows that the night air is not so injurious to the health as many people would have us believe. The great comet of 1780 is supposed to have been the one that was noticed about the time of Caesar's death, 44 B. C, and still, when it appeared in Newton's time, seventeen hundred years after its first grand farewell tour, Ike said that it was very well preserved, indeed, and seemed to have retained all its faculties in good shape.
