[Illustration] If you will knock the top off this trunk you will discover the clothing of a mean man. In case you can not knock the lid entirely off, burst it open a little so that the great, restless, seething traveling public can see how many hotel napkins and towels and cakes of soap he has stolen. [Illustration] This is the trunk of a young girl, and contains the poor but honest garb she wore when she ran away from home. Also the gay clothes she bought after a wicked ambition had poisoned her simple heart. They are the gaudy garments and flashy trappings for which she exchanged her honest laugh and her bright and beautiful youth. Handle gently the poor little trunk, as you would touch her sad little history, for her father is in the second-class coach, weeping softly into his coarse red handkerchief, and she, herself, is going home on the same train in her cheap little coffin in the baggage car to meet her sorrowing mother, who will go up into the garret many rainy afternoons in the days to come, to cry over this poor little trunk and no one will know about it. It will be a secret known only to her sorrowing heart and to God. A MEDIEVAL DISCOVERER XXI Galilei, commonly called Galileo, was born at Pisa on the 14th day of February, 1564. He was the man who discovered some of the fundamental principles governing the movements, habits, and personal peculiarities of the earth. He discovered things with marvelous fluency. Born as he was, at a time when the rotary motion of the earth was still in its infancy and astronomy was taught only in a crude way, Galileo started in to make a few discoveries and advance some theories of which he was very fond. He was the son of a musician and learned to play several instruments himself, but not in such a way as to arouse the jealousy of the great musicians of his day. They came and heard him play a few selections, and then they went home contented with their own music. Galileo played for several years in a band at Pisa, and people who heard him said that his manner of gazing out over the Pisan hills with a far-away look in his eye after playing a selection, while he gently up-ended his alto horn and worked the mud-valve as he poured out about a pint of moist melody that had accumulated in the flues of the instrument, was simply grand. At the age of twenty Galileo began to discover. His first discoveries were, of course, clumsy and poorly made, but very soon he commenced to turn out neat and durable discoveries that would stand for years. It was at this time that he noticed the swinging of a lamp in a church, and, observing that the oscillations were of equal duration, he inferred that this principle might be utilized in the exact measurement of time. From this little accident, years after, came the clock, one of the most useful of man's dumb friends. And yet there are people who will read this little incident and still hesitate about going to church.
