The Gift

On the first day of school, the children brought gifts for their teacher. The florist's son brought the teacher a bouquet of flowers. The candy-store owner's daughter gave the teacher a pretty box of candy. Then the liquor-store owner's son brought up a big, heavy box. The teacher lifted it up and noticed that it was leaking a little bit. She touched a drop of the liquid with her finger and tasted it.
"Is it wine?" she guessed.
"No," the boy replied. She tasted another drop and asked, " Champagne ?
"No," said the little boy... "It's a puppy!"

Born 7 Aug 1726; died 6 Nov 1790 at age 64.American founder and first president of the American Academy of Arts and Sciences (1780). He was a scientist prominent in physics and astronomy, and wrote several papers including one on electricity with Benjamin Franklin, a close friend. In one of his letters to Franklin, Bowdoin suggested the theory, since generally accepted, that the phosphorescence of the sea, under certain conditions, is due to the presence of minute animals. Bowdoin was also a political leader in Massachusetts during the American revolution (1775-83), and governor of Massachusetts (1785-87). His remarkable library of 1,200 volumes, ranged from science and math to philosophy, religion, poetry, and fiction. He left it in his will to the Academy.
