A nursery school teacher was delivering a station wagon full of kids home one day when a fire truck zoomed past. Sitting in the front seat of the fire truck was a Dalmatian dog. The children began discussing the dog's duties.
"They use him to keep crowds back," said one youngster.
"No," said another. "He's just for good luck."
A third child brought the argument to a close with this comment: "They use the dogs," she said firmly, "to find the fire hydrants."
Waldemar LindgrenBorn 14 Feb 1860; died 3 Nov 1939 at age 79.Swedish-born American economic geologist who was a leader in the science of ore deposition and the use of the petrographic microscope. He helped establish that veins of metal and similar deposits are created by hot solutions derived from molten rock below, not by water seepage from above. His interest in geology began as a youth from reading a book on mineralogy and a visit at the age of 10 to the west coast of Sweden where rocks are beautifully exposed. By the time he was 17 he had seen the mines of central Sweden and the famous old silver workings of Kongsberg in Norway. As a young mining geologist, he emigrated to America in Jun 1883, drawn by the rapidly growing mining industry of the Western United States. |
