A young man was walking through a supermarket to pick up a few things when he noticed an old lady following him around. Thinking nothing of it, he ignored her and continued on. Finally he went to the checkout line, but she got in front of him. "Pardon me," she said, "I'm sorry if my staring at you has made you feel uncomfortable. It's just that you look just like my son, who just died recently." "I'm very sorry," replied the young man, "is there anything I can do for you?" "Yes," she said, "As I'm leaving, can you say 'Good bye, Mother'? It would make me feel so much better." "Sure," answered the young man.
As the old woman was leaving, he called out, "Goodbye, Mother!" As he stepped up to the checkout counter, he saw that his total was $127.50. "How can that be?" He asked, "I only purchased a few things!" "Your mother said that you would pay for her," said the clerk.

Taconite production

In 1933, the first cargo of taconite, a hard rock containing 25% - 30% iron, was shipped to the Ford Motor Company of River Rouge, Mich. The cargo had been produced 21 Jun 1922 by the Mesabi Iron Co. of Babbitt, Minn. The firm had begun operation in Nov 1919. Taconite is a low-grade ore containing only up to 30% magnetite and hematite as tiny particles scattered throughout a very tough variety of quartz called chert. The Mesabi Range, a giant area of low rolling hills in northeastern Minnesota is among the world's best known deposits of iron (discovered 1887). Mesabi is an Ojibwa name meaning "giant." After WW II, when other, higher grade iron ore had been depleted, an industrial method to exploit taconite ore was developed.
