Getting to Heaven from the Post Office

A preacher, newly called to a small country town, needed to mail a letter. Passing a young boy on the street, the pastor asked where he could find the post office.
After getting his answer, the minister thanked the boy and said, “If you’ll come to the community church this evening, you can hear me tell everyone how to get to heaven.”
“I don’t know, sir,” the boy replied. “You don’t even know how to get to the post office!”

Adding machine

In 1887, a patent for the adding machine was granted to Dorr Eugene Felt of Chicago, Illinois. His Comptometer was the first practical key-driven calculator with sufficient speed, reliablility and economic benefit. He called his original prototype the "Macaroni box", a rough model that Felt created over the year-end holidays in 1884-85. The casing was a grocery macaroni box, assembled with a jackknife using meat skewers as keys, staples as key guides and elastic bands for springs. Door improved his design, producing his earliest commercial wooden-box Comptometer from 1887 thru 1903, leading to the first steel case Model A (1904 that would be standard for the remainder for all "shoebox" models. Electric motor drive was introduced in the 1920's.
